Advice? Undiagnosed

Haven’t been diagnosed but joined this group bc I think I may have this as I have some symptoms. When I sleep my heart rate is around 60BPM which is good. When I get up to go to the bathroom it will jump to 110-120. Throughout the day it will be 85-120 just moving around. If I do cardio & running at the gym it’s 150-200. Is this normal? Do I have anything to worry about? I see some posts saying they are 160 just laying down, that doesn’t happen to me. Should I get testing done? What does testing consist of?
