What decreases at a slower rate CO or CI?
what happens to the HR is old farts?
the Maximum HR decreases about ____% per decade after the age of 50?
what happens to conduction time in the older population?
the sympathetic response in HR decreases in the elderly b/c of what?
a decreased number of sympathetic receptors
*** decreased CO and HR lead to what?***
Increased circulation time
**** Sincce the decreasd CO and HR lead to increased circulation time, what does this mean to our pt's? ****
drugs take longer to circulate
What happens to BP with age?
The mean systolic BP reaches approximately what by age 70?
