BACKGROUND
Interatrial block (IAB: P wave > or = 110 ms) is highly prevalent in people > or =65 years old living in a community.
METHODS
We investigated 720 consecutive people age > or =65 years old, from the general population, with the intention of evaluating the prevalence of IAB in their electrocardiogram. After excluding 42 people with atrial fibrillation and atrial flutter (5%) or having a permanent pacemaker (0,83%), we evaluated the electrocardiograms of the remaining 678 people with sinus rhythm.
RESULTS
We identified 400 (59%) persons with IAB with a similar distribution between men (58.5%) and women (59.4%). IAB was also identified in 347 from a total of 570 hypertensive people (60,9%) and only in 53 out of 108 (49.1%) nonhypertensive people (P = 0.015).
CONCLUSIONS
The surprisingly large prevalence of the IAB in the general older population emphasizes the importance of the early recognition of this abnormality from the surface 12-lead electrocardiogram.
背景
房间阻滞（IAB：P波≥110毫秒）在社区中65岁及以上人群中极为普遍。
方法
我们对720名年龄≥65岁的普通人群进行了调查，目的是评估其心电图中IAB的患病率。在排除42名患有房颤和房扑（5%）或植入永久起搏器（0.83%）的患者后，我们对其余678名窦性心律患者的心电图进行了评估。
结果
我们确定了400名（59%）患有IAB的患者，男性（58.5%）和女性（59.4%）的分布相似。在570名高血压患者中，有347名（60.9%）被发现患有IAB，而在108名非高血压患者中，只有53名（49.1%）被发现患有IAB（P = 0.015）。
结论
IAB在普通老年人群中惊人的高患病率强调了从体表12导联心电图早期识别这种异常的重要性。
