Abstract: The present invention relates to a method for analysing an intracardiac electrocardiogram to identify at least one of the A wave, V wave and H wave on at least one of the electrogram signals, comprising the steps of pre-processing the electrogram signal; calculating an adaptive threshold for the A, V or H wave, wherein the adaptive threshold depends on the noise level of the electrogram signal and on the type of wave; and identifying the A, V or H wave by searching the electrogram signal within a time window determined e.g. from the position of another wave on the same or another electrogram signal.

Abstract: The invention concerns a method for accessing information from a network data source, where the network data source is managed by a server means. In the method an information request is sent through the network to the server means from a requesting telecommunication means, and information is retrieved from the data source with the server means. The information retrieved from the data source is forwarded to a receiving telecommunication means, and further the information used at the receiving telecommunication means is transformed. According to the invention, dynamically determined unique transformation data is associated to the information request, where the transformation data is determined based upon a predetermined and/or previously fixed parameter system. The requested information is transformed based on the unique transformation data, and the information transformed according to the unique transformation data is used at the receiving telecommunication means.
