Cardiac System
Conduction of the heart
2 main phases
diastole
when the heart chambers relax and fill with blood
systole
when the heart chamber contract and empty the blood
myogenic
heart creates its own impulse
4 key areas
Atrio-ventricular node
Bundle of his
Sino-Atrial node
Purkinje Fibres
content for exam question
heart is myogenic
Sino-atrial node creates impulse
causes atrial systole
impulse travels to atrio-ventricular node
short delay for ventricular diastole
travels to bundle of his
impulse split to left and right side
travels up Purkinje Fibres
causing ventricular systole
