WebHeinrich Mattle, Marco Mumenthaler WebJan 4, 2009 · The waves and intervals in a normal ECG are illustrated here. P wave is due to atrial depolarisation. QRS is the ventricular depolarisation and T wave represents ventricular repolarisation. Atrial repolarisation is called Ta wave. Ta wave is not visible because it is shallow and superimposed on the PR segment, QRS and part of the ST segment. im huigher than captain kirk
