The relationship between the life environment of the atomic bomb survivors (Hibakusha) and their cardiovascular disorders

In order to observe clinically the effects of the atomic bomb on the human body (and on the environment), subjects were divided into group A (persons living in Hiroshima city more than 10 years after dropping of the atomic bomb) and group B (persons who changed their residence within 1 month). Group A was divided into two separate groups: group A1 (persons living in segregated areas), and group A2 (persons living in other areas). General examinations showed no abnormal findings. Incidence of abnormal ECG findings was higher in subjects living in segregated areas and was also higher in women than in men. (Namekawa, K.)
