sinus arrhythmia

This effect is often referred to as normal sinus arrhythmia.

The first, respiratory sinus arrhythmia, is usually found in young and healthy adults.

This is a normal occurrence in healthy individuals and is known as sinus arrhythmia.

This is often accompanied by sinus arrhythmia.

This symptom is usually accompanied by a loss of respiratory sinus arrhythmia - the usual change in heart rate seen with normal breathing.

Demonstrated that early measures of respiratory sinus arrhythmia were related to clinical course in preterm and full term newborns.

It also mediates respiratory sinus arrhythmia.

Introduced respiratory sinus arrhythmia as index of vagal function to the area of psychophysiology.

Respiratory sinus arrhythmia and tympanic membrane compliance predict spontaneous eye gaze behaviors in young children: A pilot study.

Respiratory arrhythmia (or Respiratory sinus arrhythmia).

In one study of canine subjects, ibogaine was observed to increase sinus arrhythmia (the normal change in heart rate during respiration).

Respiratory sinus arrhythmia (RSA) is a naturally occurring variation in heart rate that occurs during a breathing cycle.

The term sinus arrhythmia refers to a normal phenomenon of mild acceleration and slowing of the heart rate that occurs with breathing in and out.

Bainbridge Reflex is involved in Respiratory Sinus Arrhythmia.

Thus, while we do not explicitly measure vagal tone, we do measure changes in heart rate which are a result of respiratory sinus arrhythmia.

During the process of respiratory sinus arrhythmia (RSA), inhalation temporarily suppresses vagal activity, causing an immediate increase in heart rate.

Historically, respiratory sinus arrhythmia was believed to be pathological, and extended bed rest was traditionally prescribed; work by Sir James Mackenzie disproved these ideas.

First to apply measures of respiratory sinus arrhythmia as an index of depth of anesthesia and as a measure of neural function in critical care medicine.

Cardiovascular effects have been recorded with bradycardia and sinus arrhythmia being consistently recorded in 68% of patients treated with mefloquine (in one hospital-based study).

Therefore, we focused on respiratory sinus arrhythmia (RSA) in order to derive statistical information on cardiorespiratory coordination without respiratory flow measurements - see Footnote 2.

Activity in this range is associated with the respiratory sinus arrhythmia (RSA), a vagally mediated modulation of heart rate such that it increases during inspiration and decreases during expiration.

This theory decomposes heart rate variability based on frequency domain characteristics with an emphasis on respiratory sinus arrhythmia and its transmission by a neural pathway that is distinct from other components of HRV.

Since the vagus plays such an integral role in the PNS via regulation of heart rate, it follows that the amplitude of respiratory sinus arrhythmia (RSA) is a good index of PNS activity via the cardiac vagus.
