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.
