Caused by the defect of a Lem-Dynacor pacemaker, a critical diminution of the period time till 20 ms developed. Fortunately, ventricular fibrillation did not occur because of diminution of the impulse amplitude beyond the threshold value of ventricular stimulation. Recognition of the defect with the ECG is possible if considered. It is easy to confuse with overlapping of alternating current.
由于Lem-Dynacor起搏器的缺陷,出现了直至20毫秒的关键周期时间缩短。幸运的是,由于脉冲幅度减小至低于心室刺激阈值,未发生心室颤动。如果加以考虑,通过心电图识别该缺陷是可能的。它很容易与交流电重叠相混淆。
