摘要
3例陈旧性心肌梗塞室壁瘤并发室性心动过速(VT)的患者,接受了心脏电生理检查。希氏束电图或食道导联心电图证实A(P)波与V(QRS)波分离,V波前无H波,符合室性心动过速的诊断。在检查中,将电极导管插至右心室内,电刺激右心室可终止室性心动过速。室速发作时,用普鲁卡因胺静脉注射治疗效果好;随访0.5～4年,胺碘酮、心律平、奎尼丁能预防VT再发作。
The electrophysiologic procedures were performed in three
patients with old myocardial infarction and aneurysm complicating ventricular
tachycardia.The His bundle electrogram(HBE)and the electrocardiogram of
esophageal lead showed A(P)waves and V(QRS)waves were dissociated.
There were no H waves before the V waves on HBE during the attack of
tachycardia.The ventricular tachycardia were determined by stimulating the
apex of right ventricular wall using a cardiac electrode-catheter.The tachy-
cardia responsed well for procainamide intravenously.The agents of aminoda-
rone,quinidine,propafenone can prevent recurrence of ventricular tachycar-
dia in the period of 0.5 to 4 years follow-up.
