The job duties of a cardiology nurse practitioner involve providing care to patients in a cardiovascular clinic or department. While their responsibilities may vary by employer, a nurse practitioner can typically perform their duties without direct supervision. A cardiology nurse practitioner may help examine cardiovascular patients, order tests, make assessments, educate patients on their therapeutic options, and monitor the condition and heart health of patients that have pacemakers or other ICDs. The qualifications that you need to start a career as a cardiology nurse practitioner include an advanced degree, a license to practice in your state, and clinical experience in cardiovascular care.
