Apparatus, Methods And Computer Programs For Analyzing Heartbeat Signals

A method to be carried out with an apparatus by a user, the method comprising:

• S1—obtaining an audio signal from an audio sensing means wherein the audio signal comprises a subject's heartbeat;
• S2—giving a feedback to the user upon determination that the obtained audio signal has a quality level below a given threshold, and in which case causing step S1 to be repeated
• S3—obtaining a further signal from a further sensing means wherein the further signal also comprises the subject's heartbeat;
• S4—giving a feedback to the user upon determination that the obtained further signal has a quality level below a given threshold, and in which case causing step S3 to be repeated,
• S5—using the further signal to identity individual heart beats in the audio signal;
• and
• S6—analysing the individual heartbeats of the audio signal,
• S7—classifying the individual heartbeats,
• S8—providing a result to the user as to whether the heartbeat of the subject is normal or abnormal.

A computer program comprising computer program instructions that, when executed by processing circuitry, cause:

• obtaining an audio signal from an audio sensing means wherein the audio signal comprises a subject's heartbeat;
• obtaining a further signal from a further sensing means wherein the further signal also comprises the subject's heartbeat;
• using the further signal to identify individual heartbeats in the audio signal;
• and
• analysing the individual heartbeats of the audio signal to enable the audio signal to be classified.
