CARDIAC OUTPUT-DETERMINANTS OF EDV
From NeuroRehab.wiki
SUMMARY
REDUCED END-DIASTOLIC VOLUME
1. Reduced ventricular compliance (e.g. MI, infiltrative disease).
2. Pericardial effusion.
3. Reduced venous return to heart, e.g. standing.
INCREASED END-DIASTOLIC VOLUME
4. Stronger atrial contraction.
5. Negative intra-thoracic pressure during inspiration.
6. Increased venous return to heart, e.g. muscle pumps during exercise.
