The commitment of cells to pacemaker cell fates and their capacity to differentiate into pacemaker cells. Pacemaker cells are specialized cardiomyocytes that are responsible for regulating the timing of heart contractions. The commitment of cells to atrioventricular (AV) node cell fates and their capacity to differentiate into AV node cells. The process whereby a relatively unspecialized cell acquires specialized features of a pacemaker cell. Pacemaker cells are specialized cardiomyocytes that are responsible for regulating the timing of heart contractions. The process whose specific outcome is the progression of the atrioventricular (AV) node over time, from its formation to the mature structure. The AV node is part of the cardiac conduction system that controls the timing of ventricle contraction by receiving electrical signals from the sinoatrial (SA) node and relaying them to the His-Purkinje system. The process whereby a relatively unspecialized cell acquires specialized features of an atrioventricular (AV) node cell. AV node cells are pacemaker cells that are found in the atrioventricular node. The commitment of cells to specific cardiac muscle cell fates and their capacity to differentiate into cardiac muscle cells. Cardiac muscle cells are striated muscle cells that are responsible for heart contraction.
