EKG technicians, sometimes called cardiographic technicians, specialize in electrocardiography, or EKG testing. EKGs measure and record heart action and rhythm by graphically tracing electrical activity occurring during heartbeats. Technicians attach electrodes to the patient’s chest, arms and legs, and then manipulate switches on an EKG machine to obtain a reading. EKG readings are used in diagnosing heart ailments, monitoring heart functions, and recording patients’ progress.
Nationally, the annual salaries (early 2009) of EKG technicians who were employed by hospitals and related institutions were between $24,800 and $31,600, with the average of $27,900, according to the Michigan Jobs & Career Portal. In Michigan, EKG Technicians employed in hospitals and related institutions averaged $29,390 (late 2008), with most earnings between $24,689 and $33,529.
