Editing T wave (section)

== Normal T wave ==
Normally, T waves are upright in all leads, except aVR and V1 leads. Highest amplitude of T wave is found at V2 and V3 leads. The shape of the T wave is usually asymmetrical with a rounded peak. T wave inversions from V2 to V4 leads are frequently found and normal in children. In normal adults, T wave inversions from V2 to V3 are less commonly found but can be normal.<ref name= "WeiQin 2013"/> The depth of the T wave also becomes progressively shallow from one to the next lead.<ref name="Hanna 2011"/> The height of the T wave should not exceed 5&nbsp;mm in limb leads and more than 10&nbsp;mm in precordial leads.<ref name= "WeiQin 2013">{{cite journal|last1=Wei Qin|first1=Lin|last2=Swee|first2=Guan Teo|last3=Kian Keong|first3=Poh|title=Electrocardiographic T wave abnormalities|journal=Singapore Medical Journal|date=2013|volume=54|issue=11|pages=606–610|doi=10.11622/smedj.2013218|url=http://www.smj.org.sg/sites/default/files/5411/5411es1.pdf|access-date=18 April 2018|doi-access=free}}</ref>
