A telemetry nurse cares for patients with heart conditions and high blood pressure as well as patients who have a history of stroke, heart attack, angina and heart failure. By providing continuous monitoring and coordinating the activities of other staff, telemetry nurses can raise the quality of care that your hospital provides to cardiac patients. Telemetry nurses also help patients better understand their heart conditions and fully explain doctors’ instructions to increase compliance and improve overall medical outcomes. During medical crises, prompt care delivered by telemetry nurses can lower the likelihood of fatality.
