Paroxysmal Tachycardia, Epilepsy, Fragilitas Ossium and Mental Retardation

Recently, Derman et al. (1968) reported their studies on electroencephaloSraphic abnormalities in patients with paroxysmal tachycardia and their ifatment with anti-epileptic drugs. They included in their report similar servations made by other workers (Subbotnik et al. 1955, Ringel and Kali^0v, 1964 and Pasini et al. 1967). Their work shows that patients suffering ?m paroxysmal tachycardia, without cardiac pathology, have abnormal uf?tr0encephalogram recordings, especially in the temporal regions, denoting allying malfunction in those areas of the brain. They treated this anomaly
