When a person's heart rate is less than 60 bpm, how does the heart try to pick up the rate?

Question

Quizplus · Accepted Answer

When the heart rate drops below 60 bpm, the heart may generate ventricular escape beats in order to pick up the rate. These are impulses that arise from a focus in the ventricles when the normal pacemaker of the heart (the sinoatrial node) is not functioning properly or is not generating impulses fast enough. This can help to maintain a minimum heart rate and prevent the heart from stopping altogether.
