Cardiac arrhythmias in children include abnormal heart rhythms originating in the atria, the atrioventricular (AV) node, or the ventricles. The most common paediatric arrhythmias are supraventricular tachycardia (SVT), including Wolff-Parkinson-White (WPW) syndrome, congenital complete heart block, and ventricular tachycardia.

SVT is the most common significant arrhythmia in children, presenting with sudden-onset rapid heart rate (200–280 bpm), pallor, and in infants, poor feeding. WPW syndrome occurs when an accessory pathway connecting atria and ventricles causes pre-excitation and SVT. Congenital heart block (maternal anti-Ro antibody or structurally related) causes slow heart rate, heart failure, and may require permanent pacing.

India's paediatric electrophysiology units at Apollo Chennai, AIIMS Delhi, and Fortis Hospital Bangalore perform catheter ablation for SVT/WPW with high success rates.

Types of Paediatric Arrhythmias

Supraventricular tachycardia (SVT): rapid heart rate originating above the ventricles. Most commonly AVNRT (AV nodal re-entrant tachycardia) or AVRT (AV re-entrant tachycardia via accessory pathway). Presents as paroxysmal rapid heart rate, usually self-terminating or terminable with vagal manoeuvres or adenosine.

Wolff-Parkinson-White (WPW) syndrome: an accessory electrical pathway between atria and ventricles causes pre-excitation (delta wave on ECG) and paroxysmal SVT. Risk of rapid conduction of atrial fibrillation through the accessory pathway causing ventricular fibrillation (sudden cardiac death risk in high-risk WPW).

Congenital complete heart block (CHB): the AV node fails to conduct atrial impulses to the ventricles. Causes bradycardia, heart failure, and syncope. Requires permanent pacemaker implantation.

Who Needs Arrhythmia Treatment?

Children with symptomatic SVT causing haemodynamic compromise, recurrent episodes, or failed medical therapy are candidates for catheter ablation. WPW children with high-risk features (inducible AF with short refractory period on EPS) require ablation regardless of symptoms. Congenital heart block causing symptomatic bradycardia or haemodynamic compromise requires permanent pacemaker implantation regardless of age or weight.

Catheter Ablation for Paediatric Arrhythmias

Catheter ablation is the definitive treatment for SVT and WPW in children old enough (typically >5–10 kg). Under general anaesthesia, diagnostic catheters are placed in the heart via femoral veins. Electrophysiology study (EPS) maps the arrhythmia circuit. Radiofrequency energy or cryotherapy is applied to the arrhythmia substrate (accessory pathway or reentrant circuit) to permanently interrupt it. Success rates for SVT and WPW ablation are 95–98% at experienced centres.

Procedure Steps

1. Non-invasive: 12-lead ECG; 24-hour Holter monitor; exercise test; echocardiogram.
2. EPS: catheters placed via femoral veins under general anaesthesia.
3. 3D electro-anatomical mapping (CARTO or NavX) to identify arrhythmia substrate.
4. Programmed stimulation to induce and characterise arrhythmia.
5. Ablation: RF energy or cryotherapy applied to target substrate.
6. Post-ablation: re-testing confirms non-inducibility of arrhythmia.
7. Recovery: 4–6 hours; discharge next day.
8. Follow-up ECG at 1 month; exercise test at 3 months.

Catheter ablation for SVT in children costs $3,000–$5,500 in India. WPW ablation costs $4,000–$6,500. Pacemaker implantation costs $3,500–$7,500 depending on device type. All are 75–80% cheaper than equivalent procedures in Western countries.

Recovery & Follow-up

Catheter ablation: next-day discharge; return to school or activity within 3–5 days. Pacemaker implantation: 2–3 day hospital stay; restriction from contact sports for 6 weeks. Both procedures have durable long-term success in the vast majority of children.

Recovery Tips

• After ablation, avoid strenuous physical activity for 48 hours.
• Take all post-procedure medications as prescribed.
• Pacemaker patients: avoid strong electromagnetic fields (MRI only with MRI-conditional device).
• Report any recurrence of fast heart rate, palpitations, or syncope.
• Follow-up ECG and exercise test at 3 months to confirm success.

Risks & Complications

Catheter ablation risks: femoral vessel damage (bruising, rare thrombosis), cardiac perforation (<0.5%), AV block (1–2% for septal pathways — may require pacemaker), and radiation exposure from fluoroscopy (minimised by 3D mapping reducing fluoroscopy time). Pacemaker risks: pocket infection, lead dislodgement, phrenic nerve stimulation.

Frequently Asked Questions

At what age can catheter ablation be performed?

Catheter ablation can be performed safely in children from approximately 5 kg (around 3–5 months of age) in experienced hands. For smaller infants, medical management (digoxin, propranolol, flecainide) is typically used until the child reaches an appropriate size for ablation.

Is catheter ablation permanent?

Yes. Successful catheter ablation is a permanent cure for the arrhythmia in 95–98% of patients. A small percentage (3–5%) have arrhythmia recurrence in the first 6 months, requiring a second ablation procedure.

Can SVT cause sudden cardiac death in children?

AVNRT and typical AVRT via accessory pathway rarely cause sudden death. However, WPW syndrome with a short-refractory accessory pathway capable of conducting atrial fibrillation at rapid rates can cause ventricular fibrillation. Risk stratification EPS identifies high-risk patients who require urgent ablation.

Does my child need anti-arrhythmic medication before ablation?

Some children require medication to control arrhythmia frequency until ablation. Flecainide, propranolol, sotalol, and amiodarone are used depending on arrhythmia type and severity. Ablation is the definitive cure and eliminates the need for lifelong medication in most patients.

Can congenital heart block be treated without a pacemaker?

No. Significant congenital complete heart block (causing haemodynamic compromise, syncope, or heart failure) requires permanent pacemaker implantation. Epicardial pacemaker leads are used in very small infants; transvenous leads are placed when the child is larger (>10–15 kg).
