Somberg,C.C.etal AmHeart J 1986,111(6):1175～1176 临床医生治疗室性心律失常时,必须懂得异位搏动和心肌易损性的相互关系。频发室性异位搏动和心肌易损性是产生心脏猝死的二个决定因素,后者是发生致命性室性心律失常的基础。一些频发室性异位搏动的病人,由于没有器质性心肌病变和心肌易损性以及可供形成室速的异常通道,所以心脏猝死的危险性很小,即使心律失常有时相当严重,抗心律失常的治疗仍然不是必须的。但是有症状的患者,需要减少异位搏动的治疗,以消除心悸症状,减轻病人烦恼。在另一方面,有些病人偶见异位搏动,例如广泛前壁心肌梗塞的病人,哪怕仅有

Frequent ventricular ectopic beats and myocardial vulnerability are two determinants of sudden cardiac death, the latter being the basis for fatal ventricular arrhythmias. Some patients with frequent ventricular ectopic beats due to no organic heart disease and myocardial vulnerability and the formation of abnormal ventricular tachycardias, so the risk of sudden cardiac death is very small, even if the arrhythmia is sometimes very serious, anti Arrhythmia treatment is still not necessary. However, symptomatic patients need to reduce the treatment of ectopic beats to eliminate symptoms of palpitations and reduce patient troubles. On the other hand, some patients sometimes occasionally ectopic beat, such as patients with extensive anterior myocardial infarction, even if only
