A 43-year-old man was admitted to our hospital presenting with seizures and syncope. He had a history of a cold with a fever of 39°C occurring three days earlier. Electrocardiography (ECG) showed complete atrioventricular block (AV block) with a maximum pause of 32 seconds, for which temporary pacing was performed. Echocardiography showed mild hypertrophy of the left ventricle (LV) with a normal ejection fraction of 61%. Coronary angiography showed normal coronary arteries. Then, an endomyocardial biopsy was performed, the results of which indicated a diagnosis of acute myocarditis. After admission, the complete atrioventricular block disappeared together with normalization of the LV wall thickness.
一名43岁男性因癫痫发作和晕厥入院。他三天前有过感冒发热，体温达39°C的病史。心电图（ECG）显示完全性房室传导阻滞（AV阻滞），最长停顿时间为32秒，为此进行了临时起搏。超声心动图显示左心室（LV）轻度肥厚，射血分数正常，为61%。冠状动脉造影显示冠状动脉正常。随后进行了心内膜心肌活检，结果表明诊断为急性心肌炎。入院后，完全性房室传导阻滞消失，左心室壁厚度恢复正常。
