Background: Until now, no clinically useful indicators have existed that predict the transition from paroxysmal to persistent atrial fibrillation (AF).
Hypothesis: The current prospective study was conducted for identifying predictors of progression to persistent AF over the long term.
Methods: We studied 102 consecutive patients (mean age: 55 +/- 10 years: 75 men and 27 women) diagnosed with paroxysmal AF.
