目的:探讨肥厚型心肌病患者的心电图变化及其临床意义。方法:对88例肥厚型心肌病患者(I型前间壁肥厚28例,II型前间隔、后间隔均肥厚36例,III型左心室前壁或/和后壁、侧壁肥厚14例,IV型心尖部肥厚10例)行常规12导联心电图检查。结果:心电图异常(ST-T改变,异常Q波,心室肥厚等)发生率为93.2%。IV型ST-T改变多见于前侧壁、高侧壁,具有特殊性。其它3型患者ST-T改变、异常Q波的发生率及部位差异均无显著性意义。结论:肥厚型心肌病患者大多存在不同程度的心电图异常,但除心尖肥厚型心肌病外,其它各型心电图改变没有特异性。
Objective: To investigate the changes of ECG and its clinical significance in patients with hypertrophic cardiomyopathy. Methods: A total of 88 patients with hypertrophic cardiomyopathy (type I anteroseptal hypertrophy in 28 cases, type II anterior septum, posterior septum were hypertrophy in 36 cases, type III left ventricular anterior wall or / and posterior wall, lateral wall hypertrophy in 14 cases, IV Type apex hypertrophy in 10 cases) routine 12-lead ECG. Results: The incidence of abnormal electrocardiogram (ST-T changes, abnormal Q waves, ventricular hypertrophy, etc.) was 93.2%. IV type ST-T changes more common in the anterior wall, high side wall, with particularity. There was no significant difference in the incidence of ST-T changes, abnormal Q-waves and site differences in other type 3 patients. Conclusion: Most patients with hypertrophic cardiomyopathy have abnormal electrocardiogram (ECG) to some extent. However, there are no specific ECG changes except for apical hypertrophic cardiomyopathy.
