Study Notes
Cardiac Output (CO)
- Formula for Cardiac Output (CO): CO = Heart Rate (HR) × Stroke Volume (SV)
Ventricular Volume
- End Diastolic Volume (EDV): the final volume in the ventricle at the end of diastole
Stroke Volume (SV)
- Normal range for Stroke Volume (SV): 60-100 mL
Cardiac Contraction
- Inotropy: the force of mechanical contraction in the heart
Preload Effect
- Increase in preload: increases stretch of cardiac muscle, leading to increased contraction force and stroke volume
