Selective vagal stimulation for rate control in atrial fibrillation.
Several recent randomized clinical trials comparing strategies based on control of ventricular rate versus those based on maintenance of sinus rhythm in elderly or high risk patients with atrial fibrillation have recently been reported.1,2 Preliminary data from these trials suggest that the 2 strategies can produce roughly equivalent clinical outcomes. For individual patients, either approach m...
متن کاملOptimal ventricular rate slowing during atrial fibrillation by feedback AV nodal-selective vagal stimulation.
Although the beneficial effects of ventricular rate (VR) slowing during atrial fibrillation (AF) are axiomatic, the precise relationship between VR and hemodynamics has not been determined. We hypothesized that selective atrioventricular node (AVN) vagal stimulation (AVN-VS) by varying the nerve stimulation intensity could achieve precise graded slowing and permit evaluation of an optimal VR du...
متن کاملChronic atrioventricular nodal vagal stimulation: first evidence for long-term ventricular rate control in canine atrial fibrillation model.
BACKGROUND We have previously demonstrated that selective atrioventricular nodal (AVN) vagal stimulation (AVN-VS) can be used to control ventricular rate during atrial fibrillation (AF) in acute experiments. However, it is not known whether this approach could provide a long-term treatment in conscious animals. Thus, this study reports the first observations on the long-term efficacy and safety...
متن کاملInappropriate use of atrioventricular nodal vagal stimulation in atrial fibrillation.
Stimulation in Atrial Fibrillation To the Editor: Zhuang et al1 showed well that slowing the ventricular rate by atrioventricular nodal vagal stimulation (AVN-VS) improved hemodynamics during atrial fibrillation (AF). This gave better hemodynamic responses than slowing the ventricular rate by atrioventricular nodal ablation with right ventricular pacing, which caused adverse effects that the au...
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...
