A Case of Hysteria Showing Spontaneous HyperVentilation Tetany
Russell Fraser, M.B., N.Z., M.R.C.P.Lond., Assistant Medical Officer

ABSTRACT
- Spontaneous hyperventilation tetanic fits are described in a hysterical patient, who had had apparently similar fits during whooping-cough in infancy. A psychogenesis is shown to be closely related to the present illness. Three other illustrative cases are briefly described.
- Observations were made of the biochemical changes during the fits, and of methods of inducing and terminating them. A gaseous alkalosis was found to coincide with the fits, and they could be terminated either by correcting this or by giving calcium intravenously; but calcium, acid or alkali therapy had no definite influence on the tendency to attacks.
- The abnormal susceptibility to hyperventilation tetany, the disturbance of respiratory control seen in these patients and the close intermingling of psychogenesis with physiological abnormalities seen in this patient are discussed; the nature of these latter essential abnormalities is still obscure.
