What causes irregular heartbeat in a child?
Patient: My 5 year old son wakes up during the night and has an irregular heartbeat when he wakes. The heartbeat has long pauses, but not all the same length in time. He also stops breathing for periods of time during sleep as well. Is this something that needs immediate medical attention? Doctor: Hello,  Yes, you need to consult a pediatrician for the above problem. 24 hours ECG monitoring also available nowadays to diagnose exactly what is the problem.  Hope I have answered your query. Let me know if I can assist you further.  Take care  Regards, Dr Rajmohan, Pediatrician
