Researchers at The University of Manchester and Manchester University NHS Foundation Trust have discovered a backup natural pacemaker, which is able to generate a pulse and control the heart rate. The ...

Electric pacemakers can soon be replaced with biologic pacemakers which were developed using sinotrial (SA) node pacemaker cells. These cardiac cells were grown from human embryonic stem cells. A ...

The sinotrial (SA) node is the natural pacemaker of the heart, and is comprised of a group of dedicated heart cells - SA node pacemaker cells - responsible for initiation of the electrical signal ...

Your heart has an internal pacemaker called the sinus node. It's a group of cells, located on top of your heart, that sends electrical signals into the heart and controls your heartbeat. Sometimes, ...
