BACKGROUND: Premature atrial contractions (PACs) are independently associated with atrial fibrillation, stroke, and heart failure, yet no pharmacological therapy is approved for PAC suppression.

In the last few weeks, the Skeptical Cardiologist has had a run on with patients with premature atrial contractions (PACs). I've discussed in detail premature ventricular contractions (PVCs) here and ...

A premature atrial contraction (PAC) occurs when a focus in the atrium (not the SA node), generates an action potential before the next scheduled SA node action potential. There are four main ...

(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 ...

October 10, 2012 (Basel, Switzerland) — Premature atrial contractions (PACs) occur in the majority of people aged over 50, and their frequency is independently associated with a number of risk factors ...

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 ...

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 ...

A commonly used heart monitor may be a simple tool for predicting the risk of atrial fibrillation, the most frequently diagnosed type of irregular heart rhythm, according to researchers. A commonly ...

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 ...
