本文报告1例肥厚型心肌病患者发生猝死,死因与异搏停所致的心律失常有关。病例报告:患者男性,62岁,因心力衰竭和严重的呼吸困难于1983年1月入院。以前曾因劳力性呼吸困难和阵发性心房颤动发作住过院。检查结果如下:在快速心律失常发作间期的心电图正常;心胸比例为0.50;M型和切面超声心动图证实为肥厚型心肌病:左室腔缩小(舒张末期径和收缩末期径分别为44和27毫米)、左室后壁和室间隔增厚(分别为20.5和16毫米);室间隔与游离壁的比率为1.28。心导管检查表明肺动脉压正常,休息时无左室流出道梗阻。心血管造影显示喷血分数为0.74,冠状动脉远端有弥漫性病损。本次入院之前数月,
This article reports a sudden death in patients with hypertrophic cardiomyopathy, the cause of death and verapamil caused by arrhythmia. Case Report: Male patient, aged 62, was admitted to hospital in January 1983 due to heart failure and severe dyspnea. Previously had hospitalized for exertional dyspnea and paroxysmal atrial fibrillation. The examination results were as follows: normal electrocardiogram during tachyarrhythmia episode; cardiothoracic proportion of 0.50; hypertrophic cardiomyopathy confirmed by M-mode and section echocardiography: left ventricular systole (end-diastolic diameter and end-systolic diameter of 44 and 27 mm), thickening of the left ventricular posterior wall and interventricular septum (20.5 and 16 mm, respectively), and a ratio of ventricular septum to free wall of 1.28. Cardiac catheterization showed normal pulmonary pressure, resting without left ventricular outflow tract obstruction. Cardiovascular angiography showed a fractional spurt of 0.74 with diffuse lesions distal to the coronary arteries. A few months before this admission,
