8. Even though it is trivial that Beta Blockers might have negative inotropic effect on theheart, but they improve the overall heart function in heart failure at the end and used forthis condition, because:a. They decrease reflex overload of the heartb. They inhibit RAAS systemc. They decrease after loadd. They slow electrical conduction of SA and AV nodes which increases the filling timeof the ventricles which improves extraction fraction in HFFEFe. All of the above

Beta-blockers act on the Beta 1 receptors which are located in the heart and it slows down the…

Answered: Even though it is trivial that Beta…
