起搏器植入术后T波记忆现象1例

T wave memory after a pacemaker implantation:a case report

1病例资料患者,男,76岁。因＂胸痛3h＂入院。入院前3h因外出散步时突感胸痛,持续不可缓解,由急救车送入我院急诊科。入院体检：体温35.8℃,脉搏32次/min,呼吸23次/min,血压100/60 mmHg（1mmHg=0.133kPa）,意识模糊,体型略胖,双肺呼吸音粗,未闻及干湿啰音,心界不大,心律齐,心率32次/min,腹软,无压痛及反跳痛,肝脾肋下未触及,生理反射存在,病理反射未引出。

Cardiac memory is a unique phenomenon of electrical remodeling characterized by marked diffuse T-wave inversions（TWI）that can be misdiagnosed as myocardial ischemia.Misdiagnosis of cardiac memory can be easily result in unnecessary diagnostic investigations or therapeutic interventions.We report a case of T wave memory after a pacemaker implantation in acute inferior myocardial infarction.
