The SigmaPace 1000 External Pacemaker Analyzer is intended for use as regular preventative maintenance and quality assurance checks on external cardiac pacemakers in both the pre-hospital and hospital based environments. The SigmaPace 1000 is limited to preventative maintenance checks for transcutaneous and transvenous types of temporary external cardiac pacemakers. The SigmaPace 1000 will perform a full range of specific testing procedures and protocols developed by the external cardiac pacemaker manufacturers. The SigmaPace 1000 will also provide ECG simulation capabilities for applications in clinical training and product demonstration. The SigmaPace 1000 is intended to be used by biomedical technicians, OEM manufacturers, and third party service facilities to perform preventative maintenance and quality assurance checks on external cardiac pacemakers, to verify the operation of devices returned from repair, and to assist repair facilities in the diagnosis of intermittent performance problems. The SigmaPace 1000 is also intended to be used by training facilities to train medical personnel. The SigmaPace 1000 is not used on patients and does not perform any diagnostic, therapeutic, or monitoring functions. Additionally, these devices are not used to test any programmable, implantable pacemakers or any related indwelling cardiovascular catheters or lead wires.

The SigmaPace 1000 is a device used to verify the performance of various parameters of external cardiac pacemakers. This is done by connecting the external leads of the pacemaker to test inputs on the SigmaPace 1000 and selecting the pacemaker to test or by using the press buttons on the front panel display or via appropriate test cables by serial port (RS232). The SigmaPace 1000 can perform a variety of Transcutaneous and Transvenous (Atrial and Ventricular) Pacer tests. Pulse current, rate, width, and energy Qualitative demand and async mode tests Amplitude sensitivity tests Noise immunity tests Paced and Sensed Refractory tests Selectable model specific transcutaneous algorithms Selectable test loads DC leakage current (tranvenous) Current drain test (transvenous) Long term test for pacer output stability ECG simulation for training activities
