New research pinpoints crucial protein that keeps heart beating on time

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. Now, researchers have helped identify how a particular protein plays a central role in this astonishing consistency. This is the first time the mechanism has been described.
