Pacemaker and muscle cells are the two types of cardiac cells
Barorecptors detect stretching
Epinephrine increases the heart rate
Stroke volume measures the amount of blood
Inotropes influence the force of contraction
A normal heart rhythm is a sinus rhythm
Afterload is the pressure the heart generates to eject blood at systole
Preload occurs at the end of diastole
The signal travels to the bundle of His after the AV node
Pacemaker cells make up the conduction system
Muscle cells perform contraction Squeezing muscles
Cardiac output measurement is based on the ventricle Oxygenated blood leaves through the left side
