Physiology
Cardiac Cycle
- Five phases
- Atrial systole: only responsible for 30% of ventricular filling
- Isometric ventricular contraction
- Ventricular contraction
- Isometric ventricular relaxation: rapid passive filling of the ventricles occurs in early diastole
- Ventricular filling
- Contraction is asynchronous
- Right atrial contraction before left
- Left…
