Atrial tachycardia is one of common tachyarrhythmia,which could present as focal incessant subtype leading to tachycardia-induced cardiomyopathy with poor response to conventional anti arrhythmic drugs.Ivabradine is effective in lowering ventricular response rate or converting and maintaining sinus rhythm for some refractory atrial tachycardia,known as ivabradine-sensitive atrial tachycardia.Nodal-like tissue in ectopic atrial site with the presence of hyperpolarization activated cyclic nucleotidegated cation channel mediated If current leading to increased autoregulation could be the mechanism of ivabradine-sensitive atrial tachycardia.This anticle rewiews the research progress of ivabradine-sensitive atrial tachycardia.
