question: hi, im just curios about my ecg result... the interpretation of the ecg personel is sinus rhytm with sinus arrhythmia non specific T wave change. but the QT/QTcB is .586sec/697sec, and the PR interval is .100sec my heart rate is 85 beat per min. QRS is .112sec my blood pressure is 140/80.  is that fit to work?
