The present study was designed to evaluate the psychosocial status and the mental health of children receiving a permanent pacemaker during childhood. Nineteen children under the age of 19 years had a permanent pacemaker implanted. Contact was established to 15 of these patients, 7 girls and 8 boys, and they were given a child-psychiatric evaluation consisting of a semi-structured and a child-psychiatric interview. The psychological interview used intelligence tests and the Draw-A-Person test as well as the Rorschach test. The patients had had their pacemakers during an average of 6.7 years (range 3-14). Generally the psychological condition was strained in 7 families, in which psychiatric and social therapy had been necessary. The children's intelligence was within normal ranges, average IQ being 110 (range 80-135). The children had abnormal body image related to the pacemaker. Adults virtually incorporate the pacemaker in their body image without disturbance, but children who are forming their body image and identity, are influenced by having a pacemaker. This may give psychosocial implication.
