Web- it inhibits the Na+/K+ATPase pump, increasing intracellular Na+, which in turn produces inotropy. - this is because the Na+/Ca2+ exchanger uses Na+ to power Ca2+ efflux. … WebWhen Dr. Desai talks about the Ca2+ coming into the cell more quickly due to sympathetic neurotransmitter activity, this is an inotropic effect. I wouldn't call it a side effect, it is the …
WebAnaesthetic agents cause vasodilation and some negative inotropy (contractility), leading to a transient drop in BP mostly from redistribution of blood and reduced venous return (pre load).
