Biological Pacemaker Cells Reset Heartbeats

A ‘pacemaker’ composed of natural cells may outperform conventional implanted electronic devices, according to studies by an Israeli-Canadian team

Researchers from Israel and Canada have obtained promising results from an experimental pacemaker made from natural human cells, and believe this system may overcome drawbacks of electrical pacemakers. The team used cells called sinotrial (SA) node pacemaker cells, which make up the natural pacemaker system in the heart.
