An in-vitro testing system to assist in optimal programming of an ICD is provided which avoids the inconvenience and health risk associated with repetitive inductions of an arrhythmia. The system includes a high speed computer having analog-to-digital and digital-to-analog subsystems. The system includes software which provides real-time capture and storage of a patient's electrogram. Subsequently, the electrogram may be played and replayed into ICD software simulators at a variety of settings to determine candidate programming parameters. The system further includes an attenuator through which signals are fed on their way to an ICD. This arrangement provides a method by which validation of the simulation system may be achieved. The system also provides for the capture of output event markers simultaneously with the signal into a digital file for assessment of device performance. |
