Children's ECG & 24-Hour Holter Monitor

Gentle, child-friendly 12-lead ECGs and lightweight ambulatory Holter monitors with consultant paediatric cardiologist Dr Nitha Naqvi at 77 Wimpole Street, Central London.

What is a children's ECG and 24-hour Holter monitor?

A paediatric electrocardiogram (ECG) is a quick, painless test that records the heart's electrical rhythm using small stickers on the chest. A 24-hour Holter monitor is a miniature, lightweight recorder worn under clothing that continuously captures heart rhythm data during everyday school activities, sports, and sleep to detect intermittent palpitations or dizzy spells.

12-Lead Resting ECG

Performed in minutes during your clinic appointment. It measures heart rate, rhythm regularity, conduction intervals (such as QT interval), and screens for pre-excitation pathways like WPW syndrome.

24h / 48h Holter Tape

A compact, pocket-sized monitor worn over 24 to 48 hours. Parents keep a simple diary of any symptoms (dizziness, flutter, chest pain) so Dr Naqvi can correlate exact symptoms with recorded heart rhythm.

Frequently Asked Questions: Children's ECG & Holter Monitoring

Common questions answered by Dr Nitha Naqvi

A standard 12-lead ECG records the electrical signals of the heart over 10 seconds. A 24-hour Holter monitor uses a small, lightweight wearable recorder attached to gentle sticky chest patches that continuously tracks the rhythm through normal school, play, and sleep.

No. An ECG is completely non-invasive and painless. Small soft stickers are placed on the arms, legs, and chest, connecting to lightweight wires. No electric shocks or needles are involved.

Children are encouraged to maintain their normal daily routine including school and light exercise. The monitor must be kept dry, so baths and showers are paused for the 24-hour monitoring period.

Many intermittent rhythm anomalies, such as extra ectopic beats, SVT bursts, or nocturnal bradycardia, occur unpredictably and may not appear during a 10-second clinic ECG.
