VT may be observed to accompany a wide variety of heart diseases and occasionally no heart disease at all. The efficacy of drug therapy is dependent on antiarrhythmic effects and the mechanism underlying the patient's VT. Conventional antiarrhythmic agents appear to be effective in no more than one third of patients, but a substantial number of other potentially useful antiarrhythmic agents exist. Unfortunately, their effectiveness in treating sustained VT for the most part must still be proved. Other agents such as amiodarone appear effective, but ways to predict which patients will benefit remain unknown. Invasive and noninvasive techniques exist for assessing therapeutic efficacy, but determination of which is more appropriate awaits a wider experience and more direct comparison.
室性心动过速（VT）可见于多种心脏疾病，偶尔也可在无心脏病的情况下出现。药物治疗的疗效取决于抗心律失常作用以及患者室性心动过速的潜在机制。传统抗心律失常药物似乎对不超过三分之一的患者有效，但存在大量其他可能有用的抗心律失常药物。不幸的是，它们在治疗持续性室性心动过速方面的有效性在很大程度上仍有待证实。其他药物如胺碘酮似乎有效，但预测哪些患者将从中获益的方法仍然未知。存在有创和无创技术用于评估治疗效果，但确定哪种技术更合适尚需更多经验和更直接的比较。
