A client with a history of having several myocardial infarctions has excessive filling of the ventricles as a result. What physiologic response would the nurse expect to see manifested in this client?
A. Excessive LVED (left ventricular end-diastolic) volume and decreased cardiac output
B. Reduced LVED volume and increased cardiac output
C. Excessive impedance of the left ventricle
D. Reduced impedance of the left ventricle
A
According to Starling's law, the more the heart is filled during diastole, the more forcefully it contracts. This is true, within limits. Overstretching or excessive filling of the ventricles results in excessive LVED volume and pressure and decreased cardiac output.
