When resting, the normal average adult human heart beats at about 70 bpm (males) and 75 bpm (females); however, this rate varies among people and can be significantly lower in endurance athletes. The infant/neonatal rate of heartbeat is around 130-150 bpm, the toddler's about 100–130 bpm, the older child's about 90–110 bpm, and the adult's about 80–100 bpm. In your case, your heart must beat 75 times per minute, 4500 beats in an hour, 108,000 beats per day, or about 39,420,000 beats in a year. However, remember that your heart beat will not be constantly the same as the average due to the factor it changes accordingly with your body's activity.IE, sleeping, sitting, walking, running, jumping, hiking, etc. Good Health To You !
