I am a doctor and perform HRV testing. When performing the orthostatic test, one of the paramaters that is measured is heart rate. For example, A 53 year old woman has a supine HR of 83 And an pright HR of 105. This is a 26% increase. My work is primarily in functional and optimal ranges of values, not merely patholgical states. My Question: What is the functional range of HR increase in an orthostatic test using HRV. I am concerned that she has insufficient vascular compensatory recovery or her heart is deconditioned.
Hello, A 30 beats per minute increase in heart rate from supine heart rate within 10 minutes of standing from a supine position along with symptoms of postural hypo-tension is indicated as significant and is labelled as postural orthostatic tachycardia. If the case is so (not in your case), you should work-up for its causes like hypokalemia, diabetes, autoimmune disease, autonomic nerve dystrophy, multi system atrophy etc. Hope I have answered your question. Let me know if I can assist you further.
