A 45-year-old man was found to have an abnormal myocardial perfusion scan. He was asymptomatic, with no chest pain, breathlessness or palpitations. Clinical examination was unremarkable. The 12-lead electrocardiography (ECG) showed increased QRS voltage in leads V3-V6, and deep T-wave inversions noted in leads V3-V6, with an absence of septal Q waves. These ECG features were characteristic of apical variant hypertrophic cardiomyopathy (HCM). He underwent a coronary angiogram that revealed normal coronary arteries, and a left ventriculogram which showed apical HCM. Transthoracic echocardiography further confirmed the diagnosis. No drug therapy was instituted as he was asymptomatic. Apical HCM is discussed.
一名45岁男性的心肌灌注扫描结果异常。他没有症状，无胸痛、呼吸急促或心悸。临床检查无异常。12导联心电图（ECG）显示V3-V6导联QRS电压增高，V3-V6导联T波深倒置，无间隔Q波。这些心电图特征是心尖部变异型肥厚型心肌病（HCM）的典型表现。他接受了冠状动脉造影，结果显示冠状动脉正常，左心室造影显示心尖部HCM。经胸超声心动图进一步证实了诊断。由于他没有症状，未进行药物治疗。本文对心尖部HCM进行了讨论。
