Premature ventricular contractions occurring in asymptomatic patients without heart disease are benign and need not be treated. Beta blockers may be used for symptomatic patients. Antiarrhythmic therapy for patients after myocardial infarction is controversial; authors of recent studies have tended to discourage this therapy. Patients with malignant arrhythmias--who have been resuscitated from cardiac arrest caused by ventricular ectopy or who have ventricular tachycardia-associated syncope--should be referred for electrophysiologic testing and individualized therapy.
无症状且无心脏病的患者出现室性早搏是良性的，无需治疗。β受体阻滞剂可用于有症状的患者。心肌梗死后患者的抗心律失常治疗存在争议；近期研究的作者倾向于不鼓励这种治疗。患有恶性心律失常的患者——即因室性异位心律导致心脏骤停后复苏或患有室性心动过速相关晕厥的患者——应转诊进行电生理检查并接受个体化治疗。
