冠心病持续性室性心动过速患者的Q-T离散度

Q-T dispersion in coronary artery disease patients with sustained ventricular tachycardia

为评价Q-T_d对冠心病患者发生室性心动过速的预测价值,观察18例冠心病持续性室性心动过速患者和20例对照组的Q-T_d。结果显示持续型室性心动过速组Q_(Td)(104±28ms)明显大于对照组(61±19ms,P<0.01)。表明Q-T_d的增加可作为预测室性心动过速发生的重要指标。

Authors observed Q-Td in 18 coronary artery disease (CHD) patients with ventricular tachycardia (VT) and 20 controls in order to assess predictive value of Q-Td in CHD with VT. Results showed that Q-Td were greater in VT group (104±28ms) than that in control group ( 61±19ms, P < 0. 01 ) which indicated that Q-Td might serve as an important indicator in predicting forthcoming VT.
