综合国内207例HCM的心电图表现。最常见的改变是病理性Q波,其它依次为非特异性ST-T改变、左室肥厚、心律失常及传导阻滞。各类传导阻滞中以不完全性右束支阻滞为多见,无1例左束支阻滞。有1例罕见的HCM合并间歇性左后分支阻滞,另1例为出生后即有症状、心电图示Ⅲ度房室传导阻滞为主的先天性HCM。作者报道17例中占首位的心电图表现为非特异性ST-T改变。而病理性Q波为次。1/3患者电轴中度以上左偏,4/5患者QTC延长。有1例进展为猝死的梗阻型HCM,生前一年半内Q波宽度、深度多变,而且Q波一度消失,当晕厥发作时描记的心电图中病理性Q波重又出现。这种现象迄今似未见诸文献报道。
Integrated national HCM of 207 cases of ECG performance. The most common changes were pathological Q waves, followed by non-specific ST-T changes, left ventricular hypertrophy, arrhythmias, and conduction block. Various types of block in the right bundle branch block is more common, no cases of left bundle branch block. One case of uncommon HCM with intermittent left posterior branch block, and the other one was symptomatic after birth, electrocardiogram third degree atrioventricular block-based congenital HCM. The authors report that the top of the 17 cases of ECG showed non-specific ST-T changes. The pathological Q wave is secondary. 1/3 patients with left axis deviation above the middle, 4/5 patients QTC extension. There was 1 case of obstructive HCM that progressed to sudden death. The Q wave width and depth varied a year and a half before the birth, and the Q wave disappeared at one time. When the syncope happened, the pathological Q wave appeared again in the electrocardiogram. So far this phenomenon seems to have not been reported in the literature.
