title: Circadian heart rate rhythmicity: comparison between an Eskimo and other population groups.
abstract: This brief communication reports the results of 24-ambulatory cardiac monitoring of a Bering Strait Eskimo population and compares the findings with 3 other populations. Similar heart rate rhythmicity and almost identical acrophases are found in the Eskimo, Aymara Indian and French populations. However, the Alaskan Eskimo and Aymara Indian 24-h means vary by approximately 15 beats/min, with the American population between these two. The mesor displays most radical differences.
