Evaluating Heart Function and Nutritional Balance
The Acoustic Cardio Graph (ACG) is one of the specialized tools used by Dr. John Erdmann to evaluate the efficiency of the heart and cardiovascular system.
This technology allows us to analyze heart function through sound patterns and graph signatures that reflect how the heart muscle and surrounding systems are working together.
By monitoring these patterns, the ACG can help identify potential imbalances related to cardiovascular function, nutrition, and overall body chemistry.
At Natural Health Family Center, the ACG is often used alongside Applied Kinesiology, nutritional evaluation, and holistic care strategies to help monitor patient progress and guide personalized health recommendations.
The Acoustic Cardio Graph is a diagnostic tool that records and analyzes the sounds and vibrations produced by the heart as blood moves through the chambers and valves. These sounds are translated into graphical patterns that help practitioners evaluate how efficiently the heart and related systems are functioning.
The technology traces back to work first explored by Dr. Royal Lee in the 1930s and has since evolved into a modern tool used in integrative and nutritional health practices.
Rather than being used as a standalone diagnostic device, the ACG is used as part of a broader clinical evaluation to provide insight into cardiovascular performance and overall health balance.

While the ACG does not provide a medical diagnosis, the unique “graph signatures” it produces can suggest patterns that may indicate how the body is functioning.
These patterns may provide insight into:
Examples of areas that may be evaluated include:
These observations help guide a more personalized approach to nutrition and wellness support.
One of the key benefits of the Acoustic Cardio Graph is its ability to monitor changes over time.
By comparing graph patterns from multiple visits, Dr. Erdmann can evaluate how the body responds to nutritional therapies, lifestyle changes, and other holistic treatments.
For example, when a nutritional deficiency is identified, targeted supplementation or dietary changes may improve the graph signature during follow-up testing. This helps provide objective feedback on how well a particular approach is working.

At Natural Health Family Center, the Acoustic Cardio Graph is not used in isolation. Instead, it is integrated into a broader evaluation process designed to support whole-body wellness.
This may include:
By evaluating multiple aspects of health, we can develop a more complete understanding of how the body is functioning.
Got Questions? We’re Here with the Answers.
An Acoustic Cardio Graph measures and records the sounds and vibrations of the heart as it pumps blood through the chambers and valves. These patterns can provide insight into heart function and overall physiological balance.
No. The Acoustic Cardio Graph is not used as a standalone diagnostic test. It is used as part of a broader clinical evaluation to observe patterns that may relate to cardiovascular efficiency and nutritional balance.
The heart is one of the body’s most active muscles and is influenced by factors such as oxygen delivery, electrolyte balance, and nutrient availability. Changes in these areas can affect the way the heart performs.
No. The ACG is a non-invasive evaluation that simply records heart sounds and translates them into graphical patterns for analysis.
By identifying patterns related to nutritional imbalances or physiological stress, the ACG can help guide nutritional support, lifestyle recommendations, and other holistic treatments.
Understanding how your body functions at a deeper level can provide valuable insight into your health and wellness.
The Acoustic Cardio Graph helps provide a unique look at cardiovascular performance and can be used alongside other evaluations to guide personalized care.
