Abstract

A coved-type electrocardiogram (ECG) change in Brugada syndrome is suggested to be the result of abnormally delayed depolarization over the right ventricular outflow tract; however, ischemia of the conus branch of the right coronary artery presents the same ECG change. A 63-year-old man with a history of myocardial infarction demonstrated a transient coved-type ECG change during catheter ablation of ventricular tachycardia. The ECG change appeared during left ventricular mapping without any chest symptoms, and recovered spontaneously. A pilsicainide test was negative and a coved-type ECG did not appear during the perioperative or follow-up period.

摘要

Brugada综合征中的穹窿型心电图（ECG）改变被认为是右心室流出道异常延迟去极化的结果；然而，右冠状动脉圆锥支缺血也会出现相同的ECG改变。一名有心肌梗死病史的63岁男性在室性心动过速导管消融期间出现了短暂的穹窿型ECG改变。这种ECG改变在左心室标测期间出现，没有任何胸部症状，并自发恢复。吡西卡尼试验为阴性，围手术期或随访期间未出现穹窿型ECG。
