Pacemaker is one of medical devices implanted in patients' bodies helping their health. It is important to certify accuracy and efficiency of the implanted device in all situations. If the device's software acts improperly, the patient's life will be threatened. As there may be a bug in the medical device's software, software verification is critical. Runtime software verification implies considering requirements of the end users while using the software. In this paper, we present a method to verify the pacemaker behavior. This method considers the fuzzy function of the pacemaker. Using Petri-net (PN) for software verification in addition to simplifying demonstration of the device function is fast and can readily cover concurrent conditions and semi-parallel inference. Moreover, the PN will have a more accurate than inference engine in dealing with unknown values. In this article, we used the Colored Petri-net (CPN) for verification of pacemaker, using MATLAB and CPN tool.
