Aconcagua, Argentina. Parameters measured include heart rate, systolic and diastolic blood pressures, cardiac output and stroke volume calculated by Balke's formula, urinary protein, glucose and pH, RBC and Hb of blood, and muscle strength measured by a hand dynamometer and a pinch-meter. Cardiovascular dynamics judged by those parameters was markedly changed during the first two weeks and tended to be normalized towards the end of the third week of sojourn. Diastolic blood pressure continued to increase until the end of the second week. This increase of diastolic blood pressure may be caused by increased peripheral resistance due to increased blood viscosity, and may add extra work load on the subject's heart. Protein was excreted in urine when the cardiac work was lowered during this period. RBC and Hb did not increase until the third day. Subjective symptoms were also checked and analysed.}, pages = {231--237}, title = {Studies on the Adaptation to High Altitudes with Special Reference to Changes in Cardiovascular Functions}, volume = {29}, year = {1967} }
