Effect of atrial fibrillation and an irregular ventricular response on sympathetic nerve activity in human subjects.
BACKGROUND Although the hemodynamic changes associated with atrial fibrillation (AF) have been extensively studied, the neural changes remain unclear. We hypothesized that AF is associated with an increase in sympathetic nerve activity (SNA) and that the irregular ventricular response contributes to this state of sympathoexcitation. METHODS AND RESULTS In 8 patients referred for an electrophy...
متن کاملRenal sympathetic denervation provides ventricular rate control but does not prevent atrial electrical remodeling during atrial fibrillation.
Renal denervation (RDN) reduces renal efferent and afferent sympathetic activity thereby lowering blood pressure in resistant hypertension. The effect of modulation of the autonomic nervous system by RDN on atrial electrophysiology and ventricular rate control during atrial fibrillation (AF) is unknown. Here we report a reduction of ventricular heart rate in a patient with permanent AF undergoi...
متن کاملDronedarone for the control of ventricular rate in permanent atrial fibrillation: the Efficacy and safety of dRonedArone for the cOntrol of ventricular rate during atrial fibrillation (ERATO) study.
BACKGROUND Dronedarone is a new multichannel blocker for atrial fibrillation (AF) previously demonstrated to have both rhythm and rate control properties in paroxysmal and persistent AF. The Efficacy and safety of dRonedArone for The cOntrol of ventricular rate during atrial fibrillation (ERATO) trial assessed the efficacy of dronedarone in the control of ventricular rate in patients with perma...
متن کاملCardiac sympathetic nerve activity and ventricular fibrillation during acute myocardial infarction in a conscious sheep model.
The association between cardiac sympathetic nerve activity (CSNA) and ventricular fibrillation (VF) during acute myocardial infarction (MI) has not been assessed in conscious animal models. During the first 60 min post-MI, mean blood pressure (MBP), heart rate (HR), and CSNA were recorded continuously in 20 conscious sheep. Resistant sheep (group A, n = 10) were compared with susceptible sheep ...
متن کاملRate control in atrial fibrillation.
Untreated atrial fibrillation is usually associated with a rapid, irregular ventricular response and is often accompanied by symptoms including palpitations, fatigue, dyspnea, and dizziness. It is widely accepted that slowing the ventricular response, both at rest and during activity, with the use of drugs that prolong the refractory period of the atrioventricular (AV) node (so-called rate-cont...
