Question
Doctor, my daughter is 11 years old and has undergone radiofrequency ablation to treat supraventricular tachycardia. Now, after the surgery, she has been found to have tachycardia and some abnormal ECG waveforms. I would like to ask if this is a normal postoperative reaction or if there are other issues?
Answer
Hello, based on your description, your daughter’s radiofrequency ablation was for supraventricular tachycardia, and the early beats have already disappeared, indicating a successful surgery. For an 11-year-old child, the normal heart rate range is 60 to 100 beats per minute, and your daughter’s heart rate is 99 beats, which falls at the upper limit of the normal range. I suggest you let your daughter rest for at least 10 minutes before counting her heart rate to get a more accurate reading. If she does not have any discomfort symptoms, she can continue to be observed. Additionally, please confirm that her thyroid function is normal.
