Table 5. Clinical Characteristics in Patients with a History of Paroxysmal Atrial Fibrillation.

CHF = congestive heart failure; BNP = brain natriuretic peptide; LAD = left atrial diameter; LVEF = left ventricular ejection fraction; BP = blood pressure; M = month; HR = heart rate; AF = atrial fibrillation; CAF = chronic AF.
