I have a heart problem my doctor called sinus node dysfunction. What exactly is this? Contraction of the muscle fibres in the heart is controlled by electricity that flows along distinct pathways ...

sick sinus syndrome (sinus node dysfunction), which can occur as the electrical system of the heart ages; ... The doctor may use an electrocardiogram (EKG) to detect and characterize bradycardia.

However, some forms of sinus node dysfunction have associations with heart disease. Additionally, AFib, which is often present with TBS, increases the risk of stroke. These conditions are treatable.

The ability of an Apple Watch to detect atrial fibrillation (AF) is significantly affected by underlying ECG abnormalities such as sinus node dysfunction, atrioventricular (AV) block, or ...

Minimising atrial pacing does not prevent atrial fibrillation in patients with sinus node dysfunction, according to late breaking research presented in a Hot Line session today at ESC Congress 2023.

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.

It's a type of arrhythmia, meaning the heart rhythm isn't happening in the normal way. Idioventricular rhythm may be seen ...
