Postoperative Follow-ups
The patients were taken to the cardiovascular surgery intensive care unit after the surgeries and were followed-up there. During the intensive care process, the patients were followed-up with standard procedures as arterial pressure, blood gas, and D-II derivation continuous ECG. The electrolyte levels were closely monitored and corrected in the postoperative period. The 12-derivation ECG monitoring was performed continuously for patients who had arrhythmia or who had arrhythmia sensitivity, and arrhythmias were analyzed with 12-derivation ECG taken during arrhythmia. ECG telemetry was used in the follow-ups in the wards. The patients with AF episode for more than 5 minutes were accepted as PoAF (8).
