How does a capacitor act as a pacemaker?

A capacitor can act as a pacemaker by storing and releasing electrical energy in a controlled manner, mimicking the rhythmic electrical impulses generated by the heart's natural pacemaker cells. When charged, the capacitor discharges its stored energy at a specific rate, creating a pulse that can stimulate heart muscle contraction. This principle is utilized in electronic devices designed to regulate heart rhythms, helping to maintain a consistent heartbeat when the body's natural pacing is insufficient.
