2. HR response to standing
3. HR variation with respiration
4. sweat test
What is the normal response to standing up or tilting forward?
BP will drop 10/20 mm Hg anything higher is abnormal
What is the normal response to heart rate when standing?
increase 11-90 beats per minute
What is the normal response to HR variation with respiration?
initial increase in rate, but their is a rapid decrease
what is the normal response to the sweat test?
sweat is present all over body and limbs
what is being tested when doing the standing up or tilting forward test?
afferent and sympathetic efferent limbs
what is being tested when doing the standing up standing test?
parasympathetic (vagal) afferent and efferent limbs
what is being tested when HR variation is being tested with respiration?
vagal afferent and efferent limbs
what is being tested during the sweat test?
sympathetic efferent limb
how can the sympathetic efferent pathways be further tested?
