The EKG: An electrocardiogram (EKG or ECG) is a test that measures the electrical signals that control the rhythm of a patient's heartbeat. The electrical activity of the heart can be detected through the skin by small metal discs called electrodes. During electrocardiography, the electrodes are attached to the skin on the chest, arms, and legs. The electrodes are also connected to a machine that translates the electrical activity into line tracings on paper. These tracings are often analyzed by the machine and then carefully reviewed by a doctor for abnormalities.
An Electrocardiograph (EKG or ECG) Technician operates equipment which measures and records heart action by monitoring and graphically tracing electrical activity occurring during the heart beat. Physicians use the graphs (electrocardiograms) in diagnosing heart ailments, monitoring heart functions, and recording patients' progress. EKG Technicians are trained on the job, as a rule. Training usually is conducted by an EKG supervisor or a cardiologist and lasts no more than 4 to 6 weeks for the basic "resting" EKG. Training for specialized EKG testing is much more extensive--usually 12 to 24 months--and involves in-depth study of cardiovascular anatomy and physiology. There is currently a high demand for EKG Technicians, if you would like more information about this field can be obtained by contacting: "The National Society of Cardiovascular Technology" (phone # 703-891-0079).
Other, common office "Lab Tests" include Urinalysis (collecting and testing of urine) and Hematology (collecting and testing of a patient's blood). Urine tests involve collecting urine, usually for periods of twenty-four hours at a time. Twenty-four Hour Urine: The doctor or office assistant will give the patient a gallon collection jug, usually with boric acid in it. The instructions are usually printed on the side. Generally, the patient will urinate first thing in the morning, as usual, after that the patient will collect the rest of the urine for the next 24 hours in the jug.
