Premature ventricular complexes (PVCs) are usually benign, and commonly only severely symptomatic patients are treated. In the literature, frequent PVCs have been reported to cause ventricular dysfunction, which may improve after PVC treatment. PVCs can also worsen the prognosis in patients with structural heart disease. Catheter PVC ablation is often the treatment of choice considering the high success rates. Ventricular dysfunction due to frequent PVCs is not always easy to identify as patients can be asymptomatic and the interpretation of imaging tests may be challenging in the presence of frequent PVCs. Treatment of patients with mild ventricular dysfunction is still a matter of debate.
室性早搏（PVCs）通常是良性的，一般仅对症状严重的患者进行治疗。文献报道，频发室性早搏可导致心室功能障碍，经治疗后可能改善。室性早搏也会使结构性心脏病患者的预后恶化。考虑到高成功率，导管消融术常为首选治疗方法。由于患者可能无症状，且在频发室性早搏的情况下，影像学检查结果的解读可能具有挑战性，因此频发室性早搏所致的心室功能障碍并不总是易于识别。轻度心室功能障碍患者的治疗仍存在争议。
