Abstract
The present invention relates to a system and a method for deriving a high level of information from an Electrocardiogram (ECG) and the use of this method and system. The purpose of the invention is to obtain at least one synthesized lead to give a better representation of any ECG segment than provided by any single physically obtained or derived lead. A further purpose of the invention is to find the one vector-projection for each obtaining of all possible vector-projections containing the largest possible amount of information about the ST-T segment. This can be achieved if the plurality of signals obtained from the body are mathematically expressed into calculation means as multi-dimensional ECG representations where the system performs a transformation of the multi-dimensional signals in relation to an optimal orientation of at least one projection vector regarding relevant information of a predefined segment of the signal into at least one synthesized ECG representation. The derived ECG representation can be used for diagnosis of congenital Long QT Syndrome or in drug testing for acquired Long QT Syndrome.
