Abstract: Systems and methods for facilitating shared access-right evaluation using linked communication channels are provided. A first communication can be received over a first communication link from a first user device, and a second communication can be received over a second communication link from a second user device. The first and second communications can include requests for the assignment of access rights. Map data can be generated and transmitted to each of the first and second user devices. Each user device can display a visual representation of access-right data. Further, a communication session can be facilitated between the first user device and the second user device. The communication session can be presented on the visual representation for each user device so that the first user and the second user can collaboratively evaluate access rights.

Abstract: Known methods of heart function analysis, while useful, suffer from a number of limitations. These include the fact that these methods are inherently static, in that they consider an individual ECG that can only provide a picture of heart function at a particular moment in time. Furthermore, the assessment depends upon the expertise of specialists performing a visual analysis of ECG traces, which may be subjective, and of limited sensitivity. The present invention provides a method of processing ECG signals. The method comprises the steps of extracting data from at least one ECG signal determining a time derivative of said data and generating a normalised index value representative of the energy in said time derivative. Accordingly, the method provides an index that may be used as an objective indication of heart function, and recorded for an individual patient over a period of time as a dynamic record of any change in heart function of the patient that may be indicative of abnormal function or heart disease.
