Advanced Study on the Use of Ivabradine in Supraventricular Tachycardia Caused by Refractory Focal Atrial Tachycardia in Neonates to Avoid Radiofrequency Ablation

July 8, 2021 Disease and Health 0

Supraventricular tachycardia (SVT) is a clinical condition caused by a number of arrhythmias with various etiologies. With an incidence of 1 in 200–250, SVT is the most common arrhythmia in a neonate. The heart rate in SVT is usually greater than 220 beats per minute. SVT can be caused by any arrhythmogenic focus above the ventricles, whether reentrant or isolated ectopic. Tachyarrhythmias and bradyarrhythmias are common. Neonatals tolerated it better than other age groups. SVT shows signs of cardiac failure after at least 36–48 hours. We’re here to tell you about a case of SVT caused by a unifocal atrial ectopic focus that was treated with ivabradine because it didn’t respond to other antiarrhythmic medications. We are reporting this case because there is a paucity of literature on the use of ivabradine in paediatric SVT. Ivabradine should be considered before invasive surgical ablation of the focus, as ablation is associated with additional complications.
