Myogenic heart contraction means the heart's beat is initiated by specialized cells (sinoatrial node) within the heart muscle, not by the brain.
A myogenic heart contraction means the signal for the heartbeat originates within the heart muscle itself, specifically from a cluster of cells called the sinoatrial node, rather than from external nervous system signals.
