The hyperventilation syndrome. A pilot study on the effectiveness of treatment

The aim of the study was to discover the relative effectiveness of four methods of treating patients suffering from hyperventilation attacks. The methods used were: breathing and relaxation therapy, hyperventilation provocation training, treatment based on influencing the factors which lead to the development of the syndrome, and drug treatment. The first three methods were demonstrated to be effective, whilst the fourth showed no signs of effectiveness. The condition of patients in the control group remained the same or deteriorated.
