Question

how do the electric signals maintain the heart's rhythm?

Answer 1

Electric signal in the heart is generated by the sinoarterio node, which is a group of cells capable of generating electrical impulses. Together with the arteriventricular, the sinoarterio node maintains impulses that causes the muscles of the heart to contract and relax rhythmically The impulses are coordinated ensuring that in a healthy person a rhythm is always maintained.
