Have Rett Syndrome. EKG Shows Rapid Sinus Rhythm, Flat Or Low Negative T In AVF. Have Rapid Respiratory Rate

Hi my daughter is 26 years old and has Rett syndrome (neurological disorder). Had EKG today to check for Long QT interval, which is fairly common in Rett. She did not show signs of that but doctor is sending to cardiologist due to some other issues seen. This is what the printout said: sinus rhythm (rapid); RSR' in V1 and V2, slight right-precordial repolarization disturbance, consider ischemia, LV overload or aspecific change; flat or low negative T in aVF with negative T in III; ECG w/out significant abnormalities. (P/PR 94/124 ms; QRS: 94 ms; QT/QTc: 354;435 ms; P/QRS/T Axis: 38/71/6 deg; Heart rate: 91 BPM. Side note: She often has rapid respiratory rate, hyperventilate breathes, and has breatholding spells...all related to Rett. Curious if any of these issues contribute to some of her abnormalities in the ECG. Waiting on call from cardiologists office to schedule appointment. Thank you for any insight!

Cardiologist,  's  Response
Dear Sir/ Madam
Thanks for writing to HCM.
1. Any ECG read in clinical context only with full knowledge of history and examination findings. Moreover it must be seen by the cardiologist for exact interpretation. I explain the ECG report with this rider.
2. RSR' in V1 and V2, with normal QRS duration (94 ms) does not indicate an abnormality. This can be perfectly normal. Flat or low negative itself do not carry any value. Rest all parameters are normal except for negative T in III which should be at least 2 mm to be significant. Overall does not seem to be alarming. Do see your cardiologist.
Sincerely
Sukhvinder
