本文报道7例阵发性完全性房室传导阻滞伴心室静止的临床和心电图分析,其中5例为冠心病,2例为急性病毒性心肌炎。心电图特征为连续出现多个未能下传的窦性P波而无逸搏心律出现,临床有阿-斯征发作。作者认为除了房室交接处性心动过速前向传导阻滞形成的假性Ⅲ度房室传导阻滞外,二束支阻滞伴频率依赖性第三束支阻滞以及快-慢综合征也能形成这种情况。此外,在原有房室Ⅲ度房传导阻滞的情况下,逸搏心律可以突然不出现。对于次级起搏不出现的原因,作者试作一探讨。
This article reports seven cases of paroxysmal paroxysmal atrioventricular block with ventricular static and ECG analysis, of which 5 cases of coronary heart disease, 2 cases of acute viral myocarditis. ECG characteristics for the continuous emergence of multiple failed to pass down the sinus P wave without pacemaker rhythm appears, there are clinical Alzheimer’s attack. The authors believe that in addition to atrioventricular junctional tachycardia before the conduction block of the formation of pseudo Ⅲ degree atrioventricular block, the two bundle branch block with frequency dependent third bundle branch block and fast-slow syndrome Can also form this situation. In addition, in the case of the original atrioventricular nocturnal block, escape rhythm can suddenly not occur. The reasons for the secondary pacing does not appear, the author try to explore.
