Hello doctor! How should APSO congenital heart disease be treated (please advise me tomorrow at 2 o'clock). Thank you doctor for helping me!

I am 34 years old this year. I just found out I have APSO 4 congenital heart disease, now I'm on medication. For the past few days, I've been feeling nervous and my heart beat fast. I want to ask the doctor: What are the symptoms of APSO 4 disease?
