er...why are you worried about your systolic based on those readings Dereck?
Anything from 110-140 is normal, 140-160 is borderline, and 160+ is clinical hypertension.
Also, the systolic reading is a constant state of flux anyway, and from a medical perspective, the diastolic reading is of much greater value. Here, 70-85 is normal, and anything higher than 90 is clinicaly hypertensive.
Considering than the baseline readings increase with age, your BP is absolutely superb at the moment Dereck. If this is being controlled with medication, then its working, and if its just you naturaly, then you are displaying zero sign of cardiovascular issues in regard to these readings.
