Key result
AF in rheumatic heart disease is linked to ~50% lower transient outward potassium current density.
Why the study?
Changes in transient outward potassium current (Ito) in right atrial myocytes of patients with atrial fibrillation compared to normal sinus rhythm were not well characterized.
Observational
Answers are grounded in this paper and cite their sources.
Reduced Ito1 density supports AF-related atrial remodeling; leaves open therapeutic targeting pending prospective validation.

孙秀梅 et al. (2002) conducted an observational in Atrial fibrillation in rheumatic heart disease. Atrial fibrillation vs. Normal sinus rhythm was evaluated on Transient outward potassium current (Ito1) density at +60mV (p=<0.001). Atrial fibrillation in rheumatic heart disease was associated with reduced transient outward potassium current density in right atrial myocytes compared to normal sinus rhythm.
