Summary of Selected Variance Cardiography Studies (.pdf)
The Variance Cardiograph is capable of measuring heart damage at early stages, years before the appearance of other indicators such as high blood pressure, high cholesterol and/or chest pain. Your heart health can be monitored over time with an annual screening plan, from which a profile is generated that can be the basis for an exercise and nutrition program to help prevent heart disease and monitor heart fitness.
The electric current generated by the heart each time it beats is like the flow of a river. As the water encounters obstacles such as logs and rocks the water flow will vary. In a similar manner, as the electric current flows throughout your heart it encounters damaged cells and its path will vary. Variance Cardiography is a technology that accurately detects these variances within your heart and an algorithmic scoring process gives you a basis from which to monitor and even improve on.
More than 15 years of development and Clinical Research Studies have concluded that Variance Cardiography is more accurate than the standard ECG and equal if not more accurate than the exercise stress ECG. The 10-minute resting heart fitness screen is safe, inexpensive and equally effective for both men and women.
The scoring method of HeartFit System called the Heart Variance Index (HVI) has been validated from studies involving subjects who have had an angiogram procedure, which is considered by most health professionals as the gold standard for diagnosing heart disease. Your HVI score will range from 0-150. Lower scores tend to indicate healthy heart cells and higher scores indicate unhealthy cells. The Risk Factor Analysis, which is based on metrics such as total cholesterol, diastolic blood pressure and smoking history, is based on the results of the “Pooling Project”, which collected and analyzed information from over 8000 symptomatic people across a period of 7 years. Combining the HVI and Risk Factor Analysis scores give a comprehensive indication of the likelihood of having heart disease.
