Took my 14 year old for blood work and ekg today due to the fact that she came to me saying feels like her heart skips a beat. unconfirmed ekg say normal sinus rhythm, left axis deviation and borderline prolonged qt. Any thoughts to help me ease my mind while Iam waiting to hear back from md especially since its a Friday
There are many variants of normal in ECGs. Although a left axis deviation is considered "abnormal" there are normal children with a left axis deviation on ECG. Similarly, the QTc interval in females should not exceed 0.46 seconds. There are some patients who are normal who have QT intervals that are in this range or slightly higher. If your daughter has symptoms that suggest a possible arrhythmia and the final read out on the ECG is "abnormal" then getting a formal pediatric cardiology consultation is the next step. Many times the outcome is benign extra beats or maybe even nothing at all. But you are doing the proper thing to not ignore her symptoms.
