The Mathematics Of A Heart Beat Could Save Lives
What we perceive as the beating of our heart is actually the co-ordinated action of more than a billion muscle cells. Most of the time, only the muscle cells from the larger heart chambers contract and relax. But when the heart needs to work harder it relies on back-up from the atrial muscle cells deep within the smaller chambers (atria) of the heart...
