We investigated the clinical and electrophysiological features of monomorphic ventricular tachycardia (MVT) with different initiation patterns in patients with implantable cardioverter defibrillator to assess whether there is a relationship between the initiation patterns of sustained MVT and clinical characteristics, and the efficacy of antiarrhythmic and electrical therapy. Fifty-five stored IECGs in twenty-two patients with MVT were evaluated. All MVT episodes were classified as initiating with ventricular premature beats (non-sudden onset MVT) or without ventricular ectopy preceding tachycardia (sudden onset MVT). Non-sudden onset MVT was characterized by shorter tachycardia cycle length (CL) and required higher shock energy for termination. Sudden onset MVT was precipitated by shortening of the sinus CL before tachycardia and was more common with relatively better preserved systolic function.
我们研究了植入式心脏复律除颤器患者中不同起始模式的单形性室性心动过速（MVT）的临床和电生理特征，以评估持续性MVT的起始模式与临床特征之间是否存在关联，以及抗心律失常和电疗法的疗效。对22例MVT患者的55份存储的植入式心电图（IECG）进行了评估。所有MVT发作被分类为起始于心室早搏（非突然发作MVT）或心动过速前无室性异位搏动（突然发作MVT）。非突然发作MVT的特征是心动过速周期长度（CL）较短，终止所需的电击能量较高。突然发作MVT是由心动过速前窦性CL缩短诱发的，在收缩功能相对保留较好的情况下更常见。
