Inappropriate 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 کاملIncrease of ventricular interval during atrial fibrillation by atrioventricular node vagal stimulation: chronic clinical atrioventricular-nodal stimulation download study.
BACKGROUND Patients with a high ventricular rate during atrial fibrillation (AF) are at increased risk of receiving inappropriate implantable cardioverter defibrillator shocks. The objective was to demonstrate the feasibility of high frequency atrioventricular-nodal stimulation (AVNS) to reduce the ventricular rate during AF to prevent inappropriate implantable cardioverter defibrillator shocks...
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 کاملEffect of continuous enhanced vagal tone on atrioventricular nodal and sinoatrial nodal function in humans.
A constant intravenous infusion of phenylephrine (0.74 +/- 0.41 micrograms/kg/min) was given to 10 patients to cause a continuous augmentation in reflex vagal tone. After the infusion, the diastolic blood pressure increased from 76 +/- 7 to 89 +/- 11 mm Hg (p less than 0.01). The sinus cycle length and atrial-His (AH) interval were measured, and incremental atrial pacing was performed before an...
متن کاملQuantification of human atrioventricular nodal concealed conduction utilizing S1S2S3 stimulation.
We studied antegrade concealed conduction of atrial extrastimuli (A2) that blocked in the atrioventricular (AV) node in eight subjects, using a third extrastimulus (A3), coupled at decreasing coupling intervals to A2. Three A1-A2 intervals were tested in each subject: late (just shorter than AV nodal effective refractory period), intermediate, and early (just longer than atrial functional refra...
