Heart Sound Recording


The Heart Sound Recorder (HSR) is a computer-based low risk, general wellness monitor which uses principles of auscultation to acquire, display, record and save heart sounds. This can then be used on-going to assess and compare current and previous heart cycle waveforms for before and after analysis and trending purposes.

The Heart Sound Recorder monitors the general wellness of the patient through the characteristics of the sounds of the heart.  A specialized microphone allows the HSR to capture low frequency sounds of the heartbeat.  These sounds of the heart cycle are then displayed as a waveform on a computer. The rate, rhythm, and tone of the heart cycle can be seen.  heart sound recorder

Certain types of heart stress can be monitored when we see the rate, rhythm and tone of the heart cycle displayed in this way. Based on the characteristics of these waveforms, the reaction of the heart to certain stressors can be observed.  Such stressors can be chemical, nutritional and emotional.  


The response of the heart to certain nutrients can be monitored by observing changes of the frequency, ratio, amplitude and characteristics of the heart’s waveform. Comparison graphs of heart stress over time can help determine the effectiveness of treatments used to promote healing and enhance the quality of life.
