What is Sick Sinus Syndrome (SSS)? Sick sinus syndrome is not a disease condition but a clinical syndrome that is related to the sinoatrial node (SA node). It is also referred to as sinus node disease ...

Minimizing atrial pacing does not alter the risk of atrial fibrillation (AF) associated with sinus node dysfunction (SND), suggest results of a trial that randomly assigned patients with SND who had ...

To the Editor: If Lamas et al. (June 13 issue) 1 wished to compare dual-chamber pacing with single-chamber pacing in patients with sinus-node dysfunction, why did they not compare single-chamber right ...

Dear Dr. Roach: I am an 84-year-old female in relatively good health. My doctor is concerned that my heart rate is too slow, consistently in the 50s. I have worn a Holter monitor and had an ...
