Electrocardiograph technicians use machines to measure electrical activity in the heart to detect heart disease and arrhythmias. They receive formal training and may also administer stress tests. Technicians attach electrodes to patients and provide results to doctors. They can become supervisors or trainers with experience.
An electrocardiograph technician is a medical professional who specializes in administering special types of diagnostic tests for the heart. A technician measures the electrical activity in the heart with electrocardiograph machines and Holter monitors. He or she attaches various electrodes to the patient’s chest and wrists, which are connected to machines or monitors via wires. Heart activity and stress levels are monitored to detect heart disease and arrhythmias. Most electrocardiograph technicians receive formal training through two- or four-year programs at community colleges, schools specializing in medical techniques, or universities.
Electrocardiographs and Holter monitors are diagnostic machines that can detect the electrical activity of the heart in patients at rest. Tests are usually administered to patients who show signs of heart problems or who are about to undergo surgery. EKG procedures are non-invasive and painless, and usually take less than ten minutes to perform. Holter monitors are often worn for about 24 hours to measure long-term changes in heart activity. A technician who specializes in an electrocardiograph may also administer stress tests, in which patients are hooked up to diagnostic machines while participating in activities such as running on a treadmill.
The electrocardiograph technician is responsible for informing the patient of an upcoming test and recording basic vital sign information. He or she attaches electrodes to specific parts of the chest and wrists and turns the machine on. The electrocardiograph or Holter monitor records electrical activity and displays the results on paper printouts or on digital computer screens. Once a test is complete, the technician removes the electrodes, ensures the patient’s vital signs are stable, and provides the doctor with results. Many technicians assist physicians in analyzing findings in order to make accurate diagnoses of heart problems.
To become an electrocardiograph technician in most situations, it is necessary for an individual to complete a two- or four-year training program. Many colleges, universities, and specialty schools offer electrocardiograph courses, which involve both classroom education and actual practice in medical settings. Students receive detailed instruction from experienced medical professionals to learn different terminologies and techniques. In many states and countries, new technicians are required to obtain professional licenses by passing written exams.
Most new technicians learn specific skills on the job helping established professionals. Once they are familiar with the hospital’s policies and equipment, they can begin working independently. With several years of experience, an electrocardiograph technician can become a supervisor, trainer, or administrator. Many experienced professionals teach courses at local colleges or hospital programs to help others learn the trade.
