paroxysmal atrial fibrillation. Canad J Cardiol 2014; 30: S287-S288, doi: 10.1016/j.cjca.2014.07.512.
Point-by-point radiofrequency ablation versus the cryoballoon or a novel combined approach: a randomized trial comparing 3 methods of pulmonary vein isolation for
paroxysmal atrial fibrillation (the Cryo Versus RF Trial).
It also shows an excellent one year arrhythmia-free survival even when accounting for the continuous monitoring strategy, the inclusion of very dilated left atria and the exclusion of patients with
paroxysmal atrial fibrillation.
Paroxysmal atrial fibrillation may also cause moderate natriuretic peptide increases reflecting atrial dysfunction, even in the absence of ventricular dysfunction (4).

An enlarged left atrial appendage could be explained by
paroxysmal atrial fibrillation, or be an independent risk factor of stroke.
Epidemiology data have provided important information about the natural history of
paroxysmal atrial fibrillation (AF), and its relationship to chronic AF and its adverse effects on long-term mortality.
P wave dispersion can be used to predict idiopathic
paroxysmal atrial fibrillation. In normal healthy children, the normal P dispersion has been described as 27.0+-5.4ms.2,3,10 In our study, P dispersion was measured as 30.8+-11.4 ms before the procedure, but changes in the atrial myocardium may become more overt with age because of the continuous pressure and potential volume overload.
However, a recent study that included patients with asymptomatic
paroxysmal atrial fibrillation (monitoring electrocardiogram: atrial fibrillation with ventricular rhythm [greater than or equal to] 190b/min for more than 30 seconds) and patients in sinus rhythm showed that
paroxysmal atrial fibrillation does not associate with the aggravation of clinical symptomatology or the ventricular remodelling in patients with cardiac resynchronisation therapy.
