AS a QA what are the points needs to be tested for Healthcare applications?

I was joined in Healthcare company in last month. As I'm new for this domain I had never handled any healthcare applications before. I'm having experience in E-commerce, ERP, Banking domains and Now I want to work with Healthcare.

When I started with KT of new applications some words are new for me where I was never heard before like, Endoscopy, IVF, Pathology,Inventory etx.

AS a QA what are the points needs to be taken care at the time of testing either Manual or Automation in Healthcare domain.
