PhysioEX notes Autorhythmicity- heart’s ability to trigger its own contractions Phase O- a lot like depolarization in neuronal action potentials. Sodium channels open‚ increase of sodium INTO cell. Phase 1- sodium channels close‚ potassium channels close‚ decrease in potassium and sodium. Calcium channels open‚ increase of calcium into cell. Phase 2- Plateau phase‚ membrane still depolarized (contract). Potassium channels closed‚ L-type calcium channels stay open. Lasts 0.2 seconds/200
