How Specialized Pacemaker Works at Biological Level to Strengthen Failing Hearts: Findings Could Lead to “Pacemaker in a Bottle,” Johns Hopkins University School of Medicine Study

Heart specialists at Johns Hopkins have figured out how a widely used pacemaker for heart failure, which makes both sides of the heart beat together to pump effectively, works at the biological level. Their findings, published in the Sept. 14 issue of Science Translational Medicine, may open the door to drugs or genetic therapies that mimic the effect of the pacemaker and to new ways to use pacemakers for a wider range of heart failure patients.
