Respiratory 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. Although RSA has been used as an index of cardiac vagal function, it is also a physiologic phenomenon ...
ECG features of sinus arrhythmia. Sinus rhythm with beat-to-beat variation in the P-P interval producing an irregular ventricular rate.
Sinus arrhythmia is detected on the ECGby variations in the PP intervals (often defined as greater than 10% of the mean heart rate but a range of 8–20% has been applied in some studies) with or without variation in the PR interval and is frequently associated with awandering pacemaker. ...
The action potential responsible for this rhythm arises from the sinus node and causes a P wave on the surface ECG that is normal in terms of both amplitude and vector. The presence of sinus bradycardia in itself does not cause a change in the QRS complex and T wave. The frequency of ...
