We also continued work with ryanodine, which produced a negative inotropic effect on the guinea-pig atrium and actually changed the force-frequency effect from a positive to negative staircase
-
We also reported on the effects of anaerobiosis and of a number of positive and negative inotropic agents.
-
We showed that the positive inotropic effects of norepinephrine and strophanthin-K were correlated with an increase in rate of exchange of calcium in an intracellular pool associated with the contractile process and that the negative inotropic effects of acetylcholine and adenosine were correlated with a decrease in rate of exchange in that pool.
-
We collaborated with my good friend William Sleator of the Physiology Department in the study of changes in cellular action potentials (measured with intracellular microelectrodes) associated with the changes in contractility of the guinea pig atrium in response to epinephrine and acetylcholine, and a number of other inotropic agents.

Patients with heart failure, chronic coronary artery disease, or cardiomyopathy should take D-ribose to offset the energy-draining effects of inotropic drugs such as digoxin.

Apelin, a newly described inotropic peptide (related to the force of heart muscle contraction) with important cardiovascular regulatory properties, contributes to functional improvement in patients with severe heart failure after they have undergone implantation with bone marrow mononuclear cells (BMMC).

ICa than was needed for CCh's negative inotropic effect on atrial muscle suggesting that neither IK, CCh nor ICa alone can mediate CCh's actions but they might synergistically reduce

qms commented on the word inotropic
If a heart has a feeble or slow tick
There's a tried and a true medico trick.
They virtually seize it
And rhythmically squeeze it
With drugs that are called inotropic.
