The Art of The ECG / EKG Machine

Electrocardiogram machines, or ECG and EKG machines, have become some of the most common equipment used to record and measure normal or abnormal action within the heart. The use of EKG machines has become so common due to the wide variety of heart disorders that an ECG machine will detect, along with the ease and speed in which the test is accomplished. Some of the disorders which can be detected by the ECG machine include: valve disease, electrolyte disturbances, prior heart attacks, coronary artery disease, thickening of the heart muscle, and a broad range other possible cardiac problems.

An ECG machine works by recording the electrical action of the muscles in the heart on a graph. Electrodes, usually around 10 of them, are attached to the person on various parts of the body including the arms, legs, and chest. Some machines may have 12-leads of electrodes that attach to the body. The electrodes then sense the electrical action from the heart and send those signals out to the EKG machine to be recorded on a graph. Usually, an ECG machine can perform a test within 5 minutes or less. Physicians are trained to read the graph produced by an ECG machine, and consider the size and length of each individual part of the print out.

In addition, FAA certified commercial pilots must have an electrocardiogram done on a periodic basis with results transmitted to the Federal Aviation Administration. These EKGs must be done on an FAA approved interpretive ECG machine, a list of approved machines can be found here
