When this system malfunctions, palpitations can occur. https://cdn.cybassets.com/s/files/5993/ckeditor/pictures/content_4a09ff6f-00d0-4091-9a7d-8226be9716b3.JPG A normal resting heart rate averages between 60 to 100 beats per minute. Extrapolating from this rate, a person's heart beats an average of 2.5 to 3 billion times in a lifetime. What's more interesting is that the human heart doesn't start beating only after birth; a fetus's heart begins to beat from the 22nd day in the mother's womb, and by about 4 weeks, it already functions for blood circulation. https://cdn.cybassets.com/s/files/5993/ckeditor/pictures/content_d193bf67-7371-4a58-a61e-ce0a4cd42368.png Convey those heart-fluttering moments and express your most sincere blessings.
