The heart is a muscular organ, which can be described as a bag-shaped pressure device for pumping flesh blood to all parts of the body. Each heart works precisely in a constant period with a circadian rhythm. The heart rate and blood pressure decrease during sleep since the head is placed at the level of the heart. Also, it has been pointed out that other factors in such mechanisms as physical and psychological ones can contribute to changes in the heart rate and blood pressure. Body temperature, blood pressure and the hear rate provide information for the condition of the living body to be examined. Many studies have shown that the heart rate can clearly indicate the stress on the body from excess exercise. At present, the electrocardiogram analysis cannot thoroughly review the condition of the body in all cases. This is due to the fact that the body mechanism is complex. In this paper, authors propose a new method for the analytic evaluation index and a center product rate (M3, M4), with experimental results and discussion on them, in addition to the conventional analytic evaluation index from the electrocardiogram.
