hey everyone it's Nera and in this video I'm going to be going over premature ventricular contractions so let's get started pbcs are early contractions that originate in the ventricles so we're ...
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 ...
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 ...
