The average heart beats 35 million times a year – 2.5 billion times over a lifetime. Those beats must be precisely calibrated; even a small divergence from the metronomic rhythm can cause sudden death. For decades, scientists have wondered exactly how the heart stays so precisely on rhythm.

This is the first time the mechanism has been described. —> Read More Here
