[Novel assessment of intracellular calcium transient decay in cardiac muscle by curve-fitting with half-logistic function].

open access: closedMasui. The Japanese journal of anesthesiology, 2008
A decrease in intracellular calcium (Ca2+) concentration in the cardiac muscle is one of the important factors to induce myocardial relaxation. A mono-exponential (m-E) function has been used for assessing myocardial relaxation curve of isometric tension and intracellular calcium transient (CaT) decay, and the m-E time constants for the relaxation ...

Evaluation of cardiac function and venous return curves in awake, unanesthetized cialves with an implanted total artificial heart.

open access: closedTransactions - American Society for Artificial Internal Organs, 1975
1) The implanted TAH offers a method of evaluating the effects of varying physiologic demands cardiac output and venous return. 2) Cardiac output and venous return measurements offer a method of evaluating system design of the device and driving and control-logic improvements in awake, unanesthetized animals. 3) The obtained cardiac function and venous

Cardiac Output Response to Norepinephrine in Postoperative Cardiac Surgery Patients

Critical Care Medicine, 2013
We studied the variable effects of norepinephrine infusion on cardiac output in postoperative cardiac surgical patients in whom norepinephrine increased mean arterial pressure. We hypothesized that the directional change in cardiac output would be determined by baseline cardiac function, as quantified by stroke volume variation, and the subsequent ...
