A 28-year-old man presented with progressive fatigue. Physical examination and ECG revealed severe sinus bradycardia. Echocardiography showed features of noncompaction cardiomyopathy and moderate aortic valve regurgitation. We hypothesized that the chronic volume overload exaggerated by prolonged diastole due to the bradycardia resulted in heart failure and noncompaction cardiomyopathy look-alike features. After implantation of an AAI pacemaker, his symptoms and signs of cardiomyopathy were fully recovered.
一位 28 岁男性因进行性疲劳就诊。体格检查和心电图显示严重的窦性心动过缓。超声心动图显示非致密性心肌病和中度主动脉瓣反流的特征。我们推测,由于心动过缓导致舒张期延长引起的慢性容量超负荷加重导致心力衰竭和非致密性心肌病样特征。植入 AAI 起搏器后,他的心肌病症状和体征完全恢复。
