welcome to healthcare magic
as your boyfriend suffers from svt
, a whole cardiology checkup would be of benefit,
an ecg,an echo, a stress
ecg test, holter ecg, so know when he gets his attacks of svt.
other thing is he needs to change his diet do exercise and cope with the stress he is undergoing because all these are risk factors that can trigger a heart attack
he needs to be checked if he has any symptoms of heart failure
because of the shortness of breath
needs regular check ups with his blood pressure as the symptoms he might be experiencing could be due to his pressure going high
would suggest take him to visit a cardiologist for a through check up and put on treatment as he is having problems despite having a genetic problem
hope have been able to answer your query
hoping for your boyfriend quick recovery.
