Postablation follow-up
After the procedure, the patients underwent continuous electrocardiogram
(ECG) monitoring for approximately 3 days (until discharge). The
patients were followed-up at 1 and 3 months after discharge and
underwent a 12 lead ECG recording. We encouraged the patients to check
their pulse rate and rhythm every day and to visit our hospital if they
experienced any irregular pulses or chest discomfort. ERATs after the
ablation were defined as any recurrence of atrial tachyarrhythmias of
>30 seconds during the first 90 days of follow up. No
antiarrhythmic drugs were administered until ERAF occurred.
