As an ECG technician, your job is to perform an electrocardiogram procedure on patients who visit your clinic, hospital, or specialized medical facility. In this role, you monitor cardiac rhythms, give data to attending physicians, report abnormal results, move and configure testing equipment, and talk to patients during procedures. You also perform maintenance on scanning equipment. Many ECG technicians also respond to medical codes, particularly those calling for urgent tests or interpretation. The ability to remain calm in highly stressful situations is essential to your success in this position. Some employers abbreviate this job as EKG technician instead of ECG technician.
