Thanks for your question on Healthcare Magic.
I can understand your concern.
No you should not take any thing which is having caffeine.
So don't take that tablet (oxylite).
Yes, your doctor is right. You should reduce
stress, quit
smoking and avoid caffeine totally.
But if still feel symptoms like palpitations,
chest pain,
chest tightness, pressure etc then immediately
consult cardiologist and get done Holter monitoring (24 hours continuous recording of ecg).
Radio frequency ablation (RFA) is the treatment of choice if patient is symptomatic despite of conservative treatment.
At young age, RFA is having excellent results.
So consult cardiologist and discuss all these.
Don't worry, you will be alright.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
