Abstract
A non-invasive diagnostic tool and method for detecting an obstruction in a coronary artery, the diagnostic tool including a signal processor adapted to receive signals corresponding to a heart beat from a plurality of acoustic sensors attached to the chest of a patient. The signal processor is programmed to identify a diastolic portion of the signals for a plurality of heartbeats and conduct a wavelet transform analysis on the diastolic signals for determining the existence of, as well as the severity and the location of, an obstruction in a coronary artery of the patient.
Claims16
A diagnostic tool for detecting an obstruction in a coronary artery, the diagnostic tool comprising:
- a signal processor adapted to receive signals corresponding to a heart beat from a plurality of acoustic sensors attached to the chest of a patient,
- the signal processor being programmed to, identify a diastolic portion of the signals for a plurality of heartbeats and determine at least one of the severity and the location of an obstruction in a coronary artery relative to a location of at least one of the acoustic sensors.
A method for detecting an obstruction in a coronary artery of a patient, the method comprising the steps of:
- attaching a plurality of acoustic sensors to the chest of a patient;
- receiving a signal from each of the plurality of acoustic sensors, the signals representing a plurality of heartbeats of the patient;
- establishing a threshold amplitude and a frequency range for identifying the signals to be evaluated;
- processing the signals for determining at least one of the severity of an obstruction in a coronary artery and a location of the obstruction relative to the locations of the plurality of acoustic sensors.
