my 13 yr old son had some sort of episode at school, (inflammation of cartilage at breast plate and ribs that caused his breathing at heart rate to change. in 2008 he was DX with an arrhythmia that he would out grow. I got a copy today of his ecg done in the ER. ( school sent him to ER) and it states: vent rate: 56 bpm, PR int. 131 ms, QRS dur: 109, QT/QRc: 402/394 ms, PRT axes: 128 73 116. Sinus bradycardia with sinus arrhythmia; RSR (QR) in V1/V2 consistent with right ventricular conduction delay. Moderate ST depression. Abnormal ECG. I am worried due to all the electrical implications this may have, I have WPW . He plays football and I want to make sure he will be ok if he plays.
