What is post-systolic potentiation?
Because the PVC (premature ventricular contraction) comes early, there is more time before the next beat, meaning that there is more time for the heart to fill. Because of more filling, there is more initial tension on the cardiac muscle, eliciting a stronger contraction from the heart. Also, the PVC is a weak contraction, so the heart does not fully empty, and there is more residual blood in the heart even before it starts filling again.
