Sinus arrhythmia is a variation in the heart's sinus rhythm, usually caused by changes in a person's breathing cycle. It's a common finding, especially in children and young adults, and its ...

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 ...

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.

Nonetheless, if a person suspects anomalies in the rhythm of their heart rate, they should contact a doctor for a diagnosis. In sinus tachycardia, the heart rate increases but continues to beat ...

One of AI’s most immediate impacts is in screening and identifying patients who may have asymptomatic or paroxysmal AF, those least likely to be diagnosed early but most vulnerable to sudden ...

With a sustained block of the SNS, the researchers observed loss of the day-night rhythm in sinus node pacemaking and in pacemaking ion channels. Surprisingly, the heart’s local circadian clock ...

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 ...

More patients in the PM group were on AADs (PM 40.4%, ABL 4.7%, P < 0.001) while sinus rhythm maintenance was remarkably higher in the ABL group at the end of follow-up (83.7% vs 21.1% in PM group ...

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 ...
