The importance of the longest R-R interval on 24-hour electrocardiography in mortality prediction in patients with atrial fibrillation
BACKGROUND: Heart rate control in atrial fibrillation (AF) is typically assessed by 24-hour electrocardiography (ECG). There are scarce data on the use of 24-hour ECG parameters to predict mortality in AF.AIMS: We aimed to identify 24-hour ECG parameters that predict mortality in AF.METHODS: We enrolled 280 ambulatory patients (mean [SD] age, 72.0 [8.7] years; 57.9% men) with permanent or persiste
