WebApr 10, 2024 · Ans: The action potential of the cardiac cells of the sinu-auricular node (SA Node) is a brief change in the potential or voltage in order to convey a stimulus for beating the auricles and ventricles continuously. This action potential is produced nearly 60 to 100 times in the SA node within a minute resulting in the heartbeat rate of a person.
