One More Clarification On Pots Diagnostic Criteria

During my tilt tests the increase in my heart rate ranged from 22bpm to 60bpm increase. Within the 1st minute the increase was 37bpm, then it dipped down to 22bpm (while my blood pressure increased), and by the end was up to a 60bpm increase. It seems to be a similar pattern during my 'poor man tilt'-meaning it shoots up, drops and then significantly jumps at the end of 10minutes.

I did receive word today that I have an appointment with a Neuro at U of Denver who specializes in Dysautomonia in February. Until then, thank you for all your knowledge and help!

Hey Blue Skies-

I technically don't know the answer to your question- it's a good one. BUT from my interpretation, if at the end of 10 mins, your HR has increased by 60 bpm- you have POTS. Hope the specialist can help.

I agree with Julie. And I notice somewhat of the same trend when I take my orthostatic BP/pulse. My BP will dip and my pulse will increase by 40 bpm or so for the first 2 minutes, then pulse will dip 10 bpms or so and BP will go up for a minute or so, after which my BP will rise and my pulse will continue to rise slowly until it becomes too uncomfortable for me to stand. It's normal for our bodies to try to compensate for decreased bloodflow to our brains on standing by increasing our peripheral vascular resistance by raising BP, which usually lowers heartrate also. The abnormal part is when our heartrate doesn't continue to return to baseline but rises to 30bpms or more when we've been standing for a couple minutes or longer. That indicates a problem somewhere!

I get exactly the same as this too. So we're all in the same camp.

Your rise in HR (30 or more) can happen at any time during the first 10 mins of TTT or poor man's tilt. Your HR doesn't have to stay high. Mine tends to peak then start to drop again, it may peak more than once as we often have labile heart rates.
