RECURRENCES, HEART
Figure Heart rate on index ECG, minimum, median, maximum and delta heart rate during recurrences by randomization group (early vs. delayed cardioversion). (A–E) show histograms for heart rate characteristics for patients in the delayed (pink) and early (blue) cardioversion group. Purple bars indicate overlap between the two. bpm, beats per minute; ECG, electrocardiogram.Heart rate on index electrocardiogram and during AF recurrences and medication use and adaptation during the index visit by randomized group.
Abbreviations: AAD, antiarrhythmic drugs; BB, beta blocker; bpm, beats per minute; ECG, electrocardiogram; NCCB, non dihydropyridine calcium channel blocker.Rate control medication = BB, digoxin, NCCB (verapamil) or class III AADs (amiodarone or sotalol).Only calculated for BB and sotalol (1 patient using amiodarone was excluded). Median dosages of digoxin and NCCB were not calculated due to small numbers (since BB adaptation was defined as first choice in the protocol).Normalized to metoprolol equivalent doses. At index 27 patients used metoprolol, 6 used bisoprolol, 2 used atenolol and 2 used propranolol. If a beta blocker was newly started this was always metoprolol, except in one patient (bisoprolol).
