ELECTROCARDIOGRAM

evaluating an individual’s frequency thresholds, hearing deficiencies can be detected. To test an individual’s frequency thresholds, the technician will use an instrument called an audiometer (manual or computerized). Audiometers used by the Navy are calibrated to American National Standards Institute (ANSI) specifications. Upon entry into the service, a baseline audiogram is performed and recorded on a DD 2215. Subsequent audiometric test results are recorded on a DD 2216 and performed as directed by OPNAVINST 5100.19 and the MANMED. Audiometric testing shall be performed only by personnel who have attended an audiometric training course and have been certified. All audiometric tracings or readings recorded on the SF 88 or other medical documentation should contain the certification number of the person performing the audiometric test. ELECTROCARDIOGRAM An electrocardiogram is a record of electrical impulses made by the heart. Electrocardiograms are produced by an instrument called an electrocardio- graph. The electrocardiograph is used to examine and record electrical impulses produced by the contraction of the heart muscle. Abbreviated either EKG or ECG, the electrocardiogram is interpreted by a physician or cardiologist to determine the heart rate and rhythm, and evidence of any heart damage, especially damage associated with a heart attack. EKGs are currently performed as part of the physical examination once the member reaches the age of 40, and routinely thereafter. Otherwise, EKGs are performed only as clinically indicated or required for special duty. Refer to BUMED instructions for current periodicity information on EKG testing. The Naval Medical Department routinely uses EKGs with 12 leads for physical examinations performed on Navy and Marine Corps personnel. SUMMARY A general review has been provided to you on various types of physical examinations, their requirements, and the documentation procedures of commonly used physical examination forms. We have also discussed physical examination testing equipment and procedures that evaluate vision, hearing, and cardiac function. The physical examination is a key component of the Navy Medical Department’s efforts to maintain the health of Sailors and Marines during times of war and peace. The importance of the physical examination cannot be overstated. The combination of medical history, medical testing, and medical examination furnishes the healthcare provider with a complete picture of the individual’s health. Any indications of medical problems can be evaluated and managed more expediently and effectively through the use of the physical examination. Your assistance with medical testing and your detailed document management will ensure the patient receives the best possible medical evaluation by the medical examiner.
