希氏束电图在缓慢性心律失常的应用（附10例报告）

我院于1987年6月开展了希氏束电图对缓慢性心律失常的检查,3例Ⅲ度房室传导阻滞(Ⅲ°AVB),7例病窦综合征(以下简称病窦),并同时做了心内窦房结功能电生理检查,报告如下。 1 资料与方法     

文氏型窦房传导阻滞,Ⅰ度房室传导阻滞伴交替性左前,左后分支传导阻滞

患者女性,76岁,因持续性剑突下疼痛11h伴恶心、呕吐入院.心电图示Ⅱ、Ⅲ、aVF导联ST段抬高,伴ST-T动态变化.血清心肌酶CPK22.6μmol·s~(-1)/L,GOT3367nmol·s~(-1)/L,LDH4.8μmol·s~(-1)/L,CPK-MB19.3%,LDH_(1)0.515,LDH_(2)0.281.诊断为急性膈面心肌梗塞.入院当日摸拟Ⅲ导联心电监护时连续记录的心电图(附图)示上行P_1—P_5的P-P间距长短交替,分别为0.72和1.08s,长间歇短于2个短间歇之和,为3:2文氏型窦房传出阻滞,根据基本周期=文氏周期等长间歇÷(R-R间     

临床中非特异性ST—T改变对疾病诊断的价值

临床中心电图ST-T改变对某些疾病诊断及鉴别诊断具有非常重要的实用价值．缺血性sT-T改变，如冠状动脉供血不足引起的缺血性改变．虽有其特征、定位分布及动态改变等特点．一般对诊断冠脉供血不足有一的诊断价值．但非特异性．缺血型S了段降低，其中有水平型、下垂型、弓背型及下陷型几种．其他还     

多层传导阻滞

患者女性,76岁,因持续性胸骨后疼痛10h,服速效救心丸无效于1992年3月18日23:00急诊入院.体检:BP120/80mmHg(16/llkPa).心界不大,心率66次/min,律齐,心音低钝,三尖瓣区可闻及Ⅱ级收缩期杂音.二肺呼吸音清.腹软,肝、脾未及.双下肢无水肿.实验室检查:血常规正常,CPK1332U/L,SGOT4984.3nmol·s~(-1),LDH 17.65 umol·S~(-1)/L,LDH_(1)43%,LDH_(2)30%,LDH_(3)13%,LDH_(4)14%.常规心电图检查(附图 A)示     

运动试验诱发T波高尖伴U波倒置一例

运动试验诱发Ｔ波高尖伴Ｕ波倒置一例安徽省安庆市第一人民医院内科刘斌患者，男性，６０岁。近年来反复发作胸闷、心前区疼痛伴大汗淋漓，每次发作时间持续约１分种，含服硝酸甘油片可以缓解，多于劳累时发作，多次静息心电图检查均属正常。今年四月曾因上述症状住院治疗...     

126例心房颤动合并长R-R间期患者的动态心电图分析

Objective To analyze the relationship between atrial fibrillation complicating long R-R interval, escape beat and escape heart rhythm and pathological atrioventricular block by dynamic electrocardiography (DCG). Methods 126 patients with atrial fibrillation were divided into group A (being related to sleep) and group B (being not related to sleep) according to the factor whether long R-R interval, escape beat and escape heart rhythm relevant to sleep. All were detected by DCG for 24 hours. Results The cases with1.5～2.0 s long R-R interval, more than 2.0s long R-R interval, escape beat and escape heart rhythm were (26.02±6.03), (7.39±1.05 ) and (6.90±1.28)in group A and (203.05±41.01), (35.48±7.52), (28.10±6.25) in group B respectively. The cases of group B were markedly more than those in group A. Conclusion Those atrial fibrillation complicating long R-R interval, escape bbeat and escape heart rhythm were related to sleep could not be deemed as pathological atrioventricular block, while those were not related to sleep could be considered pathological atrioventricular block.     

一项关于儿童持续性交界区反复性心动过速临床特点和预后的多中心研究

目的:探讨儿童持续性交界区反复性心动过速(PJRT)的临床特点、自然史和最佳治疗方法。方法和结果:85例符合PJRT心电图诊断标准的患者被纳入该多中心回顾性研究。确诊年龄范围为从出生到20岁(中位年龄3个月),随访时间为0.1～26年(中位时间8.2年)。85例患者中24例(28%)有充血性心
