Relaxation and Heart Rate Variability

02:18 EDT 25th October 2014 | BioPortfolio

Summary

Primary:

- To characterize the physiologic changes of the autonomic nervous system, demonstrated by heart rate variability (HRV) high frequency (HF) spectral analysis, before and after a 15 minute, one-time, guided relaxation program for cancer patients.

Secondary:

- To assess whether change of HRV correlates with subjective feeling for anxiety, based on visual analog scale scores.

Description

Rhythm changes in your heart rate are part of the "autonomic" nervous system. This is the part of your nervous system that controls the body functions that you do not have to think about. Researchers want to find out if a "guided relaxation" session will make your heart rate more variable, with more rhythm changes.

If you are found to be eligible to take part in this study, you will first answer a brief questionnaire that will measure several symptoms, such as pain and anxiety (worry). This questionnaire will take less than 5 minutes. You will also be asked questions about your alcohol and smoking history, and if you have ever used relaxation or meditation techniques in the past. This will also take less than 5 minutes.

You will then be asked to lay on your back, on a hospital bed or exam table. Electrodes will be placed along your chest, the same way they are placed for an electrocardiogram (ECG--a test to measure the electrical activity of the heart). You will be asked to rest for 15 minutes, and then your heart rhythm will be recorded for 5 minutes. After this first recording, you will begin the relaxation program by listening to an audio recording for about 15 minutes, using headphones. After the relaxation program has ended, your heart rhythm will be recorded for another 5-minute period while you are resting.

You will then be asked to complete the same questionnaire as before.

The entire procedure will take about 45-60 minutes. After this second questionnaire, your participation on this study will be over.

This is an investigational study. Up to 20 people will take part in this study. All will be enrolled at M. D. Anderson.

Medical and Biotech [MESH] Definitions

The molecular designing of drugs for specific purposes (such as DNA-binding, enzyme inhibition, anti-cancer efficacy, etc.) based on knowledge of molecular properties such as activity of functional groups, molecular geometry, and electronic structure, and also on information cataloged on analogous molecules. Drug design is generally computer-assisted molecular modeling and does not include pharmacokinetics, dosage analysis, or drug administration analysis.

A cancer registry mandated under the National Cancer Act of 1971 to operate and maintain a population-based cancer reporting system, reporting periodically estimates of cancer incidence and mortality in the United States. The Surveillance, Epidemiology, and End Results (SEER) Program is a continuing project of the National Cancer Institute of the National Institutes of Health. Among its goals, in addition to assembling and reporting cancer statistics, are the monitoring of annual cancer incident trends and the promoting of studies designed to identify factors amenable to cancer control interventions. (From National Cancer Institute, NIH Publication No. 91-3074, October 1990)

A method of chemical analysis based on the detection of characteristic radionuclides following a nuclear bombardment. It is also known as radioactivity analysis. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)

A class of drugs that act by selective inhibition of calcium influx through cell membranes or on the release and binding of calcium in intracellular pools. Since they are inducers of vascular and other smooth muscle relaxation, they are used in the drug therapy of hypertension and cerebrovascular spasms, as myocardial protective agents, and in the relaxation of uterine spasms.

Analysis based on the mathematical function first formulated by Jean-Baptiste-Joseph Fourier in 1807. The function, known as the Fourier transform, describes the sinusoidal pattern of any fluctuating pattern in the physical world in terms of its amplitude and its phase. It has broad applications in biomedicine, e.g., analysis of the x-ray crystallography data pivotal in identifying the double helical nature of DNA and in analysis of other molecules, including viruses, and the modified back-projection algorithm universally used in computerized tomography imaging, etc. (From Segen, The Dictionary of Modern Medicine, 1992)
