Sinus rhythm is the term for the regular pattern of heartbeats driven by the heart’s natural pacemaker, the sinus node. Variations like sinus tachycardia (fast heart rate) and sinus bradycardia (slow ...

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 occurs ...

Tachycardia describes when the heart beats faster than normal. Sinus rhythm with tachycardia occurs when the sinus node fires electrical impulses abnormally quickly. Inappropriate sinus tachycardia ...

The diagnosis is normal sinus rhythm, interpolated premature ventricular complexes (PVCs) in a trigeminal pattern, retrograde concealed conduction, intraventricular conduction delay, and old inferior ...

A sinus arrhythmia refers to a problem with the sinus node of the heart. This controls the rhythm of the heart and can be fast (sinus tachycardia) or slow (sinus bradycardia). This article looks at ...

An artificial intelligence (AI) model may identify patients with intermittent atrial fibrillation (AF), even when performed during normal sinus rhythm, in a little as 10 seconds, a new study suggests.
