A premature ventricular contraction occurs when a focus in the ventricle generates an action potential before the next scheduled sinoatrial nodal action potential. Ventricular bigeminy occurs when ...
What Are Premature Ventricular Contractions (PVCs)? If your heart feels out of rhythm or “flutters,” especially when you're anxious or stressed, it could be caused by premature ventricular ...
Premature ventricular complexes (PVCs) are extra heartbeats originating from the heart’s lower chambers, potentially causing palpitations or fluttering sensations. While occasional PVCs are common, ...
In a normal heart rhythm, your heart beats in a steady, even way. The upper part of your heart (atria) squeezes and pushes blood to the lower part (ventricles), pumping blood and oxygen out to the ...
The regular arrhythmia occurring at the beginning of the electrocardiogram was identified as ventricular bigeminy. Single ventricular premature complexes (VPCs), as well as pairs and triplets of VPCs, ...
Note the premature ventricular contraction (PVC) that triggers the AVNRT in this ECG. If a premature atrial contraction (PAC) or premature ventricular contraction (PVC) occurs at the right time, the ...
The correct diagnosis is sinus rhythm with premature ventricular contractions and ventricular parasystole (Figure 2). Figure 2. Courtesy of Philip J. Podrid, MD. The rhythm is irregular. There are ...

What Causes Bigeminy and When Should You Worry?
Bigeminy is an irregular heart rhythm where every normal beat is followed by an abnormal one, often due to premature ventricular contractions (PVCs). It can feel like skipped or extra beats, but in ...
Losartan, enalapril and amlodipine reduced the number of premature ventricular contractions (PVCs) in patients with essential hypertension as well as blood pressure. The effect of losartan was the ...
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 healthy 33-year-old woman with no cardiac risk factors feels thumps or skipped beats in her chest a few times a day regardless of activity. An event recorder showed premature ventricular ...
