The Cardiac Physiome Project

Cardiac tissue displays a bifurcation in electrical response at rapid pacing rates. Traditionally, this bifurcation has been explained in terms of the slope of the restitution curve, a function that relates the response duration to the duration of the interval preceding it. However, we have recently observed that this curve is not a single-valued function under a wide range of physiological conditions. We will show examples of this restitution curve splitting and discuss the implications.
