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 ...

Researchers have identified a gene variant that causes a potentially fatal human heart rhythm disorder called sinus node disease. While the newly discovered gene variant is rare, the study provides ...

DEAR DR. ROACH: At age 76, I was diagnosed with sinus node dysfunction last year after several episodes of what I’d call being “spaced out” (for lack of a better term). I couldn’t explain these ...

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 ...

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 ...

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 ...

Please provide your email address to receive an email when new articles are posted on . Rate-modulated pacing at 60 bpm did not reduce AF incidence vs. nonadaptive pacing at 40 bpm in patients with ...

What Is the Heart Conduction System? The heart conduction system is made up of cells, nodes, and signals that help your heart to beat. In fact, the cardiac conduction system is responsible for our ...
