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 ...

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 ...

Coffee consumption had a complex relationship with arrhythmias, a randomized trial with real-time electrocardiography patch monitoring showed. Premature atrial contractions weren't caused by coffee ...

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 ...

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 ...

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, ...

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 ...

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 ...

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 ...
