Your heart beats 100,000 times every day, pumping about 5 quarts of blood each minute through your body.


According to the Center for Disease Control (CDC), heart disease is still the leading cause of death for both men and women in the United States.  About 610,000 people die of heart disease in the United States every year – that’s one in every four deaths.  Every year about 735,000 Americans have a heart attack.  Of these, 525,000 are a first heart attack and 210,000 happen in people who have already had a heart attack (


Diseases of the heart valves (vascular heart disease or VHD) are a major cause of cardiovascular disease.


Your heart beats about 100,000 times in one day and about 35 million times a year.  During an average lifetime, the human heart will beat more than 2.5 billion times.


Your system of blood vessels, arteries, veins and capillaries is over 100,000 miles long.  That is long enough to go around the world almost four times (The Cleveland Clinic Heart Book 2000). 


Give a tennis ball a good, hard squeeze.  You are using the same amount of force that your heart uses to pump blood out to the body.  Even at rest, the muscles of the heart work twice as hard as the leg muscles of a person sprinting (The Cleveland Clinic Heart Book 2000).


The Heart Sound Recorder (HSR) is a computerized general wellness monitor with a specialized microphone that is placed over each of the four valve areas of the heart.  It digitally records and displays heart sounds and graphs these specific sounds and movements.


The heart’s reaction to stress (i.e., physical, chemical, emotional) can be observed using this device.  Stress on the heart can be monitored by seeing the rate, rhythm and tone of the opening and closing of the valves of the heart (the heart cycle) on the graphs.



RATE, RHYTHM, TONE:  Three key indicators of heart health and function


Your nervous system controls the RATE at which your heart beats.  The rate of your heart is how fast or slow your heart beats.  The optimal resting heart rate is 60-80 beats per minute.  One side of your nervous system (sympathetic) manages your “fight or flight” response and can accelerate your heart rate.    The other side (parasympathetic) manages your “rest and digest” response and can slow your heart rate.  You need a healthy balance between the two.


The RHYTHM of your heart pertains to how regular your heart beats.  There are two heartbeat sounds, “lub” (S1) and “dub” (S2), which should beat in a steady, consistent rhythm.  The rhythm of your heart should show a specific work-to-rest ratio on the graph.  Your heart should be resting twice as long as it is working.  Observations are made to see if your heart is working too hard, or not working hard enough.  Excess stress of various kinds can speed up the heart rate and rhythm.  Other factors can slow the heart rate below normal, as we shall see later in this writing.


The TONE of your heart refers to the strength of the ventricle contractions.












The following graph exhibits TONE, at a faster rate than normal. 

The presence and quality of S2 in any of the valves is highly significant.  There should be 1/3 the height of S1 in all four valves. 









The following graph exhibits RHYTHM.  The indicator for the diastolic rest period should be completely straight.

 If there are signs of flutter, this may suggest a weakness in nerve conduction.










Through nutritional supplementation and lifestyle changes, it is possible for many to improve heart rate, rhythm and/or tone.


Not all stress is bad.  In small amounts, some stresses are necessary, motivating us psychologically and physically, as when we exercise, strengthening the bones and immune system.


It is chronic stress that can be devastating.  Applied over time, this type of stress can cause the body to break down, not allowing the body to return to a place of balance or rest.  Combined with a poor diet or just not getting the proper nutrients, you have a recipe for malnutrition and accelerated breakdown.  Remember, the valves of the heart are made of connective tissue.  They are continually completing their cycle of pumping blood all the time.  The heart is a very specialized muscle.  These tissues require the proper amino acids, vitamins and minerals, etc. to maintain proper functioning.  If the heart does not get the nutrients that it needs for proper functioning, this stress can lead to sub-optimal functioning of the heart and other bodily systems.  The Heart Sound Recorder is really an indicator of how the heart adapts to and recovers from stress.


A person’s ability to adapt to and recover from stress plays a big role in determining whether a person is healthy or not.  The good news is that the body (as well as the heart) is very resilient and can usually, in the majority of cases, respond well with the correction of nutritional deficiencies and malnutrition.


It should be noted that the Heart Sound Recorder is a general wellness cardiac stress monitor.  It is not an electrocardiogram (EKG or ECG).  An electrocardiogram is a test that checks for problems with the electrical activity of the heart, as shown on paper as a line tracing graph.


The Heart Sound Recorder is not in any way a substitution for an electrocardiogram.  The Heart Sound Recorder is classified as a general wellness device by the Food and Drug Administration (FDA).  You understand that if you have or believe that you have a heart condition, you need to be seen by a qualified physician to diagnose and treat that condition.  Furthermore, in an emergency you need to

call 911.

Any suggested nutritional/dietary advice, supplement recommendations or prescriptions are provided to you to support the normal physiological processes of the body.


If you are on any heart medications, you need to stay on them and be monitored by your treating physician.


You fully understand that the Heart Sound Recorder is not an instrument for detecting, preventing or treating heart disease.  Dr. Sklovsky is a naturopathic physician and NOT a cardiologist (heart specialist).  Dr. Sklovsky does not make any claim or guarantees regarding any medical condition or that a patient will get better.


We consider this Heart Sound Recorder to be a wellness, preventative medicine device used to monitor stress and stress patterns as they affect the heart.
