A clinico-electrocardiographic analysis of 25 cases with atrial tachycardia and atrioventricular block was conducted. Confirmation was established of the connection between the development of atrial tachycardia with atrioventricular block and changes in the myocardium, circulatory insufficiency, acute coronary failure and toxicosis with cardiac glucosides. Such signs of atrial tachycardia with atrioventricular block as the rate of atrial rhythm of 150 to 250 per minute, the possibility of fluctuations in the P-P interval, the presence of an isoelectric PP segment, and atrioventricular block of various degree were found to be of the highest diagnostic value. It is presumed that the development of atrioventricular block in atrial tachycardia is linked with changes in the conducting system of the heart.
对25例房性心动过速伴房室传导阻滞患者进行了临床心电图分析。证实了房性心动过速伴房室传导阻滞的发生与心肌变化、循环功能不全、急性冠状动脉功能衰竭以及洋地黄中毒之间的联系。发现房性心动过速伴房室传导阻滞的一些征象，如心房率为每分钟150至250次、P-P间期有波动的可能性、等电位P-P段的存在以及不同程度的房室传导阻滞，具有最高的诊断价值。据推测，房性心动过速时房室传导阻滞的发生与心脏传导系统的变化有关。
