Q-T波峰间期(即QTa间期)、T波顶峰后宽度(TaTe间期)反映了心室除、复极电生理过程,与自主神经功能及室性心律失常密切相关。本文介绍了QTa间期、TaTe间期及其计算方法、影响因素和意义,并综述了QTa间期、TaTe间期与心血管病之间的关系。
Q-T peak interval (ie, QTa interval), T peak width (TaTe interval) reflects the ventricular extrapolation, bipolar electrophysiological processes, and autonomic nervous function and ventricular arrhythmias are closely related. This article describes the QTa interval, TaTe interval and its calculation methods, influencing factors and significance, and summed up the QTa interval, TaTe interval and the relationship between cardiovascular disease.
