Abstract
An exemplary method includes detecting a QRS complex using cutaneous electrodes, during the QRS complex, detecting an R-wave of a ventricle using an intracardiac electrode, determining if the R-wave occurred during a first, predetermined percentage of the QRS complex width and, based at least in part on the determining, deciding whether a patient is likely to respond to cardiac resynchronization therapy. Such a method may set the predetermined percentage to approximately 50%. An exemplary model includes a parameter for a percentage for the timing of an EGM R-wave with respect to the total width of an ECG QRS complex. Various other exemplary methods, devices, systems, etc. are also disclosed.
