Excerpt from The Psychoneurotic Factor in the Irritable Heart of Soldiers There is perhaps a certain parallelism between these two groups of irritable heart, and cases of war neuroses. If we understood Dr. Rivers correctly, certain cases of shell shock result in repression neurosis, the anxiety neurosis, while those resulting from exhaustion or infection manifest themselves as exhaustion neurosis (neurasthenia). Similarly in a general way, among patients with irritable heart there are those belonging to the constitutional group, who suffer from chest pain, etc., and those who belong to the exhaustion or the postinfectious group who have fatigue symptoms, but rarely much pain.
