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 ...
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 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 ...
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 ...
Patients requiring a pacemaker often have atrial fibrillation (AF), which increases the risk of thromboembolism and, consequently, the risk of morbidity and mortality. To maintain sinus rhythms, ...
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 ...
For years and years, physicians—including me—have told patients with atrial and ventricular arrhythmia to forgo the pleasures of chocolate and coffee. The joyous poster was born from the database of ...

Assessing heart-pumping glitch may reduce stroke risk in adults with heart muscle disease
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, ...
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, ...
