Estimating the term…
The invention relates to a method and an apparatus for identifying a heartbeat. In the method, an arterial pressure signal is measured in the form of multichannel measurement, and the required signal-processing operations, such as filtration, are carried out if necessary. The method also comprises carrying out signal detection and decision-making concerning the acceptance as a heartbeat signal. According to the invention, the signal detection includes multichannel channel-specific detection for the purpose of identifying signal components of different channels, and the obtained channel-specific detected channel signals are used as input data during the decision-making stage.
A method for identifying a heartbeat, the method comprising
An apparatus for identifying a heartbeat, the apparatus comprising a multichannel sensor (2, 21-28), optionally signal-processing means (3, 3a, 3b) for processing a signal obtained from the multichannel sensor, detection means (4) for detecting a signal, and decision-making means (5) for identifying a signal as a heartbeat signal, characterized in that the detection means (4) are arranged to carry out multichannel channel-specific detection on several different channels (C1-C8), and that the decision-making means (5) are connected to perform identification of a heartbeat signal from among said several channel signals detected specifically for each channel.
