A drug or substance the effects heart muscle contraction.
An inotropic effect refers to the ability to alter the force of muscle contractions, such as in the heart. A positive inotropic effect increases contractility, while a negative inotropic effect decreases it. On the other hand, a chronotropic effect refers to the ability to alter the heart rate. A positive chronotropic effect increases heart rate, while a negative chronotropic effect decreases it.
Examples of inotropic drugs include digoxin, dobutamine, and milrinone. These drugs work by affecting the levels of calcium inside heart muscle cells, leading to increased contractility and force of contraction. Digoxin inhibits the sodium-potassium pump, increasing intracellular calcium levels, while dobutamine and milrinone increase calcium availability in the heart muscle cells.
Depending on the context, effect is already a verb. For example, "to effect something" or to "make something have effect" is an action and therefore a verb.
effect
No, the reverse process of the photoelectric effect is not the Zeeman effect. The Zeeman effect is the splitting of spectral lines in the presence of a magnetic field, while the photoelectric effect is the emission of electrons from a material when exposed to light. They are two distinct phenomena in physics.

No, they are drugs that counteract the effect of catecholamines between synapses and suppress inotropic effect of the heart muscle
inotropic agent like digoxin help contract the heart muscles
No. It is a positive inotropic because it promotes anabolism.
Inotropic refers to the force of contraction of the heart muscle, while chronotropic refers to the heart rate. Inotropic agents affect the strength of the heart's contractions, while chronotropic agents affect the heart rate.
Inotropic agents example are positive inotrops- digoxin, adrenaline, nor adrenaline,dopamine,dobutamine, amrinone, etc.
Calcium has no effect on heart rate. It does, however, have an effect on how hard the heart squeezes (inotropic effect). Heart rate is effected by the slow sodium channels in the pacemaker cells in the right atrium (and other pacemaker cells if the SA node is malfunctioning).
Digoxin is primarily an inotropic agent, meaning it helps to increase the contraction strength of the heart muscle. It can also have mild effects on chronotropy (heart rate) and dromotropy (conduction velocity) by slowing down the heart rate and conduction through the atrioventricular node.
increases the contractility of myocardial fibers
It's a medication that affects contraction of muscle tissue, most notably the heart.
Michael Artman has written: 'Developmental Changes in Myocardial Inotropic Responsiveness'
Inotropic drugs affect the force of contraction. Chronotropic affect the rate of contraction.
