How is this reflex in humans affected by beta blockers?
- robbiep 11y agoLogically, if your heart is already slow then it is going to have a hard time going slower (ie you are already blocking sympathetic drive and when sympathetic drive decreases further via the reflex it isn't going to change much). Since beta blockers are largely beta 2 selective these days it shouldn't affect capillary vasoconstriction, although since the article specifically mentions capillary over arteriolar vasoconstriction I don't know whether that is accomplished by adrenoceptors or what particular receptor is responsible. So: no or minimal change to heart rate, likely unchanged effect to vasoconstriction
