Overview

No therapy is required for premature atrial contraction in asymptomatic individuals. If necessary, medical therapy should begin with a beta blocker.

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.
