Abstract
A previously published inverse procedure to calculate the activation sequence at the ventricular heart surface from body surface potentials has been newly implemented and tested. An inability of this procedure to recover endocardial activation times has been detected. This has led to the development of a new inverse method. The new method has been tested in a simulation study and is shown to result in much better estimates of the activation sequence at the heart surface.
