Age | Normal resting heart rate (beats per minute) [1] |

Heart rate (HR) is how many times a heart beats per minute (bpm). The average bpm for a man or women who does not exercise is 70 bpm. Heart rate varies between people because of fitness, age and genetics.
Heart Rate Media
Autonomic Innervation of the Heart – Cardioaccelerator and cardioinhibitory areas are components of the paired cardiac centers located in the medulla oblongata of the brain. They innervate the heart via sympathetic cardiac nerves that increase cardiac activity and vagus (parasympathetic) nerves that slow cardiac activity.
At 21 days after conception, the human heart begins beating at 70 to 80 beats per minute and accelerates linearly for the first month of beating.
