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.
