Atrial fibrillation can make your heart beat with an unsteady rhythm. If you have AFib and your heart is beating too slowly, you might need a pacemaker, along with other treatments, to keep it at ...
Pacemakers are battery-powered implantable devices that function to electrically stimulate the heart to contract and thus to pump blood throughout the body. Pacemakers consist of a pager-sized housing device which contains a battery and the electronic circuitry that runs the pacemaker, and one or two long thin wires that travel through a vein in the chest to the heart.
There are a number of different roles for pacemaker therapy in the management of Atrial Fibrillation (AF). The most com-mon indication for pacing in AF is to prevent bradycardia in patients with rapid ventricular rates and sinus node dysfunc-tion.
(See "Catheter ablation to prevent recurrent atrial fibrillation: Clinical considerations" and "Surgical ablation to prevent recurrent atrial fibrillation".) PATIENTS WITHOUT AN INDICATION FOR A PACEMAKER. In patients with a history of atrial fibrillation (AF), pacing from one or both atria has been suggested as a means to reduce AF recurrences.
Dual-site atrial pacing for atrial fibrillation in patients without bradycardia. Am J Cardiol 2001; 88:371–5. A multicentre, randomised, controlled study that shows the efficacy of dual site pacing in preventing both symptomatic and asymptomatic AF over sotalol in patients without bradycardia.
Pacemakers aren't a cure for atrial fibrillation, but they can play an important role in afib treatment. Find out how pacemakers stabilize heart rate and allow patients to take necessary medication.
However, a slow regular escape rhythm in atrial fibrillation suggests the presence of high-grade AV block, as do long pauses. When symptoms caused by bradycardia are present, pacemaker implantation is warranted (class I). When pauses in atrial fibrillation exceed 5 seconds, pacemaker implantation is a class IIa indication.
People with atrial fibrillation may need a pacemaker for a variety of reasons. These reasons include: You have atrial fibrillation that comes and goes. And you have a fast heart rate when you are in atrial fibrillation and a slow heart rate when you are not in atrial fibrillation. This is called tachy-brady syndrome.
