The vital importance of the heart is obvious. if one assumes an average rate of contraction of 75 contractions per minute, a human heart would contract approximately 108,000 times in one day, more than 39 million times in one year, and nearly 3 billion times during a 75year lifespan.
The hearts electrical system. in the simplest terms, the heart is a pump made up of muscle tissue. like all muscle, the heart needs a source of energy and oxygen to function. the hearts pumping action is regulated by an electrical conduction system that coordinates the contraction of the various chambers of the heart. how does the heart beat
Heart rate is a term used to describe the frequency of the cardiac cycle. it is considered one of the four vital signs and is a regulated variable. usually heart rate is calculated as the number of contractions heartbeats of the heart in one minute and expressed as beats per minute bpm. when resting, the adult human heart beats at ...
