Natural Frequencies of Human Hearts - The Practical Way To True Love.
Lateral and Vertical Wave-Propagation Velocities and Natural Resonant Frequencies of Human Hearts
Phuong H. V. Truong
Abstract:
Lateral and vertical wave-propagation velocities and natural frequencies of human hearts by shear wave (S-Wave) and compression wave (P-wave) increase with the increase in the volumes of blood and water in the heart, Poisson’s ratio, Young’s modulus; the volumes of oxygen, nitrogen and other gases; and with the decrease in the mass, thickness and the height of human heart, respectively. Human hearts have been considered as the mixtures of muscle, air and water (MAW) for the analyses. The lateral and vertical natural frequencies of cancerous hearts are found to be extremely low frequencies of 0.7 Hz (8.46%) and 1.5 Hz (8.46 %) compared with those of the normal people, respectively. Lateral and vertical heart-frequency indicators (HFIs) have been introduced in order to importantly stress and easily indicate the healthy level of the heart of each person in lateral and vertical directions, respectively. The higher the positive heart-frequency indicators, the more healthy heart of the person is.
