摘要

T波电交替(T wave alternation,TWA)是指在规整心律时,体表心电图上T波形态、极性和振幅逐搏交替变化。因其发生机制尚不明确,诊断标准不够统一,临床检测不易发现,限制了TWA在临床的广泛应用。本文结合多年文献,就TWA的发展历程、诊断标准、发生机制、临床应用进行综合概述,为今后的研究提供了新的临床探讨方向。

Abstract

T wave alternation (TWA) refers to the alternation of T wave shape, polarity and amplitude on the surface electrocardiogram during the regular rhythm. Since the mechanism of its occurrence is still unclear,the diagnostic criteria of TWA is not uniform and the clinical tests are not easy to be found, which limit the application of TWA in the clinical practice. In this paper, referring to many literature, we make a comprehensive review on the development history, diagnostic criteria, mechanism and clinical application of TWA, providing a new direction for clinical research in future.
