T波电交替现象可见于长QT综合征、急性心肌缺血、变异型心绞痛、心脏性猝死以及电解质紊乱等.它在预测室性心律失常方面与电生理检查具有高度的一致性,是恶性室性心律失常和心脏性猝死的独立预测指标,是评定恶性心律失常以及心脏性猝死的可信、实用的技术之一.现在,T波电交替已经成为了一种廉价、方便的非侵入式心电检测方法.现综述T波电交替的研究背景、产生机制、检测方法及其临床研究,并简要分析了T波电交替的研究方向和发展前景.

T-wave alternans (TWA) can be found in long QT syndrome, acute myocardial ischemia, variant angina pectoris, sudden cardiac death, electrolyte turbulence, and others. It has a high rate of consistency when used with an electro-physiological examination in detecting ventricular arrhythmia. It is also an independent prognosticating index and a reliable, practical technology accessing to malignant ventricular arrhythmia and sudden cardiac death. TWA represents today an inexpensive, convenient and non-invasive testing modality for electrocardiogram. The research background, mechanism of the onset, detection and its application in clinical investigations of TWA were reviewed in this paper. The study focus and the perspective of TWA were also briefly discussed.
