摘要：The heart is connected through the nervous system directly to major organs and is able to sense their need. The heart also responds to adrenaline in the blood flowing through it. With these inputs the heart is able to adjust its rate to accommodate the needs of the whole body. By its heartbeat, it is able to broadcast a common signal to every cell. One measure of heart health is Heart Rate Variability (HRV). HRV is defined in terms of how different the lengths of time between each heart beat is. The greater the difference in times between heart beats, the healthier is the heart thought to be. Individuals may be able to learn to increase their own HRV and become healthier by a daily meditation practice. This paper uses Heart Variability as the base signal for studying the impact of meditation on it. The paper brings out the difference between pre and post meditation conditions in terms qualitative measure of Power Spectral Density (PSD) variations using Smoothed Pseudo Wigner Ville (SPWVD) distribution method. The simulations highlight the meditation effects overtime period in PSDs
