The benign or severe nature of a ventricular extrasystole depends on a number of parameters which involve the pathophysiological mechanism of the extrasystole: re-entry, exaggerated normal or abnormal automatism and therefore the presence or absence of an underlying cardiac disease. The prognosis depends directly on the morphology, the number and the characteristics of the arrhythmia. Various investigations are often necessary to evaluate this prognosis, including 24 hour Holter monitoring, stress test and electrophysiological investigations.
室性期前收缩的良性或严重性取决于多个参数，这些参数涉及期前收缩的病理生理机制：折返、正常或异常自律性增强，因此也取决于是否存在潜在的心脏病。预后直接取决于心律失常的形态、数量和特征。通常需要进行各种检查来评估这种预后，包括24小时动态心电图监测、负荷试验和电生理检查。
