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 ...

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 at UC San ...

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 ...

Adding retinoic acid from day 4 to day 7 induces stem-cell-derived cardiomyocytes to form tissue resembling atrial heart muscle. (Courtesy: Stem Cell Reports 10.1016 ...

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

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 ...
