Monitoring method and apparatus
First Claim
1. An apparatus for recording a physiological signal from a patient, the apparatus comprising:
- a first part comprisinga first wireless transceiver,a memory for storing a plurality of signal segment templates, an input for receiving an electrical signal, andprocessing means for segmenting a received electrical physiological signal into signal segments, for determining, in a matching operation, whether or not each signal segment matches one of said plurality of signal segment templates that are stored, for storing data including identities and numbers of occurrences of matched templates in said memory together with any signal segments for which a matching template is not found, and for causing said first wireless transceiver to periodically transmit the stored data over a wireless link;
a second part comprisinga second wireless transceiver for receiving data transmitted from said first part over said wireless link,a memory for storing the received data or other data generated using the received data, andprocessing means for generating signal segment templates using said received data, and for causing said second wireless transceiver to transmit to the first part the generated signal segment templates.

Abstract
Apparatus for monitoring an ECG signal comprises a first body wearable part 1 for receiving a physiological signal and comprising processing means, a memory, and a wireless transceiver, the memory storing a plurality of signal segment templates. The processing means is arranged to compare and match segments of the physiological signal to the stored template. The apparatus further comprises a second part 4 comprising a wireless transceiver and processing means, the processing means being arranged to generate and/or modify signal segment templates, and to cause said transceiver of the second part to transmit generated or modified templates to the first part.

13. A method of monitoring a physiological condition, the method comprising:
-
at a first part receiving a signal indicative of said physiological condition; segmenting the signal into successive signal segments; comparing each signal segment against one or more of a set of signal segment templates and identifying matching templates; periodically sending identities and numbers of matching templates together with any signal segments for which a matching template is not found, via a wireless communication link to a second part; at the second part storing received data or data generated from the received data; using said received data, to generate new signal segment templates and transmitting these via said wireless communication link to the first part, and at the first part storing received new signal segment templates for subsequent use. - View Dependent Claims (14)
