Summary:398 patients with clinical signs of tetanic syndrome were examined. Their ischemic and/or hyperventilation tests were positive. The parameters of the wave M were analysed i.e. latency, amplitude, duration, shape and strength of stimulus. The signs of higher irritability of the peripheral nervous system were found out in women; they diminished during age. The ratio between men and women was 1:3.6. The significant differences were determined between the groups of negative and positive tests. In the group of positive tests we noticed the dependence of the wave M on the positivity of ischemic, hyperventilation tests, on amount of multiplets during the ischemic test, on the seasons of year and on the course of the period of years (1970-1974 and 1975 to 1978). The highest irritability was determined in the subgroup of hyperventilation tetany and in the subgroup with cramps provoked during ischemic tests.
