Thank you for putting your trust in us to answer your query.
I would like to clarify a few things
1) were you investigated for
SUPRAVENTRICULAR TACHYCARDIA. if so, what was the cause.
2) what medications are you on for asthma nd
psoriatic arthritis.
3) hare you had a workup to rule out cardiac(heart) disease,
hypertension, and diabetes, if so, what were the results?
I recommend you to stop exercising until you get cleared by your physician to continue to do so.
exercising seems to be putting a strain on your heart and we need to find out the reason.
Ablation will help only if an extra nerve bundle is present , which is responsible for the SVT. Other causes of SVT need to be ruled out.
certain medication no for asthma can cause tachycardia( fast
heart rate).
Undertreated asthma could also cause tiredness and
chest pain.
I recommend you see your physician to arrive at the proper diagnosis so that you can get better soon.
hope I've helped.
feel free to ask if you need any clarification.
wish you good health
