Use of ivabradine in supraventricular tachycardia caused by refractory focal atrial tachycardia in neonates to avoid radiofrequency ablation
Supraventricular tachycardia (SVT) is a clinical condition caused by many arrhythmias and from different etiologies. Any arrhythmogenic focus above the ventricles due to reentrant or isolated ectopic focus can cause SVT. Neonates usually tolerate tachy- and bradyarrhythmias better than any other age groups. In SVT, the signs of cardiac failure appear after at least 36–48 hrs. We are here presenting a case report of SVT caused by unifocal atrial ectopic focus and treated by ivabradine as it was not responding to usual antiarrhythmic drugs. Literature showing the usage of ivabradine in SVT in pediatric age group is scarce; therefore, we are reporting this case.
