Ventricular tachycardia is now diagnosed frequently in patients with organic heart disease. Although ventricular tachycardia was first demonstrated electrocardiographically 75 years ago, the natural history, fundamental mechanisms, and optimal management have remained elusive. Early observers commented on the rarity of occurrence and poor prognosis associated with this arrhythmia, yet with time, some patients with ventricular tachycardia were reported to survive for prolonged periods. Because of the sporadic nature of the arrhythmia and its variable prognosis, assessment of the efficacy of therapies has been difficult. A wide variety of treatments has been advocated with enthusiasm, but only a few have been consistently reported to be effective. Citation of historical data to claim benefit from new treatments should be viewed with caution.
室性心动过速目前在器质性心脏病患者中经常被诊断出来。尽管室性心动过速早在75年前就通过心电图得到了证实，但其自然病程、基本机制和最佳治疗方法仍然难以捉摸。早期的观察家评论了这种心律失常的罕见性和与之相关的不良预后，但随着时间的推移，有报道称一些室性心动过速患者能长期存活。由于这种心律失常的散发性及其预后的多变性，评估治疗效果一直很困难。人们热情地提倡了各种各样的治疗方法，但只有少数几种一直被报道是有效的。引用历史数据来声称从新治疗方法中获益时应谨慎看待。
