Our easy-to-read patient fact sheet compares and contrasts sinus arrhythmia vs AFib (atrial fibrillation) symptoms.

Sinus arrhythmia is a variation in the heart's sinus rhythm, usually caused by changes in a person's breathing cycle. It's a ...

Sinus arrhythmia refers to a changing sinus node rate with the respiratory cycle, on inspiration and expiration. This is quite common in young, healthy individuals and has no clinical significance.

In fact, up to 60% of athletes demonstrate ECG changes (in isolation or in combination) such as sinus bradycardia, sinus arrhythmia, first-degree atrioventricular (AV) block, early repolarisation, ...

Amiodarone effectively maintains sinus rhythm in patients with atrial fibrillation, and although dronedarone is less effective it has a better safety profile. The choice of antiarrhythmic drug (or ...

Sinus rhythm (a.k.a. normal sinus rhythm) refers to the normal heart beat originating from the sinoatrial node. This is manifested as an upright P wave in lead II of the ECG. Sinus bradycardia ...

Objective: To test whether ventilatory thresholds, measured during an exercise test, could be assessed using time varying analysis of respiratory sinus arrhythmia frequency (f RSA). Conclusions: ...

Arrhythmias evaluated include sinus rhythm, atrial fibrillation, atrial flutter, and sinus with premature ventricular contraction (PVC) or premature atrial contraction (PAC). About HeartBeam ...
