The heart rate depends on the circulatory system to circulate the blood through the vains and blood vessels. It also depends on the respitory system to breath in oxygen from the lungs, to help the heart pump more blood and give the body a good heart rate pulse... LOL:))
it varies because it depends on how hard you work out.!
electrical impulses
heart rate is controlled by hormones as well as the autonomous nervous system. adrenaline, a hormone increases heart rate while the sympathetic nervous system decreases heart rate. Medulla Oblongata

People who are less active tend to have higher heart rates than more athletic people. Your heart rate is controlled by electrical impulses controlled by the brain. In some folks the "wiring" needs to be adjusted through medication or ablation therapy. Your doctor can order an EKG and tell you if that is the problem or make recommendations to get your heart beat under control.
no the heart rate is controlled by medulla oblagonta
heart rate is controlled by hormones as well as the autonomous nervous system. adrenaline, a hormone increases heart rate while the sympathetic nervous system decreases heart rate. Medulla Oblongata
Heart rate is controlled by the cardiovascular -regulatory systme which is part of the autonomic nerve system.
medulla
By the vagus nerve.

no but your brain does control your heart. also, without a heart your brain cant bunction, and without a brain your heart cant function. hope i helped

In a very active and physically fit person at rest-could be normal though rare. Usually a heart rate of 40 is present in some forms of heart block. Normally, a heart beats at an average of 60-100 beats per minute but this can go lower or higher based on exercise, stress, physical fitness, stress, etc. This heart rate is controlled by a "focus" in your heart, a natural pacemaker (the right atrium). If this fails, your heart does have other options to keep your heart rate going. A heart rate of 40 is usually originating from the ventricles, and is a form of an "escape" rhythm.
