T波电交替(TWA)是指T波振幅随心脏搏动发生周期性改变,是致死性室性心律失常的预测指标。据报道非缺血性心脏病(NIHD)患者在TWA阳性时~(123)I-MIBG心肌显像异常,而扩张型
T wave alternation (TWA) refers to the T wave amplitude changes periodically with the heart beat, is a predictive indicator of lethal ventricular arrhythmia. It is reported that non-ischemic heart disease (NIHD) patients with TWA-positive ~ (123) I-MIBG myocardial imaging anomalies, and dilated
