Absolutely. Once a person has something to fear, their "fight or flight" response kicks in which will increase the heart rate and breathing rate so there is more oxygenated blood going to the muscles and they can fight or run.

∙ 10y agoYes, your heart rate will increase when you get scared. If you get scared enough to get an adrenaline rush ("fight or flight" response), your heart rate goes WAY up to make sure your body has the blood it needs to either fight or run. Being tense in a scary situation can get your heart rate up as well.
