What is the conduction system of the heart SA node, atrial, AV node, bundle of his, right bundle branch, left bundle branch, Purkinje fibers, ventricular polarization
Two types of cardiac cells Electrical and mechanical
Automaticity cardiac cells to generate impulses without any external stimulus
Conductivity Ability of cardiac cells to relay and impulse to neighboring cells
Excitability To respond to stimulus
Contractivility cardiac cells to respond to stimulus and then contract
Action potential Difference between electrical charges across cell membrane which result in depolarization and repolarization
One cardiac cycle equals Five waves
Refractory period Cells cannot respond to any stimuli
Distance between two waves Segment
Interval Wave plus a segment
Intensity of current Gain
Converts electrical impulses into mechanical Galvanometer
