THE ELECTROPHYSIOLOGICAL DIAGNOSTIC OF TH E T-WAVE RESPONSE

Normal control values for latency and amplitude of T-wave responses we re established using 24 healthy volunteers as controls subjects. Data for masseter, deltoideus, biceps, triceps, adductor, patellar, semiten dinosus, and achilles tendon reflexes were evaluated. T-wave latencies showed small intra- and interindividual differences making them a rep roducible parameter for reflex analysis. T-wave amplitudes did not fol low a Gaussian standard distribution and showed a large interindividua l variation. The amplitudes can be used for intraindividual right-left -evaluation. The applicability of the method is demonstrated in six ca se reports of patients suffering from trigeminal neurinoma, scleroderm a, tetanus, C6 - radicular compression, femoral nerve lesion, and Guil lain-Barre syndrome.
