Changes in the cardiovascular system during acclimatization in the intracontinental region of Antarctica
Observations were carried out at the Soviet Antarctic Station located in the region of the South Geomagnetic Pole. The leading factors affecting the body state were low air temperatures, low atmospheric pressure, prolonged polar night and isolated localization of the winter settlement. During the first six months there were many complaints, including palpitations and pain in the cardiac area. With the appearance of the polar day the number of complaints exhibited a considerable drop. Almost in all the persons observed there were enlargement of the area of cardiac dullness and murmurs. Systolic, diastolic and pulse pressure decreased for the whole period of stay in the Antarctic, especially during the polar night.
The pulse considerably quickened during the first days of the stay, then rapidly dropped to the initial level. Reaction to physical load (pulse acceleration, the rise in arterial pressure, restitution time) was especially marked at first, later less so. A one-year stay is inadequate for complete acclimatization in the Antarctic Continent.
