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 ...

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 ...

The rhythm is either sinus rhythm or not sinus rhythm. Sinus rhythm refers to the origination of the electrical activity coming from the sinus node — also known as the sinoatrial node ...

In the heart, β-adrenergic receptors are primarily responsible for responding to SNS signals. With a sustained block of the SNS, the researchers observed loss of the day-night rhythm in sinus node ...

Aim: To examine the effects of sinus rhythm (SR) restoration on N-Terminal pro-BNP (NTP-BNP) in patients with atrial fibrillation (AF). Methods: Subjects with paroxysmal and persistent AF and ...

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