体表心电图的Q-T间期为心室除极及复极的总时间,正常人的Q-T间期随心率、年龄、心脏疾病及药物而变动,但一般不超过480ms。长QT综合征(Iong QT Syndrome,LQTS)是以体表心电图QT间期延长,多型性室性心动过速,心脏性晕
The Q-T interval of the body surface electrocardiogram is the total time of ventricular depolarization and repolarization. The normal Q-T interval varies with heart rate, age, heart disease and medication, but generally does not exceed 480ms. Long QT syndrome (Iong QT Syndrome, LQTS) is the body surface electrocardiogram QT prolongation, multimodality ventricular tachycardia, cardiac halo
