Observation: Most of PACs are benign and require little treatment. If no chest pain or no symptoms, PACs can change into or aggravate A Fib or SVT or A Flutter. PACs can be caused by stress or caffeine or tobacco or alcohol or HTN or underlying valve/heart disorder. May need to be evaluated by cardiologist of PACs continue. May need beta blocker or calcium channel blocker.

Background noise: Stimulants like caffeine, Nodoz, alcohol, energy drinks can precipitate PACs. However these need not be ingested to have PACs. Many patients have a burden of PACs that I describe as the "background noise of living". Bothersome is the understanding that these and PVCs are frequently the trigger for the faster rhythms that led to your ablation.With RFA your circuit is gone but these triggers remain.
