BACKGROUND Atrial fibrillation (AF) is a commonly encountered arrhythmia in clinical practice, and it occurs frequently after cardiac surgery. The P-wave signal-averaged (SA) ECG noninvasively detects atrial conduction delay. Prior studies have described greater P-wave prolongation in patients with a history of AF, but prospective studies have not been performed. METHODS AND RESULTS Consecutive patients undergoing cardiac surgery were enrolled. The P-wave SAECG was recorded before surgery… CONTINUE READING
