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 ...


(See "Atrial fibrillation: Catheter ablation" 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.


in the management of Atrial Fibrillation (AF). The most fre-quent indication for pacing in AF is to prevent bradycardia in patients with rapid ventricular response and sinus node dysfunction. For elderly patients or patients with signifi-cant medical comorbidities who have highly symptomatic, drug-refractory AF, pacemaker implantation and atrioven-


In patients with a left ventricular ejection fraction between 36% to 50% and AV block, who have an indication for permanent pacing and are expected to require ventricular pacing >40% of the time, techniques which provide more physiologic ventricular activation (cardiac resynchronization therapy or His bundle pacing) are reasonable in preference ...


Indications for pacemaker. Bradyarrhythmia is the main indication for implantation of a pacemaker. When considering a permanent pacemaker for bradyarrhythmia, it is important to distinguish persistent, reversible and intermittent bradycardia.The pathophysiology and prognosis differ for these entities.


Introduction. Atrial fibrillation (AF) is the most common arrhythmia, whose incidence increases with age, and the prevalence in the general population is 1.5-2% [].AF is associated with twofold increase in mortality, threefold increase in the incidence of congestive heart failure and fivefold increase in the incidence of stroke [1, 2].Oral anticoagulation (OAC) therapy significantly decreases ...


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.

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.


I. Introduction. The publication of major studies dealing with the natural history of bradyarrhythmias and tachyarrhythmias and major advances in the technology of pacemakers and implantable cardioverter-defibrillators (ICDs) has mandated this revision of the 1991 ACC/AHA Guidelines for Implantation of Pacemakers and Antiarrhythmia Devices.


In 1977, Moss et al. reported their ten-year experience with atrial pacing from the coronary vein in 50 patients with implanted pervenous pacemakers. 3 The indications for atrial pacing were symptomatic sinus bradycardia (72%), atrial bradycardia-tachycardia (brady-tachy) syndrome (20%) and recurrent tachyarrhythmias (8%). Follow-up averaged 31 ...
