Devices, systems and methods of analyzing patient's heart, which are particularly focused on noninvasive techniques of interpreting cardiovascular sounds allow cost-effective and quick diagnosis at the early stages of cardiac dysfunctions. They are equally applicable to adult and pediatric patients. The invention recognizes that effective detection of abnormal cardiovascular sounds and heart lesions can be significantly enhanced by techniques, systems and computer media format that allow to present cardiovascular sounds in time and frequency while keeping signal resolution equally strong in both directions. Invention describes the format and method of constructing it to present the patient's cardiovascular sounds for the detection, identification and prognostication of the heart diseases. A truly unique and novel characteristic of the heart energy signature is its self-referencing feature. Additional benefits include the ability to evaluate heart changes as treatment or disease progresses and to provide unified format for the electronic storage of heart auscultation and cardiac exam findings.
