title: Parameters of the wave M in 554 patients suspected of tetanic syndrome but with negative ischemic and hyperventilation tests.
abstract: We examined 554 patients with clinical suspicion of tetanic syndrome whose ischemic and hyperventilation tests were negative. We analysed the wave M before carrying out the tests with the following parameters: latency, amplitude, duration, shape and strength of stimulus. We could register higher irritability in women, in young persons, in course of years. We cannot register conspicuous changes during year seasons; the amplitude and the strength of stimulus were in middle correlation. We try to explain the significance of the polyphasic shape of the wave M where the desynchronization and repetitive activity are supposed to be the main causes. The relation between men and women was 1:2.2. Most patients were in the middle age group.
