Intuitively, why does a stronger heart cause blood pressure to go down? The answers I've found from a cursory google search seem to indicate that it has to "work less hard" to pump the blood and that it "beats more slowly," but I do not immediately understand the implications of this.
Furthermore, if it is due to a slower heart beat in a stronger heart that blood pressure is lower, then how does (/is it true that) blood pressure remains lower in those with a stronger heart during exercise? Wouldn't a stronger heart beating just as fast as a weaker heart lead to higher blood pressure?
Thanks for any help. :)
