The electrocardiogram (ECG) presents substantial changes associated with aging. In fact, the likelihood of having a "normal" ECG decreases with age. The most common findings are left ventricular hypertrophy pattern, leftward axis deviation and QRS widening. Interatrial block (IAB) is frequently present, mainly partial IAB. Atrial fibrillation prevalence raises from 6-7% in those aged 65-74years to 13-17% in those >75years.
心电图（ECG）显示出与衰老相关的显著变化。事实上，拥有“正常”心电图的可能性会随着年龄增长而降低。最常见的表现是左心室肥厚模式、电轴左偏和QRS波增宽。房内阻滞（IAB）经常出现，主要是不完全性IAB。房颤患病率从65 - 74岁人群中的6 - 7%升至75岁以上人群中的13 - 17%。
