What Is Inspiration And Expiration In The Respiratory System?

WebChanges in lung volume can produce changes in heart rate by activation of afferent signals by the lung and reduction of vagal tone. These increase heart rate during inspiration and slow the heart rate during expiration in what is called sinus arrhythmia. This pattern is more common in young individuals. WebRespiratory sinus arrhythmia (RSA) is heart rate variability in synchrony with respiration, by which the R-R interval on an ECG is shortened during inspiration and prolonged during expiration.
