The investigators have developed a novel virtual reality (VR) based CR exercise system (MedBike). This system consists of an exercise bike attached to a VR world; it makes exercise engaging and fun. Furthermore, patients can be monitored during exercise remotely over the internet. The investigators intend to perform a pilot randomized controlled trial in which 10 patients are assigned to the MedBike system and 10 to standard CR. The investigators think that the MedBike system will increase exercise program compliance by providing an enjoyable and engaging exercise experience which can be performed in the comfort of one's own home. The investigators think that this will improve fitness (primary endpoint) in these patients. If the investigators demonstrate that home based exercise is feasible, the investigators plan a larger study to prove that it is something that should be broadly implemented in patients with heart disease.
