分支性搏动与室性心动过速的诊断与治疗（附2例报告）

DIAGNOSIS AND TREATMENT OF FASCICULAR VENTRICULAR TACHYCARDIA

本文报告２例无明显器质性心脏病、心电图示ＱＲＳ时限＜０．１２秒、呈不完全性束支传导阻滞伴电轴偏移的分支性室性心动过速患者。室速经静注异搏定和心律平能中止发作，而对利多卡因静注反应差。并就此类心律失常的诊断与治疗作了简要讨论。

2 cases are reported,which had fascicular ventricular tachycardia but no demonstrable heart disease exhibiting a pattern of incomplete bundle branch block with cardiac electric axis edviation,QRS complex wave duration <0.12 second during tachycardia.The tachycardia could be terminated by intravenous injection of verapamil and propafenone,but the response to lidocaine was poor.The diagnosis and treatment of these specific types of ventricular tachycardia are discussed in brief.
