Providence Health Care has established a reputation as one of the leading centres for cardiology research and treatment in Canada. Medtronic of Canada is a major supplier of therapeutic cardiac equipment, technology and implantable devices, and works closely with Providence Healthcare to advance the science of cardiac treatment. Providence Health Care and Medtronic of Canada intend to collaborate on a number of research projects that will potentially further the science and improve patient outcomes in this field. Critical Pathways are standardized, evidence-based schedules of diagnostic tests, medications, and consultations that are implemented to improve the delivery of care to patients with a high risk diagnosis. These pathways have been demonstrated to reduce the variability in practice patterns, improve health care outcomes and enrich health care quality. This project attempts to create and evaluate A Critical Pathway for Cardiac Defibrillators in Patients with Ischemic Cardiomyopathy
