The ePace application is primarily developed to monitor parameters collected from implantable cardiac devices that remotely monitor patients. Since vendors use different systems and data storage formats, the application unifies their differences into a single application interface. Implementing the development product into the healthcare system will not only enable online monitoring and early detection of life-threatening conditions in orders of magnitude more monitored subjects, but also the ability to continuously review clinically significant episodes in monitored patients when physical outpatient visits cannot be made. In other words, it is an advanced medical data viewer for pacemaker patients.
