Explanation:
Detailed explanation-1: -Phases of the Cardiac Action Potential. The cardiac transmembrane action potential consists of five phases:phase 0, upstroke or rapid depolarization; phase 1, early rapid repolarization; phase 2, plateau; phase 3, final rapid repolarization; andphase 4, resting membrane potential and diastolic depolarization (Fig.
Detailed explanation-2: -Step 1: Pacemaker Impulse Generation. The first step of cardiac conduction is impulse generation. Step 2: AV Node Impulse Conduction. Step 3: AV Bundle Impulse Conduction. Step 4: Purkinje Fibers Impulse Conduction. 24-Jun-2019
