Premature atrial contraction medical therapy
Introduction
Overview
Overview
No therapy is required for premature atrial contraction in asymptomatic individuals. If necessary, medical therapy should begin with a beta blocker.
Medical Therapy
Medical Therapy
- Most patients with PACs are asymptomatic and hence require no treatment.
- Beta blockers can reduce the symptoms related to PACs and may reduce their frequency. However, the response to beta blockers is inconsistent and variable.
- Class IA, class IC, and class III antiarrhythmic agents are considered if premature atrial contractions precipitate or trigger other supraventricular arrhythmias including atrial fibrillation and atrial flutter.
