Abstract (en)
[origin: WO2014153265A1] Methods and apparatuses are described to obtain, cardiac data, which includes acquiring vibrational field cardiac data from a transducer wherein the transducer measures vibration over a surface of a human's body. An unwanted coronary event is separated from vibrational cardiac data. A transient event is extracted from the vibrational cardiac heart cycle data. The transient event occurs during a diastolic interval within a heart cycle. The transient event is evaluated for a condition of coronary artery blood flow turbulence and a condition of health of a coronary artery is assessed from a feature in the vibrational frequency power spectrum estimate.
