The International Grand Challenge project on Verified Software is a long-term research program involving people from all over the world and is aimed to stimulate the creation of new theories and tools to be applied on industrial-scale problems. One of the challenges proposed is to make a formal development of a cardiac pacemaker. In this paper, we present a formal specification of this system using the Z notation and also discuss our experience in building this formal model and the decisions made during the process.
