Macroscopic T-wave alternans (TWA) is the beat-to-beat variation in the amplitude or shape of the T wave on a surface electrocardiogram (ECG) and known to be a harbinger of impending malignant ventricular arrhythmias such as polymorphic ventricular tachycardia. We herein report a case with hepatic encephalopathy, who developed TWA, followed by polymorphic ventricular tachycardia.
宏观 T 波电交替（TWA）是体表心电图（ECG）上 T 波幅度或形态的逐搏变化，已知是恶性室性心律失常（如多形性室性心动过速）即将发生的先兆。本文报告了一例肝性脑病患者，该患者出现 TWA 后，继而发生多形性室性心动过速。
