1) Know the mean Central Aortic systolic pressure in POTS patients.
2) Determine the systolic blood pressure, diastolic blood pressure, pulse rate, mean arterial pressure
in POTS patients.
Background: POTS is a form of orthostatic intolerance that is associated with the presence of
excessive tachycardia and symptoms like fatigue, headaches, lightheadedness, heart palpitations, exercise
intolerance, nausea, diminished concentration, tremulousness (shaking), syncope (fainting), coldness or
pain in the extremities, chest pain and shortness of breath upon standing. We had previously reported a
paper demonstrating that POTS patients have lesser dimensions and high blood flow velocity in Aorta.
Central Aortic Systolic Pressure (CASP) is the blood pressure at the root of the aorta or the largest artery
in the body, as the blood is being pumped out of the heart. CASP has been shown to be an important factor
in the relation to strokes and cardiovascular events, more so than the brachial pressure or the pressure at
the arm commonly. The aim of this study is to determine the Central Aortic Systolic Pressure, Systolic
Blood pressure, Diastolic blood pressure, Pulse rate, Mean arterial pressure in POTS patient.
Methods: 56 Pots Patients from our clinic has CASP measurement performed. A device
equipped with a wrist sensor module which is to be worn on the patient's wrist for blood pressure
measurement. The sensor module is designed based on the concept of the BPro device which looks similar
to a watch-like device and can be worn easily on the radial artery for measuring blood pressure noninvasively. The sensor's position is maintained by applying a consistent tension on the artery.
Results: Out of 56 patients, 98% were females (n=55 age 30.58±10.80) and 2% were male
(n=1,age 29).Our findings in mean ± standard deviation, Mean Arterial Pressure 92.42±9.69, Central
Aortic Systolic Pressure (CASP) 110.17±11.63,SBP 120.44±11.29,DBP 81.31±9.34,Pulse Rate
83.08±11.96.
Conclusion: CASP were normal in POTS Patients.
