We used a cylindrical model for the left ventricle contracting both radially and longitudinally to show how the ejection fraction is related to different variables that describe the ventricularâ€¦ (More)

The concept of external work reserve (EWR) related to the end-systolic pressure-volume relation in the left ventricle and introduced in previous publications is investigated. The potential clinicalâ€¦ (More)

On the basis of a mathematical formalism derived in previous studies, properties of the end-systolic pressure-volume (P-V) relation were analyzed to define indexes that can characterize a normal orâ€¦ (More)

The JaffÃ© reaction for creatinine assay appears to follow pseudo-first-order kinetics; first-order rate constants are different for different samples. Rate constants for 10 different serum samplesâ€¦ (More)

The concept of body force (force/unit volume of muscle), which has been suggested as an explanation for the mechanical contraction of the left ventricle, is now applied to the right ventricle. Theâ€¦ (More)

A mathematical approach is given by which the intramyocardial stress sigma induced in the passive medium of the myocardium is expressed as the sum of the stress (sigma)p induced in the passive mediumâ€¦ (More)
