What is ACG ? ACG (Acoustic Cardiogram) is an innovative medical diagnostic technology, capable of detecting potential problems in Cardio Pulmonary system through advanced acoustic analysis. ACG was researched and developed by Quantum Zen LLP. ACG can detect heart problems such as heart failure, valvular defects, abnormal heart rhythms, congential heart diseases and other structural issues with greater ease and accuracy. It also detects lung issues such as lung failure, blockages, COPD, pneumonia, lung edema and pleural effusion. Also experts can use it to screen certain abdominal issues. ACG is useful as a quick, non invasive diagnostic device to monitor cardio vascular health before moving on to advanced invasive techniques. ACG helps us analyse mechanical function of heart complementing ECG which helps us analyse electrical activity and rhythms of heart. Technology behind ACG: ACG uses advanced acoustic analysis to detect problems in cardio-pulmonary systems. It is superior to traditional stethoscopes and currently used digital stethoscopes in finding subtle anomalies in heart and lung sounds. The sonic vibrations generated by action of heart muscles, valves, blood flow and respiratory sounds from lungs are captured using specialised acoustic transducers and transmitted and stored digitally. This digital acoustic data acts as input to our software core which has advanced spectral analysis features that presents high fidelity audio waves and spectrograms of cardio- pulmonary signals. Coupled with machine learning it helps us identifying structural and functional issues in an effective manner.
