Microgravity alters respiratory sinus arrhythmia and short-term heart rate variability in humans.
We studied heart rate (HR), heart rate variability (HRV), and respiratory sinus arrhythmia (RSA) in four male subjects before, during, and after 16 days of spaceflight. The electrocardiogram and respiration were recorded during two periods of 4 min controlled breathing at 7.5 and 15 breaths/min in standing and supine postures on the ground and in microgravity. Low (LF)- and high (HF)-frequency ...
متن کاملIs There More to Blood Volume Pulse Than Heart Rate Variability, Respiratory Sinus Arrhythmia, and Cardiorespiratory Synchrony?
A growing body of research reports the health benefi ts of training heart rate variability (HRV), and the clinical use of HRV training protocols has increased dramatically in recent years. Many of the home training devices and many of the sophisticated biofeedback instrumentation systems rely on the blood volume pulse (BVP) sensor, or photoplethysmograph, because it is more user friendly than t...
متن کاملThe effects of respiratory sinus arrhythmia biofeedback on heart rate variability and posttraumatic stress disorder symptoms: a pilot study.
Recent studies have found a significant association between PTSD and low heart rate variability (HRV), a biomarker of autonomic dysregulation. Research indicates that respiratory sinus arrhythmia (RSA) biofeedback increases HRV while reducing related pathological symptoms. This controlled pilot study compared RSA biofeedback to progressive muscle relaxation (PMR) as adjunctive interventions for...
متن کاملRespiratory sinus arrhythmia in humans: how breathing pattern modulates heart rate.
The relationship of respiratory sinus arrhythmia amplitude (RSA) to tidal volume and breathing frequency was quantified during voluntarily controlled tidal volume and breathing frequency and spontaneous quiet breathing. Seventeen seated subjects breathed via mouthpiece and nose-clip, maintaining constant tidal volumes at each of several breathing frequencies. Inspiratory breath hold was zero fr...
متن کاملHeart rate orienting and respiratory sinus arrhythmia development in rats exposed to alcohol or hypoxia.
The effect of alcohol exposure and hypoxia on the heart rate orienting response and RSA development was studied in preweanling rats. Rats were artificially reared from postnatal days 4 through 12 and either exposed to alcohol (5 g/kg/day) or hypoxia (two 15-min episodes/day) from postnatal days 4 to 10. Control groups consisted of artificially reared and normally reared rats not exposed to alco...
