Proving already to be a very resourceful organization, Canadian Pacific began an intense campaign to bring immigrants to Canada.
Return of systemic blood to the heart is impeded by the pressure inside the chest. The output of the heart is reduced and stroke volume falls. This occurs from 5 to about 14 seconds in the illustration. The fall in stroke volume reflexively causes blood vessels to constrict with some rise in pressure (15 to 20 seconds).
Since your bloodstream is responsible for bringing the oxygen to your muscles, your heart needs to pump a great amount of blood for maintaining the oxygen supply to the muscles that are working. To fulfill this goal, the heart starts beating rapidly and forcefully, which increases the heartbeat. In addition to that, if you are exercising on a hot day, then too, the high temperature coupled with the vigorous activity performed by your heart will result in an abnormal increase in your heart rate.
