Also, "not secondary to anxiety" means that the anxiety is not causing the rapid pulse when positional changing.
Cashe2, just a little advice. If your insurance allows you to change your PCP, please change your FD to an Internal Medicine Doctor, they have all the skills of a family doctor but are specialist where it counts the most: Diagnoses and medicines.
Thanks so much!
"POTS patients often have anxiety and a lot of other unexplained symptoms, but the rapid pulse with positional changes is NOT secondary to anxiety"
What does "not secondary to anxiety" mean?
Postural orthostatic tachycardia syndrome (POTS) presents primarily with symptoms from changing position from seating to standing (orthostatic symptoms), pulse greater than 100 (tachycardia) , and the absence of significant low blood pressure (hypotension.) The symptoms arise from the brain not getting enough blood and by activation of stress hormones. POTS affects females 5 times more often than males, and most patients are between 20 and 40 years old. POTS can cause a wide variety of different symptoms though. Often no 2 POTS patients have the same symptoms.
Diagnosis of POTS is controversial, but some of the criteria include things you mentioned:
-Orthostatic tachycardia with change greater than 30 beats per minute (bpm)
-Drop in blood pressure (BP) of more than 20 mm Hg
-Severe orthostatic symptoms
POTS patients often have anxiety and a lot of other unexplained symptoms, but the rapid pulse with positional changes is NOT secondary to anxiety. It is a change in their body that helps keep their blood pressure normal when blood pools in their veins.
This condition is best evaluated by TILT TESTING. You should ask your physician to refer you to a cardiologist who performs this type of testing and has this specialized equipment. Some electrophysiologists (type of cardiologist) evaluate this condition.
Depending on the findings of tilt testing a number of different treatments are available. Treatment includes increasing the amount of volume of fluid in the arteries and veins with salt and fluids. Compression garments are also helpful. Low doses of medications like beta blockers and vasoconstrictors (midodrine, etc.) can also be used guided by results of tilt testing.
Thank you for your excellent question.
