Development of atrial flutter after induction of general anesthesia and conversion to atrial fibrillation: A case report

ABSTRACT

The most frequent perioperative cardiovascular event is cardiac dysrhythmia, defined as an abnormality of cardiac rate, rhythm or conduction. Although the occurrence of arrhythmia during the perioperative period is not uncommon, a case of newly developed perioperative atrial flutter which spontaneously converts to atrial fibrillation is rare. We report a case of atrial flutter that developed immediately after induction of general anesthesia, in a 70-year-old male patient who previously had a normal sinus rhythm. Atrial flutter changed spontaneously to atrial fibrillation after discharge to the recovery room. Dysrhythmia was unresponsive to drug therapy, and the atrial fibrillation disappeared after electric cardioversion.
