The value of non-invasive cardiac function measurement in physical examination is shown in the following :

Early warning of heart
function decline

For people who are at high risk of cardiovascular diseases, non-invasive cardiac analysis detects early complications and later be reversed through non-drug practices, such as proper exercises, diet change and lifestyle adjustments. Consequently, early cardiac dysfunction can be regulated or better yet, reversed. Other cardiac examinations (e.g. ECG, Echocardiography, Coronary CT, Nuclear Magnetic Resonance, Radionuclide Scanning, etc.) are aimed at organic lesions, that is when the disease has led to clear anatomical and morphological changes, leading to pathological blood perfusion and dysfunction. In that case, these health complications are difficult to reverse and treatments could be costly and problematic.

Counterpart to traditional
low cost heart inspection
ECG

Its main function is to help determine whether the electrical activity of the heart is normal. It is used to diagnose arrhythmia, myocardial ischemia or myocardial infarction, and determine its locations. However, electrocardiograms cannot provide an accurate quantitative measure of cardiac pump function and blood flow measurement.

Echocardiography

Non-invasive examination of the heart and large blood vessels using ultrasound to detect the anatomy of the heart and determine cardiac functions. The technology is only suitable for screening heart diseases patients or high-risk people with specific heart issue symptoms, not for healthy people on preventive or wellness purpose.
