    pulse rate = heart beats per minute
    heart beats to get oxygen round body
    if less oxygen = higher pulse
    haemoglobin has affinity for CO > Oxygen so smokers have significantly higher resting pulse rate


    i think thats relevant?

    If a person is a smoker then there are many ways the pulse rate may be affected. The smoke may cause the cholesterol in arteries to break off and partially clot the vessel. This increases blood pressure. The carcinogens too have a bad effect on the heart increasing heart rate.

    Again if the person drinks alcohol, then this too increases the heart rate.
