Abstract

Atrial fibrillation (FA) is the most common arrhythmia, and frequency of its occurrence increases with age. The aim of this study was to assess the influence of sinus rhythm (SR) restoration on heart rate (HR) and ventricular arrhythmia (AEV) and pauses (PA) occurrence in patients in over 70 years age. Study group consists with 104 patients with nonrheumatic FA of different etiology, which were divided to two groups: in younger and older age. In group I (younger patients) were 52 patients (25 women and 27 men), 38 to 69 (mean 51.2 +/- 14.2) years old. In group II (older patients) were 52 patients (23 women and 29 men), 70 to 86, (mean 71.3 +/- 5.5) years old. In all patients Holter monitoring before reversion of atrial fibrillation was performed. Consequently sinus rhythm (SR) was restored using pharmacological or electrical cardioversion. After SR stabilization next Holter monitoring was performed. The following electrocardiographic parameters was assessed: mean heart rate (HR mean), maximal heart rate (HR max), minimal heart rate (HR min), occurrence of AEV and PA over 2000 ms duration time. The PA over 2000 ms duration time occurred significantly more often during FA than after SR restoration. HR max was significantly higher...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.

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.

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.

Anti-Arrhythmic Drug Therapies

Anti-arrhythmic drugs are used to prevent abnormal heart rhythms. These medications are used in conditions including, ventricular tachycardia, ventricular fibrillation and atrial fibrillation. Discover the latest research on anti-arrhythmic drug therapies here.
