The electrical impulses can be generated spontaneously or can be stimulated. For example electrocardiography records spontaneous electrical impulses generated by the heart during the cardiac cycle. In electromyography the electrical impulses are stimulated by an electrical shock applied to the body. For the caloric study nystagmus is induced by irrigating the ear canal with water. The electrical activity is usually detected by electrodes placed on the body. The electrodes are attached to instruments for receiving and recording electrical impulses. Table 3-1 lists the various areas of the body that can be evaluated by electrodiagnostic studies. PROCEDURAL CARE FOR ELECTRODIAGNOSTIC STUDIES Before Explain the procedureto the patient. Obtain baseline values for comparison during and after the test. 536 Overview 537 TABLE 3-1 Body Areas Evaluated by Electrodiagnostic Studies Name of Test Evaluation Caloric study Cranial nerve VIII Cardiac stress Cardiac muscle Electrocardiography Cardiac muscle and conduction system Electroencephalography Brain Electromyography Neuromuscular system Electroneurography Peripheral nerves Electronystagmography Oculovestibular reflex pathway
