    Abstract:
    We investigated the influence of Holter duration on the detection of recurrences after ablation for atrial fibrillation (AF). Two-hundred-and-fifteen patients underwent a 7-day Holter ECG at 6 months after catheter ablation. We analyzed the number of patients who had a recurrence within the first 24, 48, 72 h etc. up to the total of 7 days. During the complete 7-day recording, 30% had a recurrence. All Holter durations ≤5 days would have detected significantly less patients with recurrence than the complete 7-day recording. A 24-hour Holter would have detected 59%, a 48-hour Holter 67% and a 72-hour Holter 80% of patients with recurrences, whereas a 4-day recording would have detected 91% of the recurrences that were detected with the complete 7-day recording. In conclusion, a Holter duration of less than 4 days misses a great portion of recurrences, whereas a 4-day recording might offer a reasonable compromise.
