Cardiovascular nurses care for people with heart disease and interact with their patients' families. They may monitor and treat acutely ill patients, or they may focus on cardiac rehabilitation—helping patients make lifestyle changes to prevent the worsening of their disease.

Electrocardiograph (EKG) Technicians are medical practitioners who administer tests to determine the cardiovascular health of patients. Their primary duties include performing diagnostic tests on patients, monitoring patient blood pressure and collecting medical data for use by doctors.
