心室复极稳定性的心电学指标及其评价
Electrocardiographic indicators of ventricular repolarization stability and their evaluation
摘要
Abstract
Myocardial action potential results from the regular opening and closing of ion channels on the cell membrane.Different from depolarization,the repolarization of ventricular muscle goes through a long period,influenced by many factors and thus performs poor stability.Ventricular repolarization is an important stage in electrical activities of the heart.Even micro interference in the process may trigger ar-rhythmia.Electrocardiogram is the most commonly used and convenient method of detecting the incon-sistency of ventricular repolarization.Several electrocardiographic indicators such as corrected QT inter-val,QTd,QT/RR,Tp-Te,Tp-Te /QT,QRS-T angle and VG are frequently used to evaluate the stabili-ty of ventricular repolarization.These indicators are used extensively in the risk evaluation of various dis-eases clinically.This paper reviews on the research progress of the above indicators.关键词
