The stroke volume ejected on the next heartbeat after premature ventricular contraction (PVC) is usually larger than normal. Explain why this is the case.

The stroke volume ejected on the next heartbeat after premature ventricular contraction (PVC) is usually larger than normal. Explain why this is the case. (HINT: It should be noted that at a given heart rate, the interval between a PVC and the next normal beat is longer than the interval between two normal beats.)
