Abstract
A method and apparatus are provided for determining the compatibility between a selected implantable pacer and a patient within which the pacer is to be implanted wherein the pacer does not have to be directly connected to the patient during the compatibility check.Actual cardiac signals from the patient are digitized and a storage frame is established about a complete cardiac waveform. This cardiac waveform can be reproduced in analog form for presentation to the pacer. Further, the amplitude of the reproduced cardiac waveform may be varied in a manner determined by an active search routine wherein the threshold response of the cardiac pacer can be determined. In a preferred embodiment, the threshold response determination is also used to provide an output signal indicative of the degree of compatibility between the selected cardiac pacer and the actual patient selected to receive the pacer.
