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.

126例心房颤动合并长R—R间期患者的动态心电图分析

目的采用动态心电图分析心房颤动合并长R—R间期（〉1．5s）、逸搏及逸搏心律患者是否存在房室阻滞。方法对126例心房颤动患者进行24h动态心电图检查，根据患者记录的生活日志，按长R—R间期、逸搏及逸搏心律出现的时间是否与睡眠有关，把患者分为A（睡眠有关组）、B（睡眠无关组）两组。结果A组发生长R—R间期1．5～2．0s，〉2．0s及逸搏及逸搏心律人平均数分别为（26．02±6．03）、（7．39±1．05）、（6．90±1．28）；B组发生长R—R间期1．5—2．0s，〉2．0s及逸搏及逸搏心律人平均数分别为（203．05±41．01）、（35．48±7．52）、（28．10±6．25）；B组明显多于A组（P〈0．01）。结论房颤伴长R—R间期、逸搏及逸搏心律与睡眠有关时，此现象非病理性房室阻滞；而房颤伴长R—R间期、逸搏及逸搏心律与睡眠无关时，应视为病理性房室阻滞。

12导联动态心电图与平板运动试验对冠心病的诊断价值

目的:探讨12导联动态心电图(AECG)与平板运动试验(TET)对冠心病的诊断价值.方法:选择64例可疑冠心病患者,在行冠状动脉造影(CAG)检查前行AECG与TET检查.以CAG结果作为标准,分析TET与AECG两种检查方法对冠心病的诊断价值,以及两者联合使用对冠心病的诊断价值.结果:AECG检出冠脉病变的敏感性为66%,特异性58%;TET敏感性78%,特异性41%;AECG和TET并联使用时敏感性为91%,较单项AECG、TET试验有显著提高(P ＜ 0.05),串联使用特异性88%,较单项AECG、TET试验有显著提高(P ＜ 0.05).结论:单独行TET或AECG检查对冠心病诊断的敏感性和特异性相对较低,两者联合诊断可明显提高上述两项指标.     

HRV及QTd在急性心肌梗死早期溶栓治疗中的意义

目的研究急性心肌梗死（AMI）早期溶栓治疗中心率变异性（HRV）及溶栓治疗前后QT离散度（QTd）变化的意义,并探讨HRV与QTd的相关性。方法对AMI患者早期溶栓再通组、未通组及AMI未溶栓组在起病14d后行24h动态心电图检查及心率变异性（HRV）分析,同时对所有组别进行治疗前后QTd变化对比,观察QTd与HRV的相关性。结果溶检成功组HRV时域分析指标及频域分析指标较溶栓失败组和非溶栓组均显著提高（P〈0．01）,溶栓失败组与非溶栓组所有HRV分析指标差异均无统计学意义（P〉0．05）。溶检成功组、溶栓失败组与非溶栓组的QTd在治疗前均明显增大,在治疗后溶检成功组QTd显著减dx（P〈0．01）,而溶栓失败组与非溶栓组QTd恢复速度显著慢于溶栓成功组,HRV与QTd在急性心肌梗死（AUI）早期溶栓治疗中有显著相关性。结论急性心肌梗死早期溶栓能显著提高患者HRV,显著减小QTd,改善心肌电稳定性及自主神经功能,减少致命性心律失常等事件的发生,从而改善急性心肌梗死患者的预后。
