心电图Q—T间期代表心室激动及恢复所需要的除极化及复极化时间,很多因素可使Q—T延长,由于心肌细胞弥慢性传导减慢及心肌细胞复极时间的差异,有利于折反现象的产生,因而易致室性心动过速。1966年Desser-tenne等把在Q—T延长基础上出现的室速命名为扭转型室速。几年来我们常遇到各种原因所致的Q—T延长,由于原因不同,治疗方法
ECG Q-T on behalf of the ventricular activation and recovery required for the depolarization and repolarization time, many factors can make Q-T prolongation, due to slow myocardial cardiomyocytes slow and ventricular repolarization differences in time, there are Avoids the phenomenon of folding phenomenon, which is easy to cause ventricular tachycardia. In 1966, Desser-tenne et al. Named the ventricular tachycardia, which is based on the Q-T extension, as torsional VT. Over the past few years we often encounter a variety of reasons for Q-T prolongation, due to different reasons, treatment
