报道老年前期心电图363例,其异常心电图检出率为33.3％,以窦缓、传导阻滞、期前收缩等多见,男女之间差异无显著性。心电图异常组高血压和临床心脏病的患病率高于心电图正常组;而高血脂和眼底动脉硬化两组差异无显著性。随着增龄,心血管病患病率有增加,异常心电图检出率亦呈平行性增加,提示老年前期的心电图改变是获得性的。
Reported 363 cases of pre-senile electrocardiogram, the abnormal electrocardiogram detection rate was 33.3%, sinus delay, conduction block, premature rupture and other common, no significant difference between men and women. The prevalence of hypertension and clinical heart disease in ECG abnormal group was higher than that in normal ECG group, while there was no significant difference between hyperlipidemia and fundus arteriosclerosis group. With age, the prevalence of cardiovascular disease has increased, abnormal ECG detection rate was also increased parallelism, suggesting that pre-elderly ECG changes are acquired.
