Cardiac Function Flashcards
What is the equation for CO?
CO=HR x SV
with activity what happens to
HR
SV
CO
SBP
DBP
HR increases
SV increases
CO increases
SBP increases
DBP stays the same
MAP equation
MAP= DBP + 1/3 (SBP-DBP)
how does HR change with training
with training HR decreases
Can an anginal threshold change?
very unlikely to change
What can you do to improve or change in a case of a pathology affecting the heart?
lower HR and BP
allow someone to be more conditioned
with training heart rate decreases at any given workload
5% of adults over 65 have a-fib what are some things to think about with this patient
worried about throwing a clot- make sure they are on anti-coag
What is uncontrolled Afib and controlled afib
uncontrolled >100 bpm
controlled up to 100 bpm
what are some ways we can assess whether the heart is doing its job?
Signs
HR
BP
double product (HRx SPB)
EKG rate/rhythm and ST level- specific to cardiac problems
what is the target on the borg scale in pulmonary rehab
4-6
