摘　　要：目的　探讨分支型室速 (FVT)的机制。方法　就 10例FVT的心电图特征、机制以及治疗作一探讨。结果　 10例中 8例呈完全性右束支传导阻滞 (CRBBB) ,2例呈不完全性右束支传导阻滞 (ICRBBB) ;额面电轴LAD者中 8例 ,RAD者 2例。 5例经射频消融治疗、3例用异搏定治疗、1例利多卡因治疗、1例FVT发作时心率仅 6 8/min ,拟为自律性增高的逸博心律 ,阿托品使发作消失。 1例有文氏传出阻滞后 ,该 2例似不能以折返机制解释 ,余近返机制可能性为大。讨论　支型室速多为折返机制 ,但不能排除自律性增高。Objective\ To investigate the possible mechanism of fasicular ventricular tachycardia(FVT).Method\ Ten cases of FVT with different ECG manifestion and treatment were analysed.Of the 10 cases,8 exhibited LAD and 2 RAD.Ablation was performed on 5 cases;3 cases were treated with verapamil,1 case with lidocaine;in another case ventricular rate was 68bpm,and ventricular escape rhythm was considered.One case exhibited Wenckenbach conduction.Reentry seemed unlikely in these 2 cases.Result\ Reentry was the basis in most cases of FVT,but in some,enhanced automaticity could be the underlying mechanism.
