Abstract
A bio signal measuring apparatus. The bio signal measuring apparatus includes an electrocardiogram measuring attached to the skin of a patient to measure an electrocardiogram signal of the patient. A heart sound sensor contacts the skin of the patient to measure a heart sound signal of the patient. A controlling unit obtains bio information including at least a heart rate from the electrocardiogram signal using the heart sound signal.

15. A bio signal measuring method comprising:
-
measuring an electrocardiogram signal and detecting an R peak from the electrocardiogram signal using a first threshold value;
measuring a heart sound signal and determining a window from the heart sound signal;
determining whether the R peak is detected in the window; and
calculating bio information from a plurality of R peaks which were previously detected if the R peak is detected in the window. - View Dependent Claims (16, 17, 18)
