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 ...

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 ...

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 ...

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, ...

At times it can be difficult to distinguish "SVT with aberrancy" from ventricular tachycardia. This QRS morphology has a typical left bundle branch block pattern, is irregular and does not meet the ...

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 ...

Pay attention to the compensatory pauses after the premature ventricular contraction (PVC) (denoted by ↑) in tracing “b” of Figure 1, then answer the question below.

The term resetting comes from engineering and is used when "a system (a clock for example) is restored back to zero." Resetting of a cardiac rhythm can be easily understood if one compares what is ...
