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 ...

BACKGROUND: Premature atrial contractions (PACs) are independently associated with atrial fibrillation, stroke, and heart ...

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 ...

Do you ever feel like your heart misses a beat? There’s a good chance that what you noticed was a heartbeat that happened sooner than it usually does. When that happens, and then follows up with a ...

let's go over premature atrial contractions so these are sometimes referred to as pac's and they're early contractions that originate from a focal point in the Atria rather than the SA node and this ...

THE diagnosis of ventricular tachycardia without retrograde activation of the atrium is dependent upon the location of regular atrial activity that is independent of the faster ventricular rate. The ...

Li and her colleagues worked with both a mouse model of atrial fibrillation and with human heart tissue from patients with the condition. In the mouse model, the researchers genetically engineered ...

Atrial fibrillation is the most common arrhythmia - problems with the speed or rhythm of the heartbeat. Arrhythmias are caused by a disorder in the heart's electrical system. The walls of the atria ...
