Report of a patient with refractory atrial tachycardia whose heart rate was controlled using ivabradine
JOURNAL OF INTERNATIONAL MEDICAL RESEARCH(2022)
摘要
Ivabradine is an effective treatment for focal atrial tachycardia. However, it may also be effective for re-entrant atrial arrhythmia. An 85-year-old woman with a history of underlying ischaemic cardiomyopathy complained of worsening symptoms of heart failure because of rapid atrial tachycardia that was resistant to several rate-controlling drugs, but responded well to ivabradine. An electrophysiology study demonstrated a roof-dependent macro-re-entrant tachycardia of the left atrium. Linear ablation of the left atrial roof resulted in termination of the tachycardia. Thus, ivabradine can be an effective treatment for re-entrant atrial tachycardia.
