Atrial fibrillation with slow ventricular response symptoms

In a relatively minor procedure, a small burn is made to the connection that connects the top and bottom chambers of the heart. A pacemaker is then inserted . This prevents Afib with RVR as although the top chambers continue to fire at a fast rate, the pacemaker now controls the bottom chamber, in a nice regular way.

Ventricular slowing is accomplished with medications affecting the AV node (Table 1). The most commonly used drug classes are beta blockers and calcium channel blockers. Most patients with persistent atrial fibrillation receive daily suppressive therapy.

Abstract. Atrial flutter (AF) is a troublesome arrhythmia for patients with an implanted pacemaker . Although it has recently become possible to eliminate AF by radiofrequency catheter ablation (RF-CA), the incidence of AF before and after pacemaker implantation has not been clarified.

There is no agreement on the definition of atrial fibrillation (AF) with a slow ventricular response: the condition may be characterized as an AF with slow resting heart rate or as an AF with normal resting heart rate but with prolonged ventricular pauses .
