Electrocardiographic findings in a partly urbanised Polynesian population. The Funafuti survey.

Electrocardiographic changes defined as probable or suspect ischaemic heart disease and coded according to the Minnesota coding system, were found in 14 (10.3 percent) of 136 Funafutians surveyed. Of these abnormal electrocardiograms, nine were classified as "probable" ischaemia and five as "suspect" ischaemia. There was a higher prevalence of electrocardiographic ischaemia in the female population compared with the male population of Funafuti. This is consistent with the greater degree of obesity and higher prevalence of diabetes previously reported in females in this population.
