HEART RATE VARIABILITY AND HEART RATE DYNAMICS AFTER RADIOFREQUENCY CATHETER ABLATION
Abstract
Relevance. Radiofrequency catheter ablation (RFCA) is one of the effective rhythm-control strategies for atrial fibrillation (AF) and certain other supraventricular arrhythmias. The procedural effect is not limited to elimination of arrhythmogenic foci: ablation can influence cardiac autonomic innervation and reflex control mechanisms, leading to autonomic re-adaptation in the early post-procedural period. In clinical practice, this is often reflected by changes in resting heart rate (HR) and shifts in heart rate variability (HRV) parameters.
