Efficacy of ventricular rate stabilization by right ventricular pacing during atrial fibrillation

Abstract

To assess the effect of right ventricular pacing on rate regularity during exercise and daily life activities, 16 patients with sinoatrial disease and chronic atrial fibrillation (AF) were studied. Incremental ventricular pacing was commenced at 40 beats/min until > 95% of ventricular pacing were achieved during supine, sitting, and standing. Thirteen patients also underwent randomized paired submaximal exercise tests in either a fixed rate mode. (VVI) or a ventricular rate stabilization (VRS) mode in which the pacing rate was set manually at 10 beats/min above the average AF rate during the last minute of each exercise stage. The pacing interval for rate regularization was shortest during standing (692 +/- 26 ms) compared with either supine or sitting (757 +/- 30 and 705 +/- 26 ms, respectively, P < 0.05). During exercise VRS pacing significantly increased the maximum rate (119 +/- 5.2 vs 106 +/- 4.2 ms, P < 0.05), percent of ventricular pacing (85% +/- 5% vs 23% +/- 7%, P < 0.05), rate regularity index (5.8% +/- 1.6% vs 13.4% +/- 1.9%, P < 0.05), and maximum level of oxygen consumption (12.4 +/- 0.5 vs 11.3 +/- 0.5 mL/kg, P < 0.05) compared with VVI pacing. There was no change in oxygen pulse or difference in symptom scores 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.

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.
