1. An apparatus comprising:
- instrumentation that comprises one or more sensors for sensing a time-variant physiological parameter of an individual, and a data processing device configured to perform data processing activities, the activities including identifying events in the sensed physiological parameter, allocating events into categories based on characteristics of the sensed physiological parameter, discarding at least some of the events based on characteristics of the sensed physiological parameter, and associating data describing times when the events that are not discarded occurred with data describing the categories of the events, wherein each event comprises a period of time when an information content of the physiological parameter is of increased medical relevance, and a data output configured to output the associations of the data describing the times and the data describing the categories.

Abstract
Systems and techniques for managing biological signals. In one implementation, a method includes receiving a cardiac biological signal that includes information describing events, determining a merit of each event based on one or more of a severity of a cardiac condition associated with the event and a quality of the event, and handling a subset of the events that meet a merit criterion. The subset can be handled for medical purposes.

sensing, at a patient-portable sensor module, physiological electrical activity of an individual;
identifying a collection of events in the sensed physiological electrical activity, wherein each event comprises a period of time when an information content of the sensed physiological electrical activity is of increased medical relevance;
discarding at least one event based on characteristics of the sensed electrical activity; and
transmitting data describing the events in the collection that are not discarded to a receiver in a vicinity of the patient-portable sensor module. - View Dependent Claims (11, 12, 13, 14)

15. An apparatus comprising:
-
a monitoring instrument that comprises one or more sensing elements for sensing a time-variant physiological parameter of a monitored individual, a data processing device configured to perform data processing activities, the activities including identifying an event in the sensed physiological parameter, determining a severity of the event based on characteristics of the sensed physiological parameter during the event, determining whether the event is sufficiently severe to warrant immediate output, immediately outputting a description of the event if it is determined that the event is sufficiently severe, and storing data describing the event in association with data describing a time when the event occurred if it is determined that the event is not sufficiently severe, and a data output configured to output data, wherein the event comprises a period of time when an information content of the physiological parameter is of increased medical relevance. - View Dependent Claims (16, 17)

18. A system comprising:
-
a collection of electrocardiographic monitoring instruments that each comprise a collection of electrodes for sensing electrical activity of a heart of a monitored individual, a data processing device configured to perform data processing activities, the activities including identifying an event in the sensed electrical activity, classifying the event into a category based on characteristics of the sensed electrical activity, and associating data identifying the monitored individual and data describing the category of the event, and a wireless signal output configured to output the association of the data identifying the monitored individual and the data describing the category of the event; and
a receiver that comprises a wireless input configured to receive the associations output from each of the electrocardiographic monitoring instruments, wherein the event comprises a period of time when an information content of the sensed electrical activity is of increased medical relevance. - View Dependent Claims (19, 20, 21, 22, 23)
