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 ...

Bradycardia is a slow heart rate, defined as a heart rate of less than 60 beats per minute. Bradycardia can be caused by a range of factors, including diseases such as: sick sinus syndrome – a number ...

Sick sinus syndrome (SSS) is the name that doctors use to refer to heart rhythm problems. These occur when the sinus node, the heart’s natural pacemaker, does not keep a regular heartbeat. This heart ...

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 ...

Abnormal heart rhythms (dysrhythmias) are caused by disturbances in electrical impulse generation or by abnormal conduction between chambers of the heart – principally within the sinus node, ...

AMSTERDAM -- Reducing atrial pacing didn't help prevent atrial fibrillation (Afib, or AF) in patients with sinus node dysfunction but did increase risk of fainting, the DANPACE II trial showed. The ...

The identification of nearly a dozen ion channel genes involved in the genesis of human atrial and ventricular arrhythmias has been critical for the diagnosis and treatment of fatal cardiovascular ...

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 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.
