Cardiac Anatomy - The heart is the size of a closed fist



2/3 of the heart is to the left of the midline

1/3 under the sternum

, heart layers - Endocardium ( inner)

myocardium ( middle)

Pericardium ( outer)



Cardiac action potential: phase 0 - rapid depolarization

Sodium influx d/t voltage-gated sodium channels opening



Cardiac action potential: phase 1 - initial repolarization of cells

voltage gated sodium channels closed

voltage gated potassium channels open

Potassium leaves cell slowly



Cardiac action potential: phase 2 - plateau phase

voltage gated calcium channels open

influx of calcium into the cell

balances potassium efflux

calcium influx triggers more calcium from sarcoplasmic reticulum > myocardial contraction



Cardiac action potential: phase 3 - Rapid Repolarization w/ potassium efflux

voltage gated potassium channels open

voltage gated calcium channels close



Cardiac action potential: phase 4 - resting membrane potential, -85 mV

High potassium permeability from the potassium channels



Potassium imbalance affect on myocardial action potentials - Hypokalemia-increased atrial preload leads
to 1-3 degree blocks

Hyperkalemia-slows depolarization, leads to sunus bradycardia and junctional rhythm
