Webb28 apr. 2024 · Phase 1 of the cardiac action potential. Phase 1 is characterized by a brief initial repolarisation which occurs as the voltage-gated sodium channels close. It is also called the "notch". The action potential is said to approach zero during this period, but some authors (Santana et al, 2010) mention that the membrane potential bottoms out at ... WebbThe first phase of the action potential is the rising phase called ‘depolarization’, which occurs due to a stimulus and causes the opening of voltage-gated sodium channels. The …
