Szívizomkontrakció refers to the process by which the heart muscle contracts, leading to the pumping of blood throughout the body. This vital physiological function is a complex, coordinated event involving electrical and mechanical components.
The cardiac cycle begins with electrical impulses originating in the sinoatrial (SA) node, often called the
Following the delay at the AV node, the impulse is rapidly conducted through the ventricles via the
The relaxation phase, known as diastole, follows contraction (systole). During diastole, the heart muscle relaxes, and
