Incidence of Long-TeRm Atrial Fibrillation After Acute Illness

The investigators seek to conduct a prospective study to assess the recurrence of AF in patients with acute AF using a long-term ECG monitoring strategy with an insertable cardiac monitor (ICM), which is clinically indicated in this scenario as part of the standard of care. The investigators hypothesize that patients diagnosed with acute AF in the setting of cardiac surgery will have higher rates of AF recurrence than acute AF diagnosed in the setting of non-cardiac surgery or medical illness.
