心室复极异常与恶性室性心律失常的关系已日益受到人们的重视。近年来,对心室复极异常与恶性室性心律失常的临床联系及离子基础的研究有了长足的进展,本文阐述了心室复极异常的心电图表现、离子基础及其与恶性室性心律失常之间的关系。1心室复极异常的心电图表现心电图上QRS-ST The relationship between ventricular repolarization abnormality and malignant ventricular arrhythmia has been paid more and more attention. In recent years, great progress has been made in the study of the clinical connection and ion base of ventricular repolarization abnormalities and malignant ventricular arrhythmias. This article describes the ECG manifestation of ventricular repolarization abnormality, ion base and its relationship with malignant ventricular arrhythmia Relationship between. 1 Ventricular repolarization abnormal ECG presentation QRS-ST
