Both atrial flutter and atrial fibrillation can be treated with an electric shock (direct current cardioversion), with medications, or with a catheter-based "ablation" procedure, where little burns are placed on the inside of the atria.

He was a coinvestigator in a Mayo Clinic study that showed the risk of recurrence of atrial fibrillation in the year following direct current cardioversion of the arrhythmia in patients with obstructive sleep apnea (OSA) was cut in half by continuous positive airway pressure (CPAP) therapy (Circulation 2003;107:2589-94).
This prospective, randomized, double-blind study was designed to compare the recovery characteristics of remifentanil and fentanyl in combination with propofol for direct current cardioversion. Patients undergoing elective cardioversion received either intravenous fentanyl 1 [micro]g/kg (n = 33) or remifentanil 0.25 [micro]g/kg (n = 30) and propofol was titrated to a Ramsay sedation score of 5 by slow intravenous injection.
