ABSTRACT:
Methods, systems, and computer program products can be provided for evaluating a risk of the occurrence of cardiac arrhythmias in a heart. The system can include at least one sensing electrode and a controller. The sensing electrode can be configured to sense electrical signals from a heart over a range of heart rates. The controller can be configured to determine values of a at least one restitution property of the heart from the sensed electrical signals and to evaluate the risk of the occurrence of cardiac arrhythmias from the determine values of the at least one restitution property.
