Does heart rate increase with high altitudes
WebFeb 28, 2011 · The lung response to acute altitude exposure is mainly hyperventilation which, together with elevated heart rate, aims at achieving an adequate supply of oxygen to the tissues. At rest, ventilation increases by firstly increasing the tidal volume, at least up to 3500 m. Above this altitude, also the breathing rate significantly increases. WebAcute exposure to high altitude can affect the cardiovascular system by decreasing oxygen in the blood (acute hypoxia). It also increases demand on the heart, adrenaline release …
