Ventricular inhibited demand pacemakers (VVI) were implanted in 27 patients with complete A-V block and pacemaker arrhythmias were analyzed by Holter system ambulatory electrocardiograms and conventional electrocardiograms. With Holter ECG, 13 patients showed myopotential inhibition, 5 patients had sensing failure and premature ventricular contractions (PVC) were observed in all patients. On the contrary, myopotential inhibition and sensing failure were not detected by conventional ECG and the detection rate of PVC was only 30%. The transient recovery of A-V conduction was observed in 14 of 27 patients with Holter ECG, but was not detected by conventional ECG. The Holter system ambulatory electrocardiogram clearly demonstrated the complex cardiac arrhythmias. Therefore, it is useful for monitoring arrhythmias caused by VVI pacemakers.
为27例完全性房室传导阻滞患者植入心室抑制按需型起搏器（VVI），并通过动态心电图系统和常规心电图分析起搏器心律失常。在动态心电图检查中，13例患者出现肌电位抑制，5例患者存在感知功能障碍，所有患者均观察到室性早搏（PVC）。相反，常规心电图未检测到肌电位抑制和感知功能障碍，PVC的检出率仅为30%。在27例患者中，动态心电图检查发现14例患者出现房室传导的短暂恢复，而常规心电图未检测到。动态心电图系统清楚地显示了复杂的心律失常。因此，它对于监测VVI起搏器引起的心律失常很有用。
