Thanks for your health concerns. The numbers you show are not too concerning, except for the fact that the systolic blood pressure (top number) might be expected to be higher at full exercise; it could be perhaps that your hydration status was not adequate and that caused some dizziness
. Hydrate appropiately, and if symptoms are recurrent then I would seek your medical provider for examination and testing.
