Background and objective Prior studies have suggested that patients with premature ventricular complexes (PVCs) may have an increased risk for atrial fibrillation (AF) and stroke. It is unclear ...

Atrial fibrillation (AFib) is a heart rhythm problem involving your heart’s upper chambers (atria). Heart failure and stroke are among the more serious possible complications of AFib. The complication ...

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 ...

In tracing "a" of Figure 1, there seems to be only one P wave in front of each QRS complex, suggesting sinus rhythm. However, during the compensatory pauses after the PVCs (↑) in tracing "b," there ...

Peter Spector, M.D.; Nicole Habel, M.D. iii Shorthand convention meaning "advances the timing of the subsequent atrial activation." iv Delivered during His refractoriness v The conclusions that we are ...

Palpitations due to premature beats, either ventricular contractions (PVCs) or atrial contractions (PACs), can be extremely vexing even when we know they are benign. For many individuals, these ...

Philadelphia, PA, Oct. 27, 2017 - 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 ...

Philadelphia, October 12, 2022 – Extended cardiac monitoring in patients and the use of implantable cardiovascular electronic devices can increase detection of atrial fibrillation (AF), but the ...
