Every day, your heart beats 100,000 times, sending 2,000 gallons of blood surging through your body. The Heart Sound Recorder is a computer-based, low-risk wellness monitor which uses the principles of auscultation to observe heart sounds. The heart’s reaction to certain stressors, (i.e. chemical, nutritional and emotional), can be observed using this type of device. Certain types of heart stress can be monitored by seeing the rate, rhythm, and tone of the heart cycle on the graph.
