The high prevalence of interatrial block (IAB) is widely neglected due to its frequent underdiaguosis. Its prevalence depends mainly on age and also on the presence of associ- ated heart disease.

Its prevalence depends mainly on age and also on the presence of associ- ated heart disease. In patients without structural heart dis- ease, it is mainly an elderly condition. This is particularly true for advanced IAB, rarely found in global population before 65 years but with prevalence of 8% in the 70's and 25% in centenarians,tll When studying prevalence data of this condition, three factors should be taken into account in order to interpret differences that are frequently related with the methodology used (Table 1, Figure 1).展开更多

Due to population aging, AF is a growing epidemic and its importance will continue to increase in the next decades. Although the prevalence of AF is high in advanced age, the number of subjects with predisposing factors for AF is even higher. Most of these factors increase the risk of atrial fibro- sis, an important component of atrial arrhythmia mecha- nisms. In fact, the new techniques to detect atrial fibrosis are showing the strong association between atrial fibrosis and AF risk. Regarding predisposing factors for AF, interatrial block (LAB) seems to be a key factor.展开更多
