Why the Heart Sound Recorder?

The Heart Sound Recorder was developed in 1937 by Dr. Royal Lee, founder of Standard Process Nutritional Products. Drawing from this background, Dr. Royal Lee, a dentist by education and an inventor by profession, fully realized the significance of the heart as a diagnostic indicator. In 1937, he designed and introduced the Endocardiograph, an earlier version of the Heart Sound Recorder. This “tool” allowed the heart sounds to be graphed. An accurate and detailed recording of the heart sounds was now available for evaluation.

These extremely accurate signature graphs of the HSR provide us with the following information:

  • whether your heart function is optimal or less than optimal
  • if your body’s chemistry is balanced
  • if your body’s nutritional deficiencies are causing stress on your heart
  • what specific nutritional support your body is requiring

In contrast, the electrocardiograph (EKG) records only the surface electrical impulses as it moves through the nerves of the heart tissue.  The EKG primarily indicates if the heart tissue (or nervous tissue network) has undergone any trauma or permanent damage on an electrical basis.  It will not discriminate valvular function, muscle efficiency, etc. The EKG’s sole purpose is to diagnose disease. In contrast, the HSR looks at your heart function as a window to health and longevity.

The HSR takes a picture of heart sounds and enables the practitioner to “hear” by “seeing” heart function on the graph.  We can measure the heart sound as a reflection of balanced body chemistry, nutrition, and overall function of the body’s systems.

In other words, the graph signature is affected by many of our systems, i.e., circulatory, adrenal, liver & gallbladder, kidney function, etc.  Heart function is also affected by vitamins, minerals, essential fatty acids, environmental & food allergies, etc.

The graph for each system’s dysfunction and nutritional deficiency has a characteristic signature.  By using this extremely accurate tool, the HSR, we can easily detect such dysfunctions and deficiencies, thereby helping you make appropriate changes and monitor your progress throughout care.
It is important to emphasize that the HSR reflects the efficiency and deficiencies of heart function.  Through the use of the HSR, the practitioner is now able to fully realize the promotion of health and wellness.

Nutritional Efficiency of the Heart

Your heart is the most important muscle in the body.

Every day it beats 100,000 times, sending 2,000 gallons of blood through 60,000 miles of blood vessels.

It is the first muscle that responds to nutrition.

To function optimally, it is vital that the heart have the proper nutrients to maintain its correct rate, rhythm, and tone. The HEART SOUND RECORDER is a general wellness cardiac stress monitor with a specialized microphone that is placed over each of the four valve areas of the heart to graph specific sounds and movement (as described below).

RATE The “Autonomic Nervous System” controls the rate at which the heart beats. Some bodily functions are directed by the autonomic nervous system such as digestion, heart rate, and blood pressure. These are influenced by diet, vitamins, minerals, and other factors.

RHYTHM This is the “lub dub” sounds of the heart, which should have a specific work to rest ratio. The rhythm can be supported with nutrition that will help balance a heart that is working too long or not resting long enough. Although everyone’s work to rest ratio varies, there are certain guidelines that they should fall within.

TONE This includes the opening and closing of the heart chambers. On the HSR graph, the tone of the heart can be observed by the height and the width of the two sounds made by the heart’s ‘lub dub’ sound.

What you can learn about your heart from the Heart Sound Recorder:

  • Heart Rate – Is it too fast, too slow, or, just right?
  • Heart Rhythm – Is it consistently steady?
  • Heart Tone – Is it STRONG enough with no signs of weakness?
  • Autonomic Nervous System Balance – Are you “riding the brakes” or “hitting the gas pedal”?
