本文对急性心肌梗塞合并室性心动过速72例进行分析。结果表明:早搏型室速60%为成对型室早触发,而 R on T 型室早仅占9%。早搏指数与易损指数对预示室速与室颤均不敏感。加速室性自主节律可合并早搏型室速,部分可能为早搏型室速伴有异位起搏点2∶1传出阻滞,也可两者并存。顶后:早搏型室速若为持续性且合并室壁瘤者室速的复发倾向很大,这组患者长期服用有效的抗心律失常药物是必要的。
In this paper, 72 cases of acute myocardial infarction with ventricular tachycardia were analyzed. The results showed that: premature beat-type ventricular tachycardia 60% for the early trigger, while R on T-shaped chamber as early as only 9%. Premature beats index and vulnerability index showed no sensitivity to ventricular tachycardia and ventricular fibrillation. Accelerate ventricular spontaneous rhythm can be combined premature beat VT, some may be premature ventricular VT accompanied by ectopic pacemaker 2: 1 block, but also the two co-exist. Top: If premature ventricular tachycardia is persistent and the ventricular tachycardia is associated with a high recurrence of ventricular tachycardia, long-term use of effective antiarrhythmic drugs is necessary for this group of patients.
