20040105556, Jun 3, 2004

Filed:

Nov 18, 2003

Appl. No.:

10/715996

Inventors:

Deborah Grove - North Brunswick NJ, US

International Classification:

A61B007/04

US Classification:

381/067000, 381/058000

Abstract:

A method and apparatus for characterizing the response of an electronic stethoscope. The sensor of the electronic stethoscope is held in contact with a test surface of a phantom. A shaker, which is coupled to a stinger rod that extends inside the phantom, is driven to produce internal vibrations in the phantom. Surface motion of the test surface of the phantom is measured using a surface accelerometer coupled to the test surface. Vibrations from the phantom are detected and an electric signal based on the detected vibrations is generated with the electronic stethoscope. A surface transfer function is calculated based on the measured surface motion and the electric signal to characterize the response of the electronic stethoscope.

Abstract:

A method for assisting in the diagnosis of heart murmurs. The method calculates a normalized measure of mid-range energy for at least one systolic or diastolic interval in a sequence of heartbeats and displays the mid-range energy measure of the systolic and/or diastolic interval in a graphical form. The sequence of heartbeats is also processed to detect and diagnose heart murmurs by adjusting a murmur count threshold responsive to the mid-range energy. The method may be used to diagnose hypertrophic cardiomyopathy and to determine effective therapeutic drug dosage or therapeutic device setting.
