摘要:
Method and apparatuses are described to evaluate a state of health of a coronary artery. Vibrational cardiac data from a transducer is received from a first location. The transducer measures vibration of a surface of a humans body non-invasively. The vibrational cardiac data is processed in a second location to create processed vibrational cardiac data. The processing includes separating an unwanted coronary event from the vibrational cardiac data. The processing further includes performing a time-to-frequency transformation on the vibrational cardiac data from a portion of a diastolic interval within a heart cycle to obtain a vibrational frequency power spectrum estimate. The processing includes evaluating a state of health of the coronary artery using the processed vibrational cardiac data.
