冠心病患者Q──Tc与心室晚电位关系探讨

Relations between Q-Tc period and ventricular late potentials in coronary heartdiseases

分别用踏车运动试验的Ｑ－Ｔｃ间期和晚电位对６０例正常人和６０例冠心病患者进行检测，结果发现它们对正常人的假阳性率极低，对冠心病患者的阳性率均较高，有较大的临床应用价值，而心室晚电位的检测尤为方便，对活动不便的患者更为实用。

Q-Tc period after bicycle ergometer exercise test and ventricular late potentials of 60 patients with coro-nary heart diseases and 60 normal suuects as control were studied.The results show that examination rate is veryhigh with both methods in patients and is low in normal subjects. Therefore both these two methods are valuable forclinical use. Especially due to the convienece of implemention of late potentials,it is recommended for patients withdiffculty to move.
