Supraventricular tachycardia in children: Clinical features, response to treatment, and long-term follow-up in 217 patients

Catheter ablation of drug resistant supraventricular tachycardia in neonates and infants

“…Supraventricular tachycardia (SVT) is the most common type of tachyarrhythmia seen in pediatric patients, and accounts for more than 90% of pediatric arrhythmias [1]. Symptoms vary according to age, duration of tachycardia and heart rate; neonates and infants can be admitted with congestive heart failure findings [1].…”

“…Symptoms vary according to age, duration of tachycardia and heart rate; neonates and infants can be admitted with congestive heart failure findings [1]. Although SVT in infants can be managed medically in most cases and tends to spontaneously resolve within 1 or 2 years, there is occasionally need for ablative therapy [1][2][3].…”

Surgical management of children and young adults with the Wolff-Parkinson-White syndrome

“…Although the reported incidence of SVT in children is reported to be low (1/25,000), more recent experience suggests a higher frequency [18]. At our institution, 3.5% of patients referred for cardiac evaluation (10,500 patients) have SVT.…”

Reversible Symptomatic Dilated Cardiomyopathy in Older Children and Young Adolescents Due to Primary Non-Sinus Supraventricular Tachyarrhythmias

“…Clinical presentations of non-sinus SVT vary from hydrops and CHF in the newborn [8,20] to episodes of symptomatic tachycardia or CHF and DCM in children, adolescents [4,7], and adults [1,5,13].…”

“…Non-sinus supraventricular tachycardia (SVT), defined as a rapid heart rate for age secondary to an abnormal mechanism originating proximal to the bifurcation of the bundle of His, is the most common symptomatic dysrhythmia in childhood and may present at any age [7,[9][10][11], including the fetus [19,20]. A reversible form of DCM can occur with chronic arrhythmias and is referred to as ''tachycardiomyopathy'' [5].…”
