Tachycardia
abnormally rapid heart rate - above 100
Bradycardia
abnormally slow heart rate - under 60
preload
volume of blood in ventricles at end of diastole
Afterload
resistance against which left ventricle pushes blood out
, Systole
contraction of heart .... provides increase in pressure to eject blood
Diastole
relaxation of heart.... required for filling chambers

hypervolemia, regurgitation of cardiac valves, heart failure
When is afterload increased?
hypertension, vasoconstriction
What increases when afterload increases?
increase in cardiac workload
