PROBLEM TO BE SOLVED: To easily and precisely measure only the R-R interval in the electrocardiogram of a human being at work by placing a vibration measuring means in a position that a movement fixing means, which fixed movements of an examinee, and the chest of the examinee come in contact with each other, and by outputting an obtained signal. SOLUTION: A movement fixing part 2 fixes an examinee 1 in a sitting state, and a vibration measuring part 3 is positioned on a measuring area in the chest of the examinee 1, using a vibration measurement position adjusting part 4. Vibration information that is obtained from the vibration measuring part 3 is sent to external analyzing devices of every kind through a signal transmitting part 5. The analyzing devices of every kind receive a signal from the signal transmitting part 5, perform such a prescribed signal process as amplification and detect an electrocardiograph R wave. The vibration measurement position adjusting part 4 is installed to the movement fixing part 2 as movable. The vibration measuring part 3 is installed to the vibration measurement position adjusting part 4, and movement of the vibration measurement position adjusting part 4 performs positioning of the vibration measuring part 3. |
