Cardiac cellular action potential - Answer The cardiac action potential is a short-lasting event in which the membrane potential (the difference of potential between the interior and the exterior) of a cardiac cell rises and falls following a consistent trajectory, similar to the action potential in other types of cells. Cardiac action potentials are generated by the movement of ions through the transmembrane ion channels in the cardiac cells. Phase 4 is the resting membrane potential, an...

You respond to a residence for a 68-year-old male with nausea, vomiting, and blurred vision. As you are assessing him, he tells you that he has congestive heart failure and atrial fibrillation, and takes numerous medications.
