Users often ask us what they could do to get the best results from SensiCardiac. Here are a few tips from our experience:

  • If you can’t hear the heart sound, SensiCardiac can’t either.

Most users violate this rule! Make sure the S1/S2 heart sounds are clearly audible before you start recording.  This is sometimes challenging at the aortic position. Ask the patient to do three to five squats to make the heart work a little bit harder. This may help to hear the heart more clearly.

  • Get the heart as close as possible to the chest wall.

If the patient is in the supine position there’s always the possibility of creating a cavity between the heart and the chest wall. Sounds from within the body, especially the lungs, can resonate within these cavities, creating unwanted noise.

  • Avoid breathing sounds, at all cost.

Ask the patient to hold his/her breath for the duration of the recording.

  • Body tissue is a heart sound killer.

If the patient does have excessive body tissue around the chest/breast and the heart sounds are not audible, don’t use SensiCardiac, or limit the recordings to the positions where the heart sounds are audible.
