PO-677-04 INITIAL HEART RATE SCORE PREDICTS OCCURRENCE OF NEW ATRIAL FIBRILLATION IN PACEMAKER PATIENTS

Heart Rate Score (HRSc), the percent of beats in the tallest atrial paced & sensed 10 bpm histogram bin, predicts survival in ICD & CRT-D pts without AF. No studies have reported the correlation between initial HRSc & subsequent development of AF in pacemaker pts. We focused on the incidence of newly developed AF after PM implantation.
