Scientists have revealed the source of human heartbeat in unprecedented detail, an advance that may help surgeons repair hearts without damaging precious tissue.

Researchers, including those from University of Manchester in the UK, developed a way of producing three dimensional (3D) data to show the cardiac conduction system — the special cells that enable our hearts to beat.

"The 3D data makes it much easier to understand the complex relationships between the cardiac conduction system and the rest of the heart," said Jonathan Jarvis from Liverpool John Moores University.

Within the heart, there is a special network called the cardiac conduction system that generates and distributes a wave of electrical activity stimulating the heart muscle to contract, researchers said.

This system makes sure that the various parts of the heart contract regularly and in a coordinated way.
