The technician at E.K.G. produces records of electromotive variations in the patient’s heart muscle using an electrocardiograph (ECG) to provide data for the diagnosis of heart disease: places electrodes on the patient’schest, arms, and legs. Connect the electrode cables to the electrocardiograph and start the machine. It moves the electrodes along a specific area of the chest to produce an electrocardiogram that records the electromotive variations that occur in different areas of the heart muscle.
Monitors the electrocardiogram for abnormal patterns. Enter information into the machine or draw marks to indicate the positions of the chest electrodes. Replenishes the paper and ink supply in the machine
