Dear Khanam 

Preliminary findings reveal that Osmania University or its affiliated colleges do not offer a bachelors degree in Cardiovascular Technology. If by Deccan College, you are referring to Deccan College of Medical Sciences, Hyderabad or Deccan College of Engineering and Technology, then even that college doesn't offer a degree in the same. Many colleges in Osmania University offers related courses in Biotechnology, Microbiology, Biochemistry, etc.

Cardiovascular technologists, on the other hand, assist physicians in timely diagnosis and treatment. It is a four-year course and requires PCB as subject combination in Class 12 for admission. Some of the reputed colleges offering this course include CMC, Vellore, Manipal University, Amrita Vishwa Vidyapeetham, Hamdard Institute of Medical Science and Research, et.al. 

Hope it answers you. 

All the best!
