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!
