In the myogenic response, ________.a. muscle contraction promotes venous return to theheartb. ventricular contraction strength is decreasedc. vascular smooth muscle responds to stretchd. endothelins dilate muscular arteries
Beta blockers are used to reduce heart rate in cardiac patients. They slow down the heart rate by reducing the conduction of action potentials through A-V node. How would the effect of beta blockers be reflected on an ECG? Don't copy
