20100262024HEART RATE VARIABILITY MEASUREMENT METHOD - A heart rate variability measurement method is revealed. The method includes the following steps. At first, play a piece of music for a participant. Then detect a change in vascular volume of the participant. Next depict a continuous waveform signal of the change in vascular volume. Thus while measuring the heart rate as well as heart rate variability, the participant is not easy to get nervous or impatient and the real heart rate as well as heart rate variability can be obtained, without being affected by the mood. Therefore, the accuracy of the heart rate variability during measurement is increased.10-14-2010
20100262025APPARATUS FOR MEASUREMENT OF HEART RATE VARIABILITY - The present invention provides an apparatus for measurement of heart rate variability, comprising a main body of a earphone to be inserted into a patient's ear, a light source disposed on one side of the main body, emitting light projected onto the skin of the patient's ear, and a sensor disposed on the same side of the main body with the light source, receiving a reflection light from the skin of the patient's ear, and accordingly generating and transmitting a sensing signal to an analyzer for measurement of the heart rate variability. Thus, the heart rate variability of the patient can be measured by operation of the light source and the sensor when the patient is listening to the music through the earphone. In this way, true heart rate variability, without being affected by the patient's nervousness or impatience, can be derived.10-14-2010
20100274109MEASUREMENT APPARATUS FOR HEART RATE VARIABILITY - The present invention relates to a measurement apparatus for heart rate variability, which comprises an earpiece, a measurement module for photoplethysmographic (PPG) signal measuring an ear and producing a first physiological signal of a person under test, a measurement module for electrocardiographic (ECG) signal measuring a second physiological signal of the person under test, and a control and processing unit transmitting a sound signal to the earpiece. By playing the sound signal from the earpiece, the attention of the person under test can be detracted from the measurement module for PPG signal or the measurement module for ECG signal. Thereby, nervousness and impatience of the person under test can be eliminated, and hence the real heart rate variability of the person under test can be measured.10-28-2010
