Abstract

The principles by which "emergent properties" and functional order of self-organizing system, such as the heart, achieve homeodynamic stability provide a non-reductionist framework for understanding how biological systems adapt to imposed internal and external stresses, i.e., ischemia, organ/tissue replacement. Thus, the newly emergent dynamics of cardiac rhythm arising after heart transplantation may represent a more stable, versatile and adaptive regulatory order.
