Interatrial block (IAB; P-wave duration>or=110 ms) is highly prevalent and is strongly associated with atrial tachyarrhythmias and left atrial dysfunction. Very few studies have examined IAB in young healthy subjects. The aim of the present study was to demonstrate the prevalence of IAB and its possible relation with clinical variables in 1,353 young healthy men. It was found that 9.1% of healthy men aged<35 years and 5.4% of those aged<20 years had P-wave durations>or=110 ms. The frequent presence of IAB in leads II, V3, and V5 was also observed. Age and heart rate were independent significant determinants of IAB. In conclusion, IAB is a frequent phenomenon, even at young ages. Thus, the early recognition of IAB might be important, possibly contributing to the prevention of future cardiovascular complications.
房间阻滞（IAB；P波时限≥110毫秒）极为常见，且与房性快速心律失常及左心房功能障碍密切相关。很少有研究对年轻健康受试者中的房间阻滞进行过检查。本研究的目的是证实1353名年轻健康男性中房间阻滞的患病率及其与临床变量的可能关系。结果发现，年龄<35岁的健康男性中有9.1%以及年龄<20岁的健康男性中有5.4%的P波时限≥110毫秒。在Ⅱ、V3和V5导联中也观察到房间阻滞频繁出现。年龄和心率是房间阻滞的独立显著决定因素。总之，房间阻滞是一种常见现象，即使在年轻时也是如此。因此，早期识别房间阻滞可能很重要，这可能有助于预防未来的心血管并发症。
