Explanation:
Detailed explanation-1: -Next, the signal travels to the AV node, through the bundle of HIS, down the bundle branches, and through the Purkinje fibers, causing the ventricles to contract. This signal creates an electrical current that can be seen on a graph called an electrocardiogram, or EKG.
Detailed explanation-2: -An impulse can be generated either from the Bundle of His, Bundle Branches or Purkinje Fibres at an intrinsic rate of 20 – 40 bpm.
