Electroconvulsive therapy (ECT), regarded as safe, well tolerated, and one of the most effective treatments for depression, is used frequently in patients with underlying coronary artery disease. ECT has been associated with ST depression and arrhythmias probably due to increased myocardial demand in patients with coronary artery disease. This report describes a case of transient new T-wave inversions in precordial leads V2 and V3 and flattening of T waves in leads III, V3, V4, V5, and a VF after two courses of ECT in a patient with minimal cardiac risk factors, normal echocardiogram, and normal pre-ECT electrocardiogram (ECG). These T-wave changes may represent increased sympathetic activity induced by ECT. Previous prospective studies of 26 and 21 patients undergoing serial ECT found only one new T-wave inversion and no pathologic Q waves on serial ECGs, suggesting that this is a rare finding.
电休克疗法（ECT）被认为是安全、耐受性良好且治疗抑郁症最有效的方法之一，常用于患有潜在冠状动脉疾病的患者。ECT与ST段压低和心律失常有关，这可能是由于冠状动脉疾病患者心肌需求增加所致。本报告描述了一例患者，该患者心脏危险因素极小、超声心动图正常且ECT前心电图（ECG）正常，在接受两个疗程的ECT后，胸前导联V2和V3出现短暂性新的T波倒置，导联III、V3、V4、V5和VF的T波平坦。这些T波变化可能代表ECT引起的交感神经活动增加。之前对26例和21例接受系列ECT的患者进行的前瞻性研究发现，系列心电图上仅出现一例新的T波倒置，且无病理性Q波，表明这是一个罕见的发现。
