Chest pain. Help is much appreciated.

Hi All, I am Rohit from Delhi, In Dec last year i had chest pain, So took a ECG and Doctor's suspect type1 Brugada morphology. After this I have done multiple ECG, ECHO, TMT, CT Angiography and holter test for 24 hrs all these test came negative, So Doctor told its asymptomatic, Since there was no ventricular tachycardia (VT) or ventricular fibrillation (VF), or a family history of sudden cardiac death in a first degree relative who is less than 45 years old and no treatment was provided. Now i am planning to get married, I want to confirm i am having Brugada syndrome, Can I under go a Flecainide/Ajmaline challenge challenge test to confirm I have Brugada syndrome. If yes can you please let me know which hospital in India these tests are done, I am staying in New Delhi as of now. This help is much appreciated. Thanks in Advance. -Rohit
