Hey!

Both are under graduate courses after 10+2 of 3-4 years with 2 semesters per year. In cardiovascular technology, candidate becomes the physician of the invasive cardiovascular testing. Means, one who does treatment/operations of patients. While in cardiology, you basically learn the process to assist the physician during operations or one who does work on the medical tests/ reports of the patient's heart.

Hope it helped to clear your delimma.

Thank you.
