|Time, Months||LVEF, %||Intervention|
|0||30||Diuretics, ACE inhibitors, TEE, cardioversion|
|14||—||Recurrent AF per patient; did not see a doctor|
|18||25||Cardioverted; started taking sotalol but discontinued due to increased QTc interval; amiodarone started|
|35||20||Admitted with heart failure; recurrent AF with rapid rates; underwent AF ablation; amiodarone continued|
|43||40||LA flutter with ventricular rate of 110 beats/min; underwent perimitral LA flutter ablation|
|63||53||Sinus rhythm; taking amiodarone (200 mg daily), beta-blockers, ACE inhibitor, warfarin|
ACE = angiotensin-converting enzyme; AF = atrial fibrillation; AIC = arrhythmia-induced cardiomyopathy; LA = left atrial; LVEF = left ventricular ejection fraction; TEE = transesophageal echocardiography.
