Interatrial block as electrocardiographic predictive sign for atrial fibrillation in Internal Medicine Departments hospitalized patients
Abstract
This study evaluated the correlation between interatrial block (IAB) and atrial fibrillation (AF) among patients admitted to our Internal Medicine Unit: 110 (group 1) were identified with electrocardiograms both in sinus rhythm and AF, and 123 (group 2) constantly in sinus rhythm. In both we analyzed: the presence of partial (P≥120 msec) or advanced (P>120 msec and biphasic in D2, D3, aVF) IAB, and the main electrocardiographic and clinical features. Age and gender between the two groups were similar. IAB was present in 89/110 (80.91%,) in group 1 and 26/123 (21.13%) in group 2 (P=0.1 mV (P0.1 mV.
