The heart's normal sinus rhythm is created by electrical signals that spread throughout the heart in an organized manner along a certain route at a particular speed. This article explores sinus ...

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 bradycardia is a slow, regular heart rate. It happens when the sinus node generates a heartbeat fewer than 60 times in a minute. Many people with the condition don’t know they have it.

If there is a P wave before every QRS complex, and it has a sinus morphology, then normal sinus rhythm, or NSR, is said to be present. A sinus morphology is an upright P wave in lead II and ...

Detecting congestive heart failure from inter-beat intervals alone has previously been extremely difficult or virtually ...

size secondary to regular training.6,11–14 A junctional or nodal rhythm occurs when the QRS rate is faster than the resting P wave or sinus rate which is slowed in athletes due to increased vagal tone ...

“This presentation highlights the potential ability of etripamil to successfully convert multiple episodes of Paroxysmal Supraventricular Tachycardia (PSVT) to restore normal sinus rhythm. Further, ...
