ACC/AHA Guidelines- Recommendations for Permanent Pacing in Sinus node Dysfunction

“

Class I Permanent pacemaker implantation is indicated for SND with documented symptomatic bradycardia, including frequent sinus pauses that produce symptoms. (Level of Evidence: C) Permanent pacemaker implantation is indicated for symptomatic chronotropic incompetence. (Level of Evidence:C) Permanent pacemaker implantation is indicated for symptomatic sinus bradycardia that results from required drug therapy for medical conditions.(Level of Evidence: C)

”

Bradyarrhythmias are well controlled with pacemakers, while tachyarrhythmias respond well to medical therapy. However, because both bradyarrhythmias and tachyarrhythmias may be present, drugs to control tachyarrhythmia may exacerbate bradyarrhythmia. Therefore, a pacemaker is implanted before drug therapy is begun for the tachyarrhythmia.
