肌肉分为哪几种?

人体的肌肉(Muscle)可分为三大类,即平滑肌、心脏肌和骨骼肌。各有不同的特性及功能。

平滑肌

存在於心脏以外的其他内脏器官,如胃肠道、泌尿道、呼吸道和生殖器统管道等,这类肌肉不但在显微镜的观察下有其特别的形态,而且它绝大多数的情况下不受个人的主观意识控制,而是由内脏本身的自主神经系统和血液内的荷尔蒙调节。

心脏肌

只限於心脏腔室内,它同样也是不受主观意识支配,它有规律的搏动形成了心跳;心跳在人体生存的每一分每一秒钟都在进行著。这个节律的起源来自右心房内的一组特殊且专门的心肌细胞,医学上称为起搏点(Pacemaker)。

起搏点细胞会随著细胞内外的钠钾和其他电解质的浓度交替变化,形成脉冲式的电流。这些电流再通过心肌内的特殊传导组织,扩散到心肌的其他部位。由於心脏内电流的传送速度异常快速,所以左右心室两个腔室的心肌,几乎是同一时间接受到神经冲动信号,因而产生一致性的收缩,将心室内的血液强力而有效地泵出。左右心房两个腔室则在下一个神经冲动到来之时一齐搏动。搏动之后跟随著极短暂的时间让心肌放松,然后才再进行新一轮的搏动周期,如此循环不止。

骨骼肌

这种肌肉的最大特点是可由个人意识控制收缩的时间、幅度和强度,而且这类肌肉的尺寸大小可随著训练、使用的程度而出现显著的变化;其他影响肌肉粗幼的因素包括遗传因素、营养、荷尔蒙等。

骨骼肌的功能是通过收缩使它所附著的骨骼运动,来完成人体各类活动的所需。按照肌肉纤维收缩的快慢又可将骨骼肌分为快肌和慢肌两种。

慢肌即是所谓的红肌,这由於它的微细血管分布丰富,肌肉细胞内的糖元和线粒体都较少,所以它主要是依靠有氧呼吸代谢产生的能量来供给肌肉的收缩之用。这类肌肉的收缩速度较缓慢,爆发力差,但能较持久,不易产生疲劳,是日常生活活动的主要肌群。

快肌又有人称之为白肌,肌肉细胞内糖元和线粒体较多,而微细血管则相对较缺乏,它主要是通过无氧呼吸代谢产生的能量来进行收缩活动,故能在很短的时间内快速地运动,产生巨大的爆发力,但较易疲劳,不耐持久。这类肌肉常用於短跑、跳远、举重、推铅球等。在日常生活运动中则专门用於精细和灵敏的运动中,如手部肌肉和眼球肌肉则属这一类。

根据结构和功能的不同,人体肌肉可分为骨骼肌(又叫横纹肌)、平滑肌、心肌三种。按着是否可以随人的意志而收缩,可分成随意肌和不随意肌。骨骼肌是随意肌,心肌、平滑肌是不随意肌。骨骼肌,就是使骨头活动的随意肌;运动系统所讲的肌肉属于骨骼肌,它能在意识控制下做强力的收缩,人的四肢、躯干上可以自由活动的肌肉都属于这一类。在神经的支配下,肌肉收缩产生运动。一个人有600多块骨骼肌。  平滑肌,就是为血管、胃、消化器官以及其他内脏充当衬里的不随意肌;人的内脏大部分是平滑肌,平滑肌不受意识支配,不能随意活动,但受植物性神经支配,因此保持经常收缩、放松,但收缩力不大,缓慢持久,不易疲劳。  心肌,就是心脏所特有的肌肉组织,能自动地有节律地收缩。心肌也具有纹理,但纹理比骨骼肌疏。心肌也是不随意肌。心脏以一定的速率跳动,不随人的意志而改变。

人的肌肉按照耐力分为白肌和红肌2种。白肌能充分把血糖或者脂肪分解为ATP或者能量

以及热量,同时产生少量尿酸。但是过程很缓慢。红肌能瞬间利用ATP转化为能量,也能短时间内利用血糖和脂肪转化为少量能量以及大量的尿酸(通过尿液过者皮肤排除体外,尿酸是人体中最多的毒素。这也是人们为什么喜欢和茶来消除疲劳的原因)。

黑白混血人体内的红肌是所有人种中含量最高的,大约有42%,其次是白人,再次黑人,最少的是黄种人,但是黄种人含的白肌是最多的,所以耐力力最好。

肌肉有收缩作用,因而能使人体在空间的位置发生改变,并维持呼吸、心跳、胃肠蠕动等脏器的活动。肌肉分骨骼肌、平滑肌和心肌三种。骨骼肌可随意志自由活动,所以又叫随意肌。平滑肌和心肌不能随意志自由活动,所以又叫不随意肌。

一般所说的肌肉是指骨骼肌。骨骼肌约占人体的40%。该肌肉是细肌纤维的集合体,一般呈纺锤形。在显微镜下观察,这种肌纤维可见横纹,所以又叫横纹肌。

肌肉周围为有弹性的薄肌膜包裹,纺锤形的中央部为红色,很软,但与骨骼相连的部分为白色并有光泽,有极强的韧性。这个红色部分叫肌腹,白色部分叫肌腱。肌腱是连接骨和肌肉的纤维性结缔组织,因肌肉不同而有长有短。人们所熟知的跟腱,就是与活动腿的腓肠肌相连的很粗的肌腱。

肌肉能收缩,是由于来自神经的刺激传给肌纤维,并在那里发生化学变化所致。

心脏起搏器简介

目录 1 拼音 2 英文参考 3 心脏起搏器的发明 4 心脏起搏器的类型及发展 1 拼音 xīn zāng qǐ bó qì 2 英文参考 cardiac pacemaker cardiac pacer heart pacemaker heartpacer pacemaker of heart 心脏的节律起搏是由右心房的窦房结自动地有节奏地发出电脉冲,通过神经传导系统向心脏各部位发出指令使心肌收缩。如若神经传导系统发生障碍或者窦房结不能有规律地发出电脉冲,心脏起搏器可以对患病的心脏给予直接电 *** ,人为地使心搏数正常起来。 3 心脏起搏器的发明 早在 1802年,意大利人奥尔蒂尼曾对用刑后死去两小时的死刑犯给予电 *** 心脏,以图恢复其心跳,但未成功。同时代的瓦萨里用电 *** 法曾成功地使刚刚死亡的患者心已脏又恢复跳动。1947年斯威特采用电 *** 法使两例在手术中心脏停止跳动的患者心脏复苏。这种通过电 *** 的方法实现人工心脏起搏的范例,为研制心脏起搏器打下了技术和理论基础。 1952年美国波士顿哈佛医学院的佐尔医生,在心脏停跳患者的心脏部位和左肋下皮肤处置阴阳两电极,给予每分钟90次的电 *** 而使心脏复跳。他随即研制出以电池为能源的小型起搏器。佐尔被认为是心脏起搏器的发明者,被称为“心脏起搏器之父”。现在全世界有数十万人装了心脏起搏器,挽救了许多患者的生命。 4 心脏起搏器的类型及发展 起搏器主要有体外式和体内埋植式。体外式使用方法简单,在紧急情况下使用,对患者进行抢救非常方便。还可根据患者的状况变换心搏数。但是如果长期使用,在放置电极的部位容易发生感染。 采用体内理植式,将起搏器植入病人腹部或腋窝皮下,对长期使用者非常方便,但起搏器心搏数固定也会带来各种问题。近年来已经研制出可以变动心搏数的诱导型起搏器。电极和接收器植于体内,用发送器在体外控制,这样便可以根据情况变更心搏数。

临终处理常识 – 取出亡者起搏器问题.

更新1: 智南师兄 多谢解答. 不用ue186心 那只是件往事. 想想如果佛子能预早有备 那便不用太忙乱或遗撼. 这种事总令人忙乱. 爱有ue186念 我等凡夫有执. 能祝福一点便安乐一点. 当日我没心理准备 临时要像流难医护的人去拖延解剖 心情难受之时 我语言亦不懂柔软解释. 而解释对方亦不一定能明白. 相方亦不好受. 更新2: 可能在危怠预知人不能回转时 家人能预早跟医护沟通临终安排 那事情对谁都和谐顺利些. 有些甚么在医院运作中可行 有些甚么不可能……在可能的做到妥善. 据我所知 学院中有人的宗教信仰须要包头 学校的校服规则会包容. 囚犯宗教不能吃猪肉 食物亦有特别安排. 所以我相信 宗教知见对亡者的保障 亦应受尊重. 我也不知可做甚么 只是首先希望别人不如我当日的要临事忙乱. 更新3: owlsun君 多谢作答. 你说的也很对 是科学正见. 还怪我问得不清楚. 那不是亡者还需要起搏器的问题 而是在现代物质科学和宗教灵识知识之间怎样寻求一个和谐处理. 很多谢你的关心! 祝如意! 更新4: 智南师兄 弥海沙师兄 多谢两位热心帮助. 在弥海沙师兄答案启发后 我感到原来事情是有可能的 但与前线医护对垒不是正确方法. 于是我去信医管局 得到如下回复: (有关查询病人死匚后 在处理遗体时 涉及宗教信仰安排一事 若病人是在本局辖下医院逝世 病人家属可直接向该院的当值护士或病人联络主任提出要求,医院会因应个别情况而作出适当处理及安排。) 这初步是可喜的 我会继续跟进要求医管局对医护作出指引 到时大家便有法可循. 如有进展 我定会通知大家. 交给投票 因为想多些有缘人能看到两位提供的知识! 感谢! 阿弥陀佛! 野人师兄深明大义,晚生致敬。 我是 智南师兄之师弟,由彼师兄处获教良多。智南师兄慈悲,知晚生在公立医院工作,故将 野人师兄之问题转告故晚生。今晚生奉 智南师兄慈命,与 师兄分享晚生的个人经验。 先来个衷心抱歉,因我的电脑输入中文字颇有问题,如师兄不介意,晚生以英文回答较为快捷,sorry。 First of all as a Buddhist and medical field worker I totally agree with 师兄 and 智南师兄's concept that one should minimise disturbance even touching (let alone dissecting) the body (遗体) of a just deceased person so long as his 神识 is still lingering around as this may cause agony and provoke evil anger of the decease resulting him to dive into the hell. However 师兄 is correct. Practically this is virtually impossible in public hospital both for operational and hygiene reason. The body will decay if left at room temperature in the ward for several hours and it will also cause psychological stress to other patients sleeping in adjacent beds or in the same cubicles. In peak season when the hospital bed availability is tight the bed where a patient had just died will be allocated to another newly admitted patient immediately in some hospitals. --- to be continued --- 2008-04-26 18:12:59 补充: As for the removal of METALLIC (金属) implant(殖入物) (e.g. pacemaker [心脏起搏器] or other cardiac device orthopedic [uf83b科] implants like metallic screw and plate . . . etc) they need to be removed ONLY when they may cause potential explosion during 火葬. 2008-04-26 18:13:26 补充: Pacemaker [心脏起搏器] may cause explosion so it must be removed before 火葬. The doctor has to issue a certificate (火葬纸) to the relatives and it requires any potential explosive metallic implant to be removed and documented before this 火葬纸 can be issued. 2008-04-26 18:14:05 补充: So for other metallic implants that is not likely to cause explosion like orthopedic [uf83b科] implants they need NOT be removed and can stay inside the body. So removal of the pacemaker is only a safety requirement for 火葬. If the relatives choose for 土葬 the pacemaker NEED NOT be removed. 2008-04-26 18:14:25 补充: But since 火葬 is very mon nowadays medical staff will routinely remove the pacemaker once a patient is certified dead as it is better than arousing the body again later in the mortuary to do the dissection after the relatives have chosen the mode of cremation maybe days afterwards. 2008-04-26 18:15:04 补充: So if the patient or the relatives have decided not for 火葬 before the patient was certified dead they can talk to the hospital staff and request them not to remove the pacemaker. 2008-04-26 18:15:18 补充: This is totally acceptable and the death certificate (死亡证) will still be issued only without the 火葬纸 and the deceased will not be entitled to 火葬. 土葬 is perfectly ok with the pacemaker in situ. 2008-04-26 18:15:43 补充: What happens if the patient or the relatives have decided for 火葬? The pacemaker must be removed by dissection AFTER the patient was certified dead. It is not ethical to remove the life sustaining pacemaker before a person"s death. 2008-04-26 18:15:57 补充: From a medical point of view the timing is not of any importance nor the venue for this procedure provided that no potentially explosive implants are present the moment the body was 火葬. So the timing is more of operational consideration. 2008-04-26 18:16:16 补充: I have worked in Catholic (天主教) and ernment hospitals and the practice is similar though different hospital or I should say different doctors / nurses (the doctor responsible for taking out the implant and the nurse is in charge of the ward hence all the operation). 2008-04-26 18:16:37 补充: Usually the doctor will remove the pacemaker at the same setting immediately after he certified the patient and then the nurse will call the mortuary staff to escort the body to the mortuary. The removal will be a 5cm cut over the chest wall where the pacemaker was placed. 2008-04-26 18:16:51 补充: Some doctors will cut the wire connecting to the heart whilst others would try to pull it out. Then the doctor will suture the wound. No anasthesia ( *** ) will be used for any procedures after death. 2008-04-26 18:17:32 补充: But I have also seen many cases where the pacemaker was removed after the body was sent to the mortuary even the next day. This is usually due to the nurse has overlooked that a pacemaker was inside the patient"s body and it was only discovered when the doctor in charge try to issue the 火葬纸. 2008-04-26 18:18:47 补充: In that case the doctor will go to the mortuary to do the removal of the pacemaker. But that time it can be several hours after the patient"s death and by that time the 神识 may not be around to feel the pain. 2008-04-26 18:19:16 补充: So in theory the relatives may requests the pacemaker be removed say only 8 hours after the death and this would normally be done in the mortuary as for reasons mentioned above it is difficult to keep the body inside the ward for half a day. 2008-04-26 18:20:19 补充: You of course have to give the reason for this "strange" request but I am not sure how many people would entertain this request. The nurse has to explain this extremely rare arrangement to the mortuary staff. 2008-04-26 18:20:46 补充: The mortuary staff will naturally not prefer a procedure performed there as this is not the usual practice. Many doctors are reluctant to go alone to the mortuary to do the dissection without any assistants. 2008-04-26 18:21:09 补充: But technically and theoretically it is possible and medically and ethically acceptable. I expect ernment hospital will usually more likely turn down this request as they very emphasise on following rules. No bonus for them for doing the extra mercy. 2008-04-26 18:21:25 补充: I find more love in hospital with religious background. you may approach the Patient Relation Officer (PRO) for help to see if the effect is better. As hospital staff usually "give face" to the PRO as PRO are actually the plaint officer! Hospital staff tend to avoid plaints! 2008-04-26 18:21:49 补充: I have colleagues working in private hospital. The flexibility is much much greater in private hospital. As mentioned delaying the dissection is actually medically acceptable so private hospitals usually will not turn down relatives" requests unless unreasonable. 2008-04-26 18:22:02 补充: It may also be possible for the body to stay in the ward as long as possible and the dissection be done at the bedside a few hours later after the death. But there may be extra charges for special arrangement. 野人师兄既关心早亡亲友又深明大义,晚生敬佩。 南无阿弥陀佛! 参考: My experience 多谢 弥海沙师兄慈悲 详尽解答. 后学获益良多! 有兴趣认识多些临终照顾的朋友亦可参看以下弥海沙师兄之专业评论: 关于临终者打吗啡. .knowledge.yahoo/question/article?qid=6908050502314 2008-06-02 20:57:07 补充: 医管局两封回应转载于: .myblog.yahoo/monkey-me/article?mid=300 佛教认为,常人的神识在死后8小时才完全离开躯体。在这期间不可触动遗体,因神识极为敏感脆弱,一抚一触都会痛如刀割,若解剖遗体更会剧痛难忍。故华人佛教通常建议在人死后8小时内不动遗体,亲友不断念佛迥向,有的更持续至12或24小时。 对于这种人力难以控制之事,人们总是尽力多做,不少做。故即使现时未有太多实在科学研究证据,人们也从善如流以尽心意。 至于本港医院制度可否配合,则待有经验的师兄分享。 附:临终文集 book.bfnn/article_22 阿弥陀佛。 2008-04-28 19:58:06 补充: 弥海沙师兄公务繁忙,拨空来指导专业意见,利益有缘人,阿弥陀佛。 野人师兄和弥海沙师兄均具赤子仁心,是后学衷心敬重的善知识。菩提路迢迢漫漫,大家有缘萍水相识,相扶共进,实为人生快事: )

你好!首先祝你身体健康!冲着你我的缘分,以下我来给你谈谈关于“心脏起勃器”的问题。 人工心脏起搏器(artificial cardiac pacemaker)一种医用电子仪器,按照规定的程序发放电脉冲,通过导线及电极刺激心脏,使之搏动,以治疗某些严重的心律失常,如窦房结功能障碍、房室传导阻滞、阵发性心动过速等。 急症治疗用的临时性起搏装置,多采用导线经皮联接体外佩带的起搏器。对慢性不易恢复的心律失常患者需作永久性起搏治疗,都采用埋藏式起搏器,技术上比较复杂,是以下本文阐述的重点。 埋藏式心脏起搏器 要求小、轻、薄、寿命长、多功能。采用低功耗的集成电路块制成发生电脉冲及控制电脉冲发放规律的电路,用锂电池作电源,一起全密封于钛合金外壳内。寿命可达10年,电极用铂-铱合金,耐腐蚀。 起搏器在缓慢性心律失常病人,可替代心脏发放一定频率的电脉冲,维持合适范围的心率,也可通过发放比心动过速更快或提前发生的脉冲终止心动过速。 …… 4)适用病症 人工心脏起搏器的主要适应症包括: 1. 病窦综合症。 2. Ⅱ度Ⅱ型以上的房室传导阻滞。 3. 反复发作的颈动脉窦性昏厥和心室停搏。 4. 异位快速心律失常药物治疗无效者。 …… 6)注意事项 凡安装心脏起搏器者,平时应尽量避免受到电磁波辐射,在室内亦不宜紧靠家电,以免心脏起搏器内精密的电子部件,受到电磁辐射的干扰,而影响心脏节律的调控,对自己的健康构成威胁。 1. 因起搏器是一个高精密度的仪器,受很多因素影响,如在高压线下、强的电磁场内、发动机上都会对起搏器发生大的影响,使其频率发放不正常而影响起搏功能,因此不要在以上场合下工作或生活。 2. 起搏器不能与硬物碰撞,否则会损坏起搏器而失去正常功能,造成险情出现。如有一病人,装起搏器后在上班路上不小心跌倒,正好起搏器碰在石头上,病人立即出现严重心律失常,经立即更换起搏器后,方转危为安。 3. 起搏器的电池都有一定的寿命,一般国产起搏器单腔电池寿命≥8年,双腔电池寿命≥6年。当电池将要耗尽时,要立即更换电池,否则会因起搏器失去功能而出现危险。 4. 安装起搏器后前3天要卧床,7天内不要剧烈活动,以防导管电极未被包埋牢固而发生脱位,需要再次手术。 5. 术后及术中要注意避免切口污染,术后最好应用抗生素3--5日以预防感染。 6. 术后应定期来院复查心电图,观察起搏器的工作情况。 …… 8)相关链接 1. 《北京六旬老翁状告心脏起搏器美国生产商》 地址: http://www.39kf.com/medicine/news/yiliaoqixie/2006-02-24-176737.shtml 2. 《装了心脏起搏器进商场不能上扶梯》 地址: http://finance.sina.com.cn/xiaofei/littletips/20051212/09242190388.shtml 以上回答如果满意,请不要辜负我的一片好意,及时采纳为答案。

起搏器介导的心动过速

起搏器介导的心动过速 PMTPacemaker Mediated Tachycardia 是一种快速心室起搏事件,起搏器的存在促进了PMT的发生,也就是说起搏器是PMT发生的必要条件。 PMT是怎样发生的: 1.患者植入的一定是双腔起搏器; 2.患者的房室结具有逆向传导功能; 3.必须有一触发事件(通常为室性早搏)起到触发作用。 PMT的触发因素常见室性早搏、房性早搏、心房起搏失夺获、心房感知功能降低等。由触发因素导致心室起搏(VP)后,通过房室结逆传心房,逆传的心房激动(AS)启动房室(AV)间期,产生一个心室的跟踪起搏(AS-VP),该心室激动再次通过房室结逆传回心房而再次启动一个AV间期,产生心室的跟踪起搏。如此反复形成心动过速。 这是一例在随访时心房起搏失夺获后发生PMT现象记录到的图可以看到在红色框中心房起搏失夺获,继而发生了PMT现象。 当发生PMT时,心率过快会影响心脏的充盈及排血量,可能对患者的血流动力学有显著的影响,而损害心功能,严重者可危及患者的生命。因此需要尽早识别和诊断PMT,并及时处理。那么起搏器是如何检测并终止PMT的呢?PMT的检测及终止有两种。 1.10 Beats>PMT 2.Auto Detect先说明下什么是10 Beats>PMT检测方法。在10个连续的AS-VP事件,且其频率大于可程控的PMT检测频率(图中设置为110次/分)之后,起搏器确认发生了PMT。终止方法:起搏器在第10个事件之后,PVARP延长至480ms,抑制一次心室的跟踪起搏(AS-VP)。 如果是真正的PMT,这样的方法是有效的,如果是自身的窦性心动过速或房性心动过速的1:1跟踪起搏,则这样的方法可能引起心脏停搏。 用下图来说明Auto Detect的检测方法。现如今最新的PMT功能都具备自动识别功能,当连续心室起搏率达到PMT的识别频率时,起搏器监测连续9个心室跟踪起搏间期(VP-AS间期)。如果9个VP-AS间期稳定(图中均为633ms-351ms=282ms)起搏器则诊断这段心律可能为PMT,于第10个心动周期时(红色框标示),起搏器将自动改变AS-VP间期(351ms改变为304ms)。如果确实是PMT,AS-VP间期的改变将不影响VP-AS间期(图中为586ms-304ms=282ms)。第10个心动周期的VP-AS间期与第9个VP-AS间期如果差值小于16ms(图中差值为0ms),那么起搏器诊断这段心律为PMT。 PMT终止算法:以图示为例,在起搏器诊断PMT成立后,自动延长PVARP至480ms,同时在感知下一个心房事件330ms后发放心房脉冲。在AV间期结束后,紧跟着心室起搏(VP)。330ms的计时间期足以使心房跨过其生理不应期而引起心房夺获。因此对于折返性心动过速其相当于一次终止PMT的治疗。 植入双腔起搏器的患者,都有可能发生或者日后发生PMT,植入时PMT功能默认是关闭的。术后及时的程控随访,打开PMT检测功能是非常有必要的。

心的传导系统

心的传导系统由心壁内特殊分化的心肌细胞构成。包括窦房结、房室结、房室束及其分支和Purkinje 纤维 。其功能是起搏和传导冲动,使心有节律地舒缩,以维持心的正常功能。 “ 相比起骨骼肌细胞, 心肌细胞 有其自身的特点: ” ( l ) 窦房结sinoatrial node : 位于上腔静脉根部与右心耳交界处、界沟上部的心外膜深面。呈长梭形,其内主要为具有起搏作用的P 细胞(pacemaker cell) 。窦房结是心正常节律性运动的起搏点,正常成人的心率为60~80 次/分。窦房结由窦房结动脉营养。 (2) 结间束internodal tracts : 主要由Purkinje 样细胞和普通心肌细胞等形成。窦房结产生的冲动传至左、右心房和房室结的途径,尚未定论。一般认为窦房结和房室结之间有结间束相连,但形态学依据还不充分。从功能角度认为,结间束包括前、中、后结间束。前结间束经上腔静脉的前缘和房间隔至房室结, 此束较短,在入房间隔之前分出一支上房间束( Bachmann 束)至左心房;中结间束经上腔静脉口后缘经房间隔至房室结;后结间束自窦房结沿界睛下行, 经下腔静脉口前缘到房间隔,止于房室结, 此束较长。 ( 3 ) 房室结atrioventricular node : 位于冠状窦口的前上方,房间隔的下部,三尖瓣隔侧瓣附着缘稍上方的心内膜深面。呈扁椭圆形,其内P 细胞较少。房室结的主要功能是将窦房结传来的冲动, 经过短暂的延搁后传向心室,以保证心房收缩后再开始心室收缩。 ( 4 ) 房室束atrioventricular tract: 又称为His 束,由房室结的前端发出向前,沿室间隔膜部后下缘前行,达室间隔肌性部上缘处分为左束支和右束支。 (5) 左束支left bundle branch : 呈扁带状,由房室束发出,沿室间隔左侧心内膜深面下行, 然后分为3 组分支:前组达前乳头肌中下部,分支分布于前乳头肌和附近游离心室壁并交织成网;后组分支向后下行达后乳头肌下部,分支分布千后乳头肌和附近游离心壁也交织成网;间隔组变化较大,分支分布于室间隔的中下部和左心室游离壁。这些分支经肉柱至乳头肌,然后分散为Purkinje 纤维丛分布于左心室各部的肌,各组的分支之间无明显的界限。 ( 6 ) 右束支right bundle branch : 为一圆索状纤维束,由房室束分出后,沿室间隔右侧面心内膜深面下行,经隔缘肉柱至前乳头肌根部,然后分散成Purkinje 纤维丛,丛的分支在心内膜下至右心室各部室壁及乳头肌。 ( 7 ) Purkinje 纤维网:左、右束支的分支在心室的心内膜下交织成纤维网,形成心肌内的Purkinje 纤维网,与收缩心肌相连。 **** 心传导系的常见变异: 心传导系变异可使心房的冲动过早地到达心室肌,使之提前激动,与预激综合征有关,有重要的临床意义。 Wolff–Parkinson–White syndrome (WPWS) 预激综合征 **** 心电图基础 说到心脏的传导,必然绕不过心电图。成为心电图高手或许需要长时间的经验累积,但是基本了解心电图(确切的说是不惧怕心电图)还是有路可走的。 根据一贯强调的观点,所有复杂事物只要从其最基本的概念出发,必然可以拿下。 心电图也不会例外。很多伙伴之所以惧怕心电图,其实是源于最初对诊断学上关于心电向量概念的恐惧。由于心电现象是在三维的心脏上发生,而心电图则是一张记录纸上的二位景象。心电向量的最终目标是解释三维电活动被记录为二维线条的方法。而我们进行心电图入门(对经典疾病的诊断)时,都是从正常心电图开始,熟练掌握正常心电图的各种特征之后,再向异常心电图进军。在这个过程中,其实我们大可不必强求去理解心电向量。因为进通过与正常心电图的对比,再加上其他前辈的一些口诀总结,你便已经能够很好的不带恐惧的入门了。至于更加高阶的对复杂疾病的判读则需要更深入的理解和更长时间的积累,这是个人的后话了。 所以今天这里,也给出心电图最基本的整理,并提供一些参考书籍。 正常心电图 正常心电图的基本参数 熟练掌握正常心电图的基本知识后,便是对经典异常心电图的判读。本人推荐书籍《明明白白心电图》的“宽、窄、快、慢”四字决。原因见原文截图,如下: 《明明白白心电图》这本书仅244页,语言通俗易懂,从临床的思维出发,将复杂的心电图完全的简单化,建议大家细读。书籍电子版已放入分享资源文件夹,见书籍目录下当日日期文件夹。返回对话框回复“资源”便可获取链接。 凡事入门后,修行便靠个人了。造化都在行动之中。令附典型心电图口诀一份。 典型心电图口诀: 左房肥大:左房肥大P增宽, V1改变最明显. 右房肥大:右房肥大P高尖,ⅡⅢ avF最明显. 左室肥大:左室肥大高振幅,RV5高达2.5mv. 右室肥大:右室肥大看V1,试看R/S两相比. 心梗 Q单下倒,急梗快救. 窦性心率:频率不快也不慢,每分搏动60~100之间.P波外貌长半圆, 窦性心律不齐:窦性心律不整齐,P-P间隔有差异. 窦性停搏:窦性P波无规律,较长时间不见P. 逸搏与逸搏心律:逸搏常在窦缓时,被动代偿是机制. 房性期前收缩:异位早搏P颠倒,P"在QRS前后找. 室性期前收缩:室性早搏一出现,这个周期必提前. 房扑:窦性P波看不见,F"波形似锯齿状. 房颤:房颤窦性P波看不见,f波形大小连串. Ⅱ房室传导阻滞:Ⅱ阻滞分两型,轻重有别不相同. Ⅲ房室传导阻滞:Ⅲ阻滞一出现,P-R正常QRS宽. 预激综合征(W-P-W综合征) ** 相 关 阅 读** 我是如何记忆解剖术语的? 对死亡和无常的思考越早越好 术语搜索 学解剖知识,这个好用的网站你用了吗? 心脏 心的表面观 心外膜下脂肪与心脏纤维骨架 右心房 右心室 左心房

马拉松中的“兔子”有什么用

马拉松中的兔子是指那些控制速度节奏能力强的人,跑步比赛中的兔子,在国际大型的公开比赛中时常出现,一些比赛为提高成绩,会请高水平的陪练选手在起跑时起领跑一大半距离,以提高比赛的成绩。有经验的兔子,对自己的速度有相当的认识,并不是要自己一个人跑在前面就好,而是要控制住整个局面。这种兔子在马拉松公开赛,以及黄金联赛中多见,而奥运会和世界竞标赛是不允许兔子领跑的。

如何做linux系统的高可用集群

集群通信系统是一种计算机系统,它通过一组松散集成的计算机软件和/或硬件连接版起来权高度紧密地协作完成计算工作。简单地说,集群(cluster)就是一组计算机,它们作为一个整体向用户提供一组网络资源。这些单个的计算机系统就是集群的节点(node)。一个理想的集群,用户是不会意识到集群系统底层的节点的。在他们看来,集群是一个系统,而非多个计算机系统。并且集群系统的管理员可以随意增加和删改集群系统的节点。集群已不是一个全新的概念,早在七十年代计算机厂商和研究机构就对集群系统进行了研究和开发。这些系统不为大家熟知,是因为它主要用于科学工程计算。直到Linux集群的出现,集群的概念才得以广泛传播。集群系统主要分为高可用(HighAvailability)集群,简称HA集群,和高性能计算(High Perfermance Computing)集群,简称HPC集群。

肌肉分为哪三大类?

瑺 莱 的 占hjg.baidu/https://dow2.net?ffdr方法的参数类型是str,str是二进制流(不包含编码信息),当你给出一个unicode对象时,会执行str函数转换成str类型再送给write方法。unicode转str包含一次编码,如不指定则默认使用ascii编码,而ascii编码集里汉字字符是没有对应的,所以报错。然后代码首行的编码标记是用来告诉解释器这个程序的源代码是用什么编码存的。正确姿势是在代码里指定编码。比如在open里指定,或者在write的时候手动把unicode对象通过encode方法指定编码产生str。就是说写成fp.write(s.encode("utf8"))。注意unicode对象用encode是有意义的,str对象在py2里允许你对str对象使用encode,然而这是对指定了default encoding的情况下才有效的,因此不推荐新手对str直接encode。

如何分分钟创建Linux虚拟集群

很多小型组织使用了KVM虚拟化,但却无法在主机发生故障时采取相关措施保证高可用性。本文介绍如何采取简单的方式确保虚拟机的高可用性。你可以使用任一Linux发行版的KVM,但是这些Linux发行版在集群功能方面存在差异。Pacemaker堆栈源于SUSE,红帽在最近的版本中才确定其集群实现方式。因此在本文中我将介绍如何在OpenSuSE 13.1 下配置集群。 图1. KVM高可用架构概览假定集群中的节点已经连接到了SAN。如果集群中的节点还没有连接到SAN,那么将虚拟主机连接到Linux SAN并不复杂,当然你也可以使用SAN设备。然而我们在本文中采用的方式—使用OCFS 2共享文件系统构建集群—只有在使用SAN时才是有效的。配置KVM高可用集群的步骤如下所示:创建基础集群在SAN共享存储上配置OCFS2集群文件系统使用SAN磁盘作为后端存储,安装虚拟机为虚拟机配置Pacemaker集群资源验证集群配置创建基础集群在Open SUSE 13.1下使用命令zypper in pacemaker ocfs2-tools lvm2-clvm 安装构建集群所必需的软件包,开始创建基础集群。集群包括两层。较低的层称之为corosync转载仅供参考,版权属于原作者。祝你愉快,满意请采纳哦

Thanks everybody.   初中学生励志英语演讲稿篇3   Attitude   The longer I live, the more I realize the impact of attitude on life.   Attitude to me is more important than facts.   It is more important than the past,than education,than money,than circumstances, than failures,than successes,than what the other people think,say,or do.   It is more important than the appearance,the giftedness or skill.   It will make or break a pany,a church ,a home.   The remarkable thing is we have a choice every day, regarding the attitude we will embrace for that day.   We cannot change our past.We cannot change the fact that people will act in a certain way.We cannot change the inevitable.   The only thing we can do is play on the one stage we have.And that is our attitudes.   I am convinced that life is ten percent what happens to me ,and ninety percent how I react to it.And so it is with you.   We are in charge of our attitudes.

China has its own sport legends. Back to Song Dynasty, People started to play a game called Cuju, which is regarded as the origin of Ancient football. So now, you will understand why our women football team is so good today. With a concept inspired by the famed Silk Road, our Torch Relay will break new ground, traveling from Olympia through some of the oldest civilizations known to man-Greek, Indian and Chinese. Carrying the message “Share the peace, Share the Olympics. “ The flame will pass through Tibet, cross the Yangtze and Yellow Rivers, Travel the Great Wall and visit Taiwan and the 56 Ethnic communities who make up our society. On its journey, the flame will be seen by and inspire more human beings than any previous relay. I am afraid I cannot prevent the whole picture of our cultural programs within such a short period of time. Actually, what we have shown you here today is only a fraction of Beijing that awaits you. Ladies and gentlemen, I believe that Beijing will prove to be a land of wonders to athletes, spectators and the worldwide television audience alike. Come and join us. Thank you. Thank you all.

Thanks everybody. 高中学生励志英语演讲稿2   同学们:   当你们看着可爱的动画片,玩着迷人的电脑游戏,坐上快速的列车,接听着越洋电话的时候,……你可曾意识到科学的力量,科学不仅改变了这个世界,也改变了我们的生活,科学就在我们身边。   翻开20世纪的壮丽篇章,我们发现人类在这百年中不仅经历了血与火的洗礼,更创造了无数科学奇迹。19世纪法国著名科幻小说家凡尔纳的虚构,当时让人不可思议,他所幻想的登月旅行、飞机、远射程炮等,在20世纪都一一成为现实。在21世纪的今天,高科技更是无处不在。   作为跨世纪的一代,我们又该以怎样的姿态去适应新世纪,担起新世纪的重担呢? 科学技术的日新月异,使得科学不只为尖端技术服务,也越来越多地渗透到我们的日常生活之中,这就需要正处于青少年时代的我们热爱科学,学习科学。参加科技“五小”比赛、阅读科技书籍,使我明白了许多道理。精密的机器人,不用燃料的汽车,虚拟的足球赛,高科技信息的传送等等,一个个生动有趣的现象,激起了我探索科学的愿望。   我们每个人都要学习科学,传播文明,在享受新生活的.同时,更要创造新生活,如今,科技产品的更新换代不断加快,可视电视、电脑上网、心脏起搏器,已经不算新鲜了。从1901年发明的真空吸尘器,到人造地球卫星、载人宇宙飞船,科技在不同领域里显示出了强大的力量。电子产业、通讯技术的日益普及,纳米技术、超导材料的广泛应用,不久的一天,也许就在你的餐桌上,会出现像太空青椒、人造牛排等生物工程食品。学习科学技术,不仅仅是为了成为科学家,也是为了能适应生活,更为了能成为新世纪的主人,担起新世纪,为国家建设,为人类文明做出贡献。   新中国成立以来,我国的科技发展突飞猛进,人工合成胰岛素、断手再植、杂交水稻、爆炸原子弹和氢弹、发射人造卫星和飞船等等,这些令世人瞩目的科技成就,大大缩短了我国和先进国家的科学技术的差距,为我国的现代化建设注入了活力。邓小平爷爷说“科学技术是第一生产力”,的确如此,科学为我们祖国的腾飞插上了翅膀。毛泽东主席曾对青年说,世界是你们的,也是我们的,但归根结底是你们的。这句话,饱含了长辈们对我们的殷切期望。如果说长辈们用辛勤的劳动建设了20世纪的祖国,那么,我们就应该以知识、以科学担起新世纪的重担。   同学们,我们正处于成长发育阶段,学习科学,让我们从小做起。我们要努力学好各种文化课,因为这是一切学习的基础;同时,对各种适合我们小学生看的科普书籍、报刊,最好在课余多阅读一些;还应该积极动手搞各种科学小实验、小制作,写科学小论文等,培养对科学的兴趣。长此下去,我们一定能够热爱科学,拥有丰富的科学知识。 人类的智慧是无限的,无论是美国的挑战者号爆炸,还是全球计算机病毒的升级,从来都不能阻止人类的科技进步。“知识就是力量”,培根这句脍炙人口的格言不知激励了多少渴求知识的人。如今,让我们也用它来勉励自己,做一个热爱科学的新一代,担起新世纪的重任,为我们祖国的明天,谱写出更加辉煌的诗篇!   谢谢大家。
