A review of the material for Principles III test 1. Reviewing cardiac material.
Systole
Bradycardia
Diastole
None of above, blood flow to coronary arteries is constant
Perfusion will increase due to an increase in cardiac output.
Perfusion will decrease do a decrease in filling times.
Perfusion remains the same because the decrease in diastolic filling time and increase in CO roughly balance each other out.

Voltage dependent increase in sodium and potassium
Potassium increases and slow calcium channels close.
Sodium increases and potassium decreases
Slow calcium channels open and calcium increases
