Abstract

Pharmacological and direct-current cardioversion of atrial fibrillation are often performed interventions. Little is known about results and complications of cardioversion in daily practise. Demographic, procedural and outcome data from patients with cardioversion of atrial fibrillation were collected in a prospective, multicenter registry of 61 hospitals. Between July 1994 and December 1994 1152 patients with a mean age of 64 +/- 11 years were registered on an intention-to-treat basis. 62% were male. The most prevalent underlying disorders were coronary artery disease (34.7%), valvular heart disease (18.1%), and cardiomyopathy (6.9%). 16.4% of patients had lone atrial fibrillation. New onset atrial fibrillation was reported in 21%, paroxysmal in 32% and chronic in 47% of patients. The mean duration of atrial fibrillation was 7 +/- 26 weeks (range 1 day to 7 years, median 5 days). In 3.8% of patients no cardioversion attempt was made and follow-up was not possible in another 5.5%. 19.2% of patients cardioverted spontaneously. Direct current cardioversion was attempted in 39.7% and pharmacological cardioversion in 31.8% of patients. Cardioversion was successful (sinus rhythm at discharge) in 96.4% of spontaneous cardioversion, i...Continue Reading

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
