伴有室性心律失常的冠心病患者与无室性异位搏动的类似冠心病患者相比,具有较高的死亡危险性。纽约健康保险计划(HIP)研究结果显示,在1小时的基础监护中发现有复杂性室性早搏(指连续二个或二个以上、Ron T 现象、二联律、多源性早搏)者其冠心病猝死的危险性特别高(这里猝死的定义是患者在保持平时的健康状况下、无任何新的心肌梗塞症状和体征而于数分或数十分钟内的死亡)。猝死与复杂的心律失常有关,提示表现为室性异位搏动的心电不稳定性会导致致死性心室颤动的发生。但是有些研究者发现,在冠心病患者24小时
Patients with coronary heart disease associated with ventricular arrhythmias have a higher risk of dying than patients with similar coronary disease without ventricular ectopic beats. The results of the New York Health Insurance Plan (HIP) showed that patients with complex premature ventricular contractions (two consecutive or more than two consecutive, Ron T, diplopia, and multi-source preeclampsia) were found in 1-hour basic care The risk of sudden death from coronary heart disease is particularly high (here, sudden death is defined as death in minutes or tens of minutes without any new signs and symptoms of myocardial infarction while maintaining usual health). Sudden death and complex arrhythmia, suggesting that the performance of ventricular ectopic beating instability will lead to the occurrence of lethal ventricular fibrillation. However, some researchers found that patients with coronary heart disease 24 hours
