When this variability is more accentuated, the term sinus arrhythmia is used The most common cause of shortterm sinus arrhythmia is respiration Respiratory sinus arrhythmia (RSA) is a normal finding and may be quite marked (up to 10 to beats/min or more), particularly in children and young adultsDec 25, 11 · Multiple heart period oscillations were observed to occur during breathing cycles Both respiratory and nonrespiratory sinus arrhythmia was observed amongst healthy adults This observation at least partly explains why heart period parameters and heart rate variability parameters are not reliable estimators of breathing frequencyKeywords blood volume pulse, heart rate variability, respiratory sinus arrhythmia, cardiorespiratory synchrony Biofeedback Volume 35, Issue 2, pp 5461 Table Alphabet soup of abbreviations BVA Blood volume amplitude BVP Blood volume pulse CRS Cardiorespiratory synchrony EKG Electrocardiography ECG Electrocardiography FFT Fast Fourier transform Q Tbn And9gcsii
