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 ...

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. When this occurs prior to ...

Atrial premature complexes (APCs) are early heartbeats originating in the atria, often causing palpitations or a feeling of skipped beats, and are usually harmless unless frequent or accompanied by ...

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 ...

An ectopic rhythm is an irregular heart rhythm due to a premature heartbeat. Ectopic rhythm is also known as premature atrial contraction, premature ventricular contraction, and extrasystole. When ...

(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 ...

DEAR DR. ROACH: What’s the difference between atrial fibrillation and premature ventricular contractions, aka PVCs (extra heartbeats)? -- M. ANSWER: Both AFib and PVCs are rhythm disturbances of the ...

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 ...
