Quantitative Regular Expressions for Monitoring Cardiac Arrhythmias

摘要

Medical devices offer an ideal test-bed for exploring the applications of formal monitoring methods in system design due to their safety-critical nature that demands predictable operation. In this abstract, we demonstrate the usage of Quantitative Regular Expressions (QREs) for programming Arrhythmia Monitoring Algorithms (AMAs), which are algorithms that continuously monitor the heart rhythm and detect when it is fatal. AMAs run on resource-constrained implantable devices used by millions of patients around the world, like Implantable Cardioverter Debrillators (ICDs) and Insertable Loop Recorders.
