• Attach electrodes to the patients' chests, arms, and legs, connect electrodes to leads from the electrocardiogram (EKG) machine, and operate the EKG machine to obtain a reading.
• Adjust equipment and controls according to physicians' orders or established protocol.
• Check, test, and maintain cardiology equipment, making minor repairs when necessary, to ensure proper operation.
• Supervise and train other cardiology technologists and students.
• Assist physicians in diagnosis and treatment of cardiac and peripheral vascular treatments, for example, assisting with balloon angioplasties to treat blood vessel blockages.
• Operate diagnostic imaging equipment to produce contrast enhanced radiographs of heart and cardiovascular system.
• Inject contrast medium into patients' blood vessels.
• Observe ultrasound display screen and listen to signals to record vascular information such as blood pressure, limb volume changes, oxygen saturation and cerebral circulation.
• Monitor patients' blood pressure and heart rate using electrocardiogram (EKG) equipment during diagnostic and therapeutic procedures to notify the physician if something appears wrong.
• Monitor patients' comfort and safety during tests, alerting physicians to abnormalities or changes in patient responses.
• Explain testing procedures to patient to obtain cooperation and reduce anxiety.
• Prepare reports of diagnostic procedures for interpretation by physician.
• Assess cardiac physiology and calculate valve areas from blood flow velocity measurements.
