室性心动过速是一种严重且常导致死亡的心脏电紊乱,体表心电图对之很难作出诊断。室性心动过速的典型心电图标准是房室分离及快速室率伴畸形 QRS 波;虽然统计学上有力支持这是室性心动过速,然而也见于阵发性房室连接处性心动过速伴束支传导 Ventricular tachycardia is a serious and often leading to death of cardiac electrical disorder, the body surface ECG is difficult to make a diagnosis. The typical ECG standard for ventricular tachyarrhythmias is atrioventricular separation and rapid ventricular rate with QRF; with statistically significant support for ventricular tachycardia, it is also found in paroxysmal atrioventricular tachycardia With bundle branch conduction
