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.

AF, has demonstrated that pulmonary vein isolation (PVI) combined with optimized linear ablation significantly enhances the ...

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 ...

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, ...

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: ...

HeartBeam has submitted a 510(k) application to the US Food and Drug Administration (FDA) for its 12-lead electrocardiogram (ECG) synthesis software tailored to assess various cardiac rhythms and ...

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 ...

Although prolonged auscultation alone would have been sufficient to determine the presence of an arrhythmia (above and beyond the sinus arrhythmia) and would suffice in a clinical setting ...
