Working out with palpitations

[Mike_lfc_92]

I've had palpitations for 3 years since i had my first anxiety symptoms. The anxiety has gone but the palpitations remain and i've had tests on my heart etc but im fine apparently. is it safe for me to work out? because even when i run up the stairs i am fucked + my lungs are working harder due to the palpitations and i struggle to catch my breath.
