Method and portable monitoring module for monitoring a plurality of electrical biosignals of a person

Disclosed is a portable monitoring module and a monitoring method utilizing the module for monitoring a plurality of electrical biosignals of a person. The module includes a measurement for measuring an electrical biosignal from the at least two electrodes, a wireless communication unit, and a processing unit. The processing unit selects a biosignal type to be monitored from a list of types supported by the monitoring module, store samples of biosignal data generated by the measurement unit, detect an indicator pattern within the biosignal data, wherein the indicator pattern represents an indication of a possible event of the selected biosignal type, and send a set of biosignal data wirelessly to a validation system. The set of biosignal data represents a sequence of samples of biosignal data related to the detected indicator pattern, and the validation system confirms the presence of the event in the received set of biosignal data.
