Three of the courses you have mentioned are good for professional who want to go for Paramedical courses.

Now if you tell me to prioritize then I would say-

• Dialysis technology
• Cardiac technology
• Physician Assistant

The reason for such ratings is employability. If you are considering for only BSc then you will have more openings in Dialysis technology rather than any of the two. But if you are wiling for Master course then go for Cardiac Technology as the pay packages are much better in this field.
