Hii

If i give you clear information so for M.Sc Echocardiography, most Deemed Universities require candidates to have completed:
- MBBS, B.Sc in Cardiac Technology, B.Sc. in Allied Health Sciences, B.Sc. in Nursing, or Equivalent in Life Sciences.
- But BAMS is generally not considered as eligible Qualification

Still, eligibility rules vary by deemed university. Maybe some private universities has BAMS as eligibility criteria.
You should check eligibility criteria on University's official Prospectus.

After completing BAMS, you may not be directly eligible for MSc Echocardiography, as most universities prefer candidates with a background in B.Sc Cardiac Care Technology, B.Sc Echocardiography, Nursing, or MBBS. Since BAMS is not usually listed in the eligibility criteria, you may face difficulty getting admission into this course. However, some private or deemed universities may consider your application if they allow medical graduates from AYUSH backgrounds, so it is better to confirm directly with the university before applying.

All the best!
