nana1 Posted May 10, 2014 Share Posted May 10, 2014 Quick question:Would an increase in sympathetic activation of SA node cells lead to an increase in stroke-volume?For example, wouldn't increased sympathetic activity from exercise increase SA activity which would increase amount of contractions which would then strengthen the heart and then make contractions stronger?If you can provide any sources to show this would be great. Thanks for the help in advance! Link to comment Share on other sites More sharing options...
