The heart rate is measured in beats/ minute and a “beat” is when the lower chambers are (two ventricles) contract. This process pushes the blood into high pressure arteries to the

of a group of cells (myocytes) positioned on the wall of the right atrium‚ at the center of the heart and near the entrance of the superior vena cava. The sinoatrial node coordinates beating of all four chambers of the heart. It stands to reason that this coordination would begin in the first chamber involved and travel to the rest in sequence. 3.
