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 ...

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 ...

In order for the heart to do its work of pumping oxygen-rich blood to the body, it needs a trigger or electrical impulse to generate a heartbeat. This electrical impulse originates from the sinus node ...

Sinus tachycardia is a heart rate that is faster than normal, and it can be triggered by exercise, stress, or anxiety. However, it may also indicate an underlying health problem. Symptoms of sinus ...

What Is a Normal Sinus Rhythm? Normal sinus rhythm is when your heart beats in a regular, organized way. Your body has a built-in pacemaker called the sinoatrial (SA) node, or sinus node. It uses ...

Low concentrations of three selected biomarkers in the blood of patients with atrial fibrillation identify patients with a high chance of attaining sinus rhythm. This is the main result of this ...

Sinus arrhythmia is the variation in heart rate attributable to respiration. Fox and Forges (1985) have found that the “amplitude” of sinus arrhythmia measured near birth is correlated with ...

Sick sinus syndrome (SSS) is a heart rhythm problem that affects your heart's natural pacemaker. You may develop symptoms of SSS like dizziness, fainting, and fatigue. Treatment may include lifestyle ...

A recent randomized trial in Czechia tested the premise that lifestyle modification and use of antiarrhythmic drugs was as effective as catheter ablation (CA) to treat atrial fibrillation (AF). The ...

A randomized trial that compared previously used and new pacemakers in patients found the reconditioned devices were as safe and effective as new pacemakers, potentially offering affordable options ...
