What are the other potential pacemaker cells in the heart?
Besides the SA node, other myocardial conducting cells can potentially act as pacemakers. These include cells in the atrioventricular (AV) node, the atrioventricular bundle, and the Purkinje fibers. However, these cells usually do not control the heart rate because their inherent rhythm is slower than that of the SA node.
