摘　　要：目的:探讨二维超声心动图(2DE)结合心电图(ECG)诊断心尖部肥厚型心肌病(AHCM)的准确率,并与2DE和ECG单独诊断的准确率比较。方法:60例患者,30例心尖部肥厚型心肌病,另30例心电图显示ST-T改变,行左室造影或心脏磁共振检查。结果:单独ECG诊断AHCM的敏感性高(接近100%),但特异性低(约27%);单独2DE诊断AHCM敏感性为93%,特异性为100%;两者结合诊断AHCM能提高2DE诊断的敏感性。结论:利用二维超声心动图结合心电图能提高对心尖部肥厚型心肌病诊断的准确率,便于临床推广。Objective：To explore the two dimensional echocardiography （2DE） and electrocardiography （ECG） accuracy of the diagnosis of apical hypertrophic cardio myopathy （AHCM）. Methods： 60 patients with abnormal ST segment and T wave in their electrocardiograms were divided into two groups, apical hypertrophic cardiomyopathy and control subjects. The patients also underwent left ventricular angiography or magnetic resonance imaging. Results： There were the high sensitivity （close to 100%） by ECG diagnosing AHCM separately, but low specificity （27%）. The sensitivity of separate 2DE diagnosing AHCM was 93% and specificity was 100%. Combination of 2DE and ECG parameters augmented the sensitivity and specificity for analyzing AHCM. Conclusion： The results suggest that the diagnosis of apical hypertrophic cardiomyopathy can be improved by combining two dimensional echocardiography with electrocardiography, to facilitate clinical practice.
