Table 1.02. Factors affecting heart filling

RIGHT ATRIAL FILLING DEPENDENT UPON VENTRICULAR FILLING DEPENDENT UPON
* skeletal muscle pump * atrial contraction
* respiratory movements * passive blood flow
* venous tone (compliance) * active ventricular relaxation (negative luminal pressure)
* posture * pericardial restraint (stiffness)
* downward movement of ventricular during systole * ventricular compliance
