(HealthDay News) – Premature atrial contraction (PAC) count improves atrial fibrillation (AF) risk model performance, according to a study published in the Dec. 3 issue of the Annals of Internal ...

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 ...

Most of us have had that unsettling sensation when our heart seems to flutter or "skip" a beat — but when heart palpitations start happening more frequently, you may wonder if it’s something to get ...

Data from large-scale epidemiologic studies to support an association between PM exposure and atrial arrhythmias are lacking. The findings of the aforementioned studies are limited in generalizability ...

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 ...
