The Boy Whose Anxiety Turned Out To Be His Heart

Hyderabad, 25 August, 2026: A 12-year-old's racing heartbeat had been slowing his childhood for months. A high-density 3D electrical map of his heart finally revealed the rare abnormal circuit behind it — one doctors seldom see at his age. A 12-year-old boy had quietly stopped being himself. His heart would suddenly start racing for no reason, and sometimes he felt dizzy enough to sit down in the middle of whatever he was doing. He had difficulty doing his regular activities for fear of bringing on the symptoms. For months, an active child's world had shrunk — and his parents', turned upside down.

He had earlier been diagnosed with an arrhythmia, an abnormal heart rhythm, and had already undergone a catheter ablation — a procedure that maps the heart's electrical signals through fine wires threaded via a leg vein and blocks the faulty spot in the heart using targeted energy, without any open surgery. But the palpitations kept returning, his heart rate spiking sharply during episodes. Is it just anxiety on the part of the boy, the family wondered? But then another severe episode brought them rushing to the emergency room of Medicover Hospitals at Hitech city. By the time the family reached Medicover Hospitals, they were worried and exhausted, and no closer to an answer.

On assessment, it was clear this was neither plain anxiety nor a routine arrhythmia. The electrophysiology team at Medicover planned a repeat procedure using advanced high-density 3D electrical mapping — a technology that builds a detailed, point-by-point picture of the heart's wiring rather than relying on a handful of reference signals.

Under anaesthesia, recording wires were introduced through the leg veins, and the abnormal rhythm was reproduced in the cath lab so it could be studied directly. The high-density 3D map revealed why the problem had been so persistent despite an earlier procedure: the faulty circuit, sitting in the right upper chamber of the heart, was an uncommon one — the kind rarely encountered in a child this age. In most children, delivering energy at a single critical point is enough. Here, the circuit had to be interrupted at several precise points to shut it down completely. After a procedure lasting over two hours, the abnormal rhythm was terminated. The boy recovered well and went home the next day.

Over the following months, his rhythm medications were gradually withdrawn and he returned to full activity. Nearly a year on, he has remained symptom-free, off medication, and back to sports and school.

Reflecting on the case, Dr. Kumar Narayanan, Senior Consultant Cardiologist & Electrophysiologist at Medicover Hospitals who led the procedure, said: "In children especially, a racing heart or dizziness is often put down to anxiety. Sometimes that's right — but rhythm problems can occur at any age, and when they do, getting the electrical diagnosis exactly right is what changes the outcome. High-density 3D mapping now lets us understand and treat circuits that were once very difficult to reach."

What parents and patients should take from this

 * Heart rhythm problems can affect children too. A child complaining of a racing heart, dizziness or chest discomfort is sometimes brushed off as anxiety or attention-seeking. Sometimes that's right — but it can also be a genuine rhythm disturbance, and rhythm disturbances can occur at any age. It is worth checking rather than assuming.

 * Many rhythm disorders are treatable, even eminently curable, without the need for long-term medicines. Advanced mapping technologies now lets doctors reach and treat circuits that were once very difficult to locate — though every case is different, and outcomes can never be promised in advance.

 * Rhythm disorders are a distinct super-specialty. They are diagnosed and treated by a cardiac electrophysiologist — a cardiologist who, after completing a DM in Cardiology, undergoes further dedicated training in the heart's electrical system, often including international fellowship and board certification. It is an exclusive and small field relative to general cardiology, so if a rhythm problem is suspected, it is worth asking specifically for an electrophysiologist, so the condition is assessed by someone trained for exactly this.
