Hyperadrenergic POTS

... and legs . POTS is most frequently seen in young women, often less than 35 years of age. Hyperadrenergic POTS is defined as POTS associated with a systolic BP increment ≥10 mmHg during 10 minutes of HUT, and an orthostatic plasma norepinephrine ≥600 pg/mL. As a part of the definition, POTS is associated ...

... each beat divided into 24 intervals for analysis. The end diastolic radioactivity detected from the left ventricle was 6400 counts and the end systolic was 3600 counts. Upon calibration the heart was found to eject an average of 50mls per beat. During the procedure, 1.Michael's average heart ...

Re:

How would you know? A blood pressure reading is just a reading of high pressure and low - it's assumed the high is systolic...watching the gauge, the high pressure matches the pulse, but that would happen if some weird reverse was true also. One might imagine a condition where osmotic ...

Re: Can Systolic BP ever be less than Diastolic?

I don't think that's possible. I mean, strange things happen - people have a heart on the right side, instead of left - but systolic blood pressure being lower than diastolic blood pressure just doesn't make sense. Systolic blood pressure - When the heart shrinks and pushes the blood ...

Can Systolic BP ever be less than Diastolic?

It is possible, kinda. Remember that systolic pressure is the pressure measured during ventricular contraction pushing blood out into the system. Diastolic pressure is the pressure when the ventricle is not pushing. Now, if you have a region ...
