METHODS: The first patient was a 68-year-old woman complaining of recurrent chest tightness persisting for more than 3 years. The second was a 59-year-old man complaining of spasmodic chest tightness persisting for more than 2 years. The third was a 55-year-old woman complaining of recurrent chest pain persisting for 4 mo. In all three cases, GNTs were observed several years prior to apical cardiac hypertrophy after other causes of T-wave inversion were ruled out.
CONCLUSIONS: Electrophysiological abnormalities of AHCM appear earlier than structural abnormalities, confirming the early predictive value of ECG for AHCM.
方法:首例患者是一名68岁女性,主诉复发性胸闷持续3年以上。第二位是一名59岁的男子,抱怨痉挛性胸闷持续超过2年。第三名是一名55岁的妇女,抱怨反复发作的胸痛持续了4个月。在这三种情况下,在排除了其他T波倒置原因后,在心尖心肌肥大之前几年观察到了GNT。
结论:AHCM的电生理异常比结构异常更早出现,证实心电图对AHCM的早期预测价值。
