New Developments in Biological Pacemaker Research

The results of research at Johns Hoplins in Baltimore were released today and show great promise in creating a biological alternative to implanted pacemakers. Scientists used fibroblasts, which are common connective tissues found throughout the body and combined them with regular heart muscle cells to create cells that generate electrical current. When implanted in guinea pigs with artificially slow hearts, their heart rate was quadrupled.
