Background Previous epidemiological studies demonstrated that premature atrial contractions (PACs) and premature ventricular ...

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 ...

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 ...

Atrial fibrillation with rapid ventricular response is a fancy name for an irregular heartbeat. When your heart's electrical signals aren't working right, it can lead to a heartbeat that's too fast.

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 ...

Atrial fibrillation (AFib) with rapid ventricular response is a heart rhythm disturbance that puts you at higher risk for stroke and other serious complications. There are treatment options. Share on ...
