Abstract:
A method performed by an external programmer in combination with an implantable cardiac stimulation device implanted within a patient and a multiple-lead surface electrocardiogram (EKG) unit, the method comprising:inputting separate initial multiple-lead surface EKG signals from the EKG unit detected using separate surface electrodes attached to the patient; inputting initial internal electrical cardiac signals sensed by the implanted device using internal electrodes; generating, based on a comparison of the initial surface EKG signals and the initial internal cardiac signals, a set of conversion values for converting additional internal cardiac signals into separate multiple-lead surface EKG signals; and emulating separate multiple-lead surface EKG signals based on additional internal electrical cardiac signals using the conversion values such that the surface EKG unit is no longer needed.
