Persistent atrial fibrillation vs paroxysmal atrial fibrillation: differences in management

Expert Review of Cardiovascular Therapy, 2017
Atrial fibrillation (AF) is the most common human arrhythmia. AF is a progressive disease, initially being nonsustained and induced by trigger activity, and progressing towards persistent AF through alteration of the atrial myocardial substrate.

Paroxysmal atrial fibrillation in racehorses

Equine Veterinary Journal, 1986
Summary The paper describes five cases of atrial fibrillation detected after racing. In four of them, the arrhythmia disappeared spontaneously within 24 h and they were regarded as paroxysmal in type. In the fifth case, which won its race, the arrhythmia persisted for at least 45 h after racing. It was therefore regarded as an example

Propafenone for paroxysmal atrial fibrillation

The American Journal of Cardiology, 1988
Abstract Propafenone is a class 1C antiarrhythmic agent potentially effective in paroxysmal atrial fibrillation (AF). Propafenone's effects upon automaticity and conduction in the atrium should decrease the frequency of AF. In the event of a recurrence of AF, its effects on atrioventricular nodal conduction would tend to slow the ventricular response.

[PAROXYSMAL ATRIAL FIBRILLATION].

Bollettino della Societa italiana di cardiologia, 1996
Paroxysmal atrial fibrillation is an extremely common form of atrial fibrillation seen by most physicians. Despite making up more than 40% of the cases of atrial fibrillation, its management continues to be neglected in the medical literature. Many of the recent large-scale prospective trials have excluded these patients.

Management of paroxysmal atrial fibrillation

QJM, 1993
Paroxysmal atrial fibrillation is a common, poorly understood and difficult-to-treat arrhythmia. Although it tends to be treated in a similar fashion to chronic atrial fibrillation, its pathophysiology is different, and drugs commonly used for chronic atrial fibrillation may have only limited value in treating paroxysmal atrial fibrillation.

Paroxysmal Atrial Fibrillation in the Dog

Journal of the American Veterinary Medical Association, 1971
SUMMARY Paroxysmal atrial fibrillation occurred in 5 dogs and reverted to sinus rhythm without specific treatment for the arrhythmia. As is true for established atrial fibrillation, paroxysmal atrial fibrillation indicates serious cardiac disease and the prognosis is grave.

PAROXYSMAL ATRIAL FIBRILLATION IN A RACEHORSE

Australian Veterinary Journal, 1977
SUMMARY A 4‐year‐old thoroughbred stallion with a history of loss of racing form was studied over a period of approximately 7 months. At the initial examination he showed positive T waves in 1 chest lead and wandering of the pacemaker. This was followed by an episode of paroxysmal atrial fibrillation which disappeared spontaneously and was replaced by ...

Canine model of paroxysmal atrial fibrillation and paroxysmal atrial tachycardia

American Journal of Physiology-Heart and Circulatory Physiology, 2005
Both autonomic nerve activity and electrical remodeling are important in atrial arrhythmogenesis. Therefore, dogs with sympathetic hyperinnervation, myocardial infarction (MI), and complete atrioventricular block (CAVB) may have a high incidence of atrial arrhythmias.

Circadian Variation of Paroxysmal Atrial Fibrillation

Circulation, 1997
Background Circadian variation in the incidence of acute cardiovascular events is well known but has not been extensively investigated in paroxysmal atrial fibrillation, although the significance of this arrhythmia is growing in our society with the increasing number of aged people. Methods and

Catheter Ablation for Paroxysmal Atrial Fibrillation

New England Journal of Medicine, 2012
Atrial fibrillation is the most common cardiac arrhythmia, with a lifetime risk exceeding 20% by 80 years of age.1 Despite associations of atrial fibrillation with heart failure, stroke, and increased mortality, antiarrhythmic drug therapy with the goal of maintaining sinus rhythm has not improved outcomes in randomized trials.2,3 Recently, attention ...
