Q: I have been diagnosed with high blood pressure. I live at the altitude of 7000 ft. I didn’t have high blood pressure when I lived at sea-level. When I go and visit now my blood pressure is 112/72 or so but my pulse seems to go up in the 70’s. Is this unusual?
A: A pulse of 70 is in the normal range for a resting adult. This rate is not unusual. The climate in lower altitudes is usually warmer and more humid. As a normal response to heat and humidity, the heart pumps faster to keep the body cool. A higher temperature at a lower altitude could cause a faster pulse.
