摘要
目的观察肥厚型心肌病的心电图和超声心动图特点。方法对临床确诊的32例肥厚型心肌病患者心电图、超声心动图资料进行回顾性分析。结果所有患者心电图均有异常,以ST-T改变、左室高电压和异常Q波为多见。Q波深度与室间隔厚度、ST压低深度与心尖部室壁厚度均呈正相关,而T波深度与心尖部室壁厚度无相关性,但与心尖部和室间隔的室壁厚度差呈正相关,左房大小与平均室壁厚度呈正相关。结论在肥厚型心肌病中,心电图和超声心动图中的许多异常指标具有相关性,两者结合可提高本病诊断率。
Objective To analyse the changes of electrocardiogram （ECG） and echocardiography （UCG） in 32 patients with hypertrophic cardiomypathy. Methods 32 cases with hypertrophic cardiomypathy were reviewed based on the clinical, ECG and UCG data. Results All cases had abnormal ECG. The most frequent abnormal was ST segment and T wave changes. The second was left ventricle high voltage and the third was abnormal Q wave. The depth of Q wave had linear correlation with the thickness of interventricular septum （IVS）. And the depth of ST segment depression had linear correlation with the thickness of apical ventricular wall. But the depth of negative T wave was not related with the thickness of apical （AP） ventricular wall, and it had linear correlation with the difference in thickness of ventricular wall between AP and IVS. The left atrial size had linear correlation with the average thickness of the left ventricular wall. Conclusions Many abnormalities of ECG and UCG are in relation to each other in hypertrophic cardiomypathy. The combination of ECG and UCG is important for the diagnosis of hypertrophic cardiomypathy.
