Hello, I m 24 years old and was diagnosed with SVT, and generalized anxiety disorder when I was 18. I m used to my heart racing sometimes, palpitations, PVCs, ect. However lately my blood pressure has been spiking up to about 150/90 or so and i get a pain that comes along with it that feels like im getting an IV in my heart. My normal BP is around 118/60 or so. Do you think these spikes are stress related? I have also been getting fatigued much more quickly when on the tread mill, and sometimes when lifting much weight i frequently have to rest due to chest pain . I had a tread mill stress test done a few weeks ago and my heart rate went up to about 196bpm after only 11 minutes or so. My blood pressure did not re adjust normally but the doctor didn t have much to say about it. On an echocardiogram I got when i was 18 it showed diastolic dysfunction stage 1, as well as mitral valve prolapse . My cardiologist also said that was nothing to worry about. However, it just feels like my heart is generally getting weaker over time. What can I do about this?
