本文对35例冠心病患者进行了QT离散度与室性心动过速（VT）诱发的关系的研究。患者的平均年龄为66 ± 9岁（± SD），平均左心室射血分数为0.36 ± 0.14。在6例可通过程控心室刺激诱导的持续性单形性VT患者中，QT离散度显著大于29例不可诱导VT的患者（126 +/- 35 vs 67 +/- 25 ms，p 120 ms），可诱导持续性单形性VT，无患者QT离散度
This study examines the relation between QT dispersion and the inducibility of ventricular tachycardia (VT) in 35 consecutive patients with coronary artery disease who underwent electrophysiologic testing for evaluation of nonsustained VT. The mean age of the patients was 66 +/- 9 years (+/- SD) and the mean left ventricular ejection fraction was 0.36 +/- 0.14. In 6 patients in whom sustained, monomorphic VT was inducible by programmed ventricular stimulation, QT dispersion was significantly greater than in the 29 patients in whom VT was not inducible (126 +/- 35 vs 67 +/- 25 ms, p 120 ms had inducible sustained monomorphic VT, and no patient who had a QT dispersion
