SAN FRANCISCO, CA — Knowing the number of hourly premature atrial contractions (PACs) a patient has is as good as the Framingham atrial fibrillation (AF) risk algorithm in predicting five- to 15-year ...

If a premature atrial contraction occurs when the AV node has not yer recovered from the refractory period, the PAC will fail to conduct to the ventricles and there will not be a QRS complex ...
