MEASUREMENT APPARATUS FOR HEART RATE VARIABILITY
First Claim
1. A measurement apparatus for heart rat variability, comprising:
- an earpiece, placed into an ear of a person under test;
a measurement module for photoplethysmographic (PPG) signal, set on one side of the earpiece, measuring the physiological status of the person under test via the ear, and producing a first physiological signal;
a processing module for PPG signal, transmitting a sound signal to the earpiece, receiving the first physiological signal, and producing a first measured signal according to the first physiological signal;
a measurement module for electrocardiographic (ECG) signal, measuring the physiological status of the person under test, and producing a second physiological signal;
a processing module for ECG signal, receiving the second physiological signal, and producing a second measured signal according to the second physiological signal; and
a control and processing unit, transmitting a sound signal, receiving the first measured signal and the second measured signal, and producing a corresponding first waveform diagram and a corresponding second waveform diagram, respectively.

Abstract
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.
