Conclusion

Heart rate variability has considerable potential to assess the fluctuations in the autonomic nervous system. Here we have examined the impact of meditation – Dialogue with the Body – on heart rate variability. A relaxing effect of meditation on Heart rate variability was observed. Thus this non-invasive methodology is of substantial utility to evaluate autonomic control mechanisms in spite of an incomplete understanding of the physiological significance of HRV parameters.
There was an increase in the RR interval, SDNN and SD2 on day 90 indicating an increase in heart rate variability and relaxation with a decrease in stress. RMSSD and SD1 was found to increas on day 45 indicating stimulation of parasympathetic activity. A decrease …show more content…

    Systolic Blood Pressure Case Study

    Pearce and Nair (2015) agreed that blood pressure is the pressure exerted by blood within the blood vessel. The systolic blood pressure is when the heart contracts and diastolic when the heart relaxes (Timby 2009, p 199). In addition to this, Miller ( 2010, p 4 - 5) states normal systolic blood pressure is 120 mmHg and diastolic 80 mmHg. I placed the cuff above patient's right anti-cubital fossa when I realized I was not supporting her arm; therefore, I made her comfortable by placing a pillow under her arm. Whilst inflating the cuff, the assessor pointed me out I was holding the manometer on my hand; therefore, I rapidly hung it on the upper edge of the cuff where I could see it.…

    The purpose of this experiment is to investigate the heart rate through the dive reflex Homeostasis is the body’s ability to maintain and balance its normal body function in varying conditions. The autonomic nervous system relates to the peripheral nervous system. Its objective is to sustain homeostasis of the visceral organs. In this investigation we will observe the mammalian diving reflex, which implicates the autonomic nervous system. In mammals, immersing the face in water initiates numerous physiological reactions that exploit the time that can be completed under water.…

    Explain The Four Valves In The Heart

    There are four heart valves in the heart. The four main valves in the heart are; the two atrioventricular (AV) valves, the mitral valves (bicuspid valve) and the tricuspid valve, which are between the upper atria and the lower ventricles. The cardiac cycle refers to a complete heartbeat from its generation to the beginning of the next beat, and so includes the diastole, the systole, and the intervening pause. The frequency of the cardiac cycle is described by the heart rate, which is typically expressed as beats per minute.…

    Blood Pressure Analysis Essay

    Methods of analysis: Andrea is a 35 year old female who regularly takes part in cardiovascular exercise. She has recorded her beats per minute (BPM) and blood pressure before, during and after performing exercise with a heart rate monitor and a sphygmomanometer. She completed this experiment during a spin class within a controlled environment and on a fixed spin bike. Findings: BPM Before exercise 96 Average heart rate during exercise 142 Maximum heart rate during exercise 174 1 minute after exercise 98 Blood Pressure Before exercise 119/78 1 minute after exercise 126/76 Evaluation: Before exercise, Andrea’s heart rate was at the high end of a normal heart rate for a healthy adult; between 70 and 100 BPM (British Heart Foundation, 2015).…

    Diastolic Exercise Rate

    al. 210), will remain the same. As noted by Lellamo (2001), one of the many reasons why heart rate increases at maximal intensity is the parasympathetic and sympathetic nervous system. As the nervous system responses to the high power of a certain exercise, nerve signals are sent to the motor cortex of the brain which then send stimuluses to the heart in order for the heart to supply oxygen to the muscles and for the muscles to work at a significant pace. Therefore, the purpose of this lab is to examine the heart rate and blood pressure respond to increasing intensity. It was hypothesized that heart rate and systolic blood pressure would increase with increasing intensity.…

    Cold Water Vasoconstriction

    The heart rate increases immediately after the subject was immersed in cold water. Within 2-3 seconds in cold water we expect to detect tachycardia (Tipton, 1989). During our experiment, our subjects heart rate increased by a huge 35bpm from our basal reading whole body immersion, which was to be expected. This was due to an increase in sympathetic drive, subsequently causing vasoconstriction of the periphery from the release of norepinephrine (Croft et al., 2013; Silverthorn & Michael, 2013). Vasoconstriction of the peripheral following cold water submersion commands the blood to flow to centrally ultimately to ensure the body’s vital organs remain within a homeostatic range.…

    How Does The Mood Of A Dog Affect A Person's Life

    Dogs can directly influence the mood changes that a human can experience throughout their day. The influence that a dog can have on a human’s mood can directly affect their heart rate, as well as other aspects of life. Having an imbalance of mood stability could be a direct indication of the level of stress within somebody’s life. With the increase of stress within someone’s life, that could directly influence his or her heart rate. The sympathetic nervous system is responsible for the fight or flight method that is linked to the rate at which someone’s heartbeats.…

    Biofeedback In Nursing

    Nursing Students experience a significant amount of stress and anxiety during their time in nursing school. In the article Biofeedback Intervention for Stress and Anxiety Among Nursing Students: A Randomized Control Trial, the researchers discuss the use of biofeedback measuring heart rate variability to control the amount of stress and anxiety second year nursing students experience during their clinical. The researchers decided use biofeedback heart rate variability (HRV), since there have been no previous studies on the use of biofeedback devices measuring nursing students stress and anxiety (Ratanasiripong, 2012). In the review of the literature focuses on the previous research on the effects of stress and anxiety in nursing students.…

    Argumentative Essay On Yoga

    Yoga is a repetitive practice of meditation, movement and engaging your breath with your thought. Therefore, it’s moving meditation which engages focus to reduce anxiety and stress. Since stress increases the response of our sympathetic nervous system, it makes it harder for our bodies to alleviate the cause. Garrett Sarley, president and CEO of the Kripalu Center for Yoga & Health in Lenox, Mass., explains that "The muscles tense, the heart beats faster, breathing patterns change, and if the cause of stress isn 't discontinued, the body secretes more hormones that increase blood sugar levels, raising blood pressure. Yoga is one of the few stress-relief tools that has a positive effect on all the body systems involved."…
