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 ...

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 ...

Atrial dysfunction, widely considered a marker or consequence of other heart diseases, is a relevant clinical entity, which is why it is justified to define atrial failure or insufficiency as "a new ...

MANY common arrhythmias observed in both atria and ventricles are similar although the atrial types have a few important distinguishing features. Thus, so far as therapy is concerned, the atrial ...

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 ...

Recent studies have determined that blacks have a lower risk of atrial fibrillation (AF) compared with whites despite having a higher prevalence of risk factors such as hypertension and heart failure.

A hidden atrial dysfunction may raise stroke risk in people with transthyretin amyloid cardiomyopathy (ATTR-CM); however, a noninvasive assessment tool may help identify those at increased risk, ...

I've been using AliveCor's Kardia personal ECG devices to help manage my patients with atrial fibrillation (AF) for 7 years now. Early on, I pointed out (see here) that Kardia was easily confused by ...

What is atrial fibrillation, and why has Apple decided that it’s worth screening for it? The first question is much easier to answer, so let’s get that out of the way. Your heart has four chambers, ...
