cardiac potentials

Cardiac potentials are electrical signals generated by heart cells to coordinate heartbeat. When heart cells receive a signal, their electrical charge changes, causing them to contract and pump blood. This electrical activity creates tiny voltage differences, which can be measured with an ECG. These potentials help ensure the heart beats in a rhythmic, synchronized way, efficient for pumping blood throughout the body. Essentially, cardiac potentials are the electrical language that controls the heart’s rhythm and strength of contraction.
