Chinese Scientists Grow Heart’s ‘Master Conductor’ That Could Replace Pacemaker Chinese researchers have made a groundbreaking discovery in the field of cardiac disease treatment: they have successfully engineered a biological pacemaker using human pluripotent stem cells.
This tiny yet crucial structure, known as the sinoatrial node, acts as the heart's natural pacemaker, sending out electrical signals that control the heartbeat.
The sinoatrial node is often overlooked, but its importance cannot be overstated.
