Genetically engineered cardiac pacemaker: stem cells transfected with HCN2 gene and myocytes - a model [PDF]
arXiv, 2005 Artificial biological pacemakers were developed and tested in canine ventricles. Next steps will require obtaining oscillations sensitive to external regulations, and robust with respect to long term drifts of expression levels of pacemaker currents and gap junctions. We introduce mathematical models intended to be used in parallel with the experiments.
