Please look into Postural Orthostatic Tachycardia Syndrome (POTS). It is a very unheard of nervous system disorder that prevents the body from being able to properly adjust to gravity. It causes many symptoms, primarily rapid heart rate and dizziness. I was finally diagnosed last year after six years of suffering, wondering, and incorrect diagnoses.
Feel free to ask any questions, or just chat. I wish you the best.
