ECG T-wave disorders

The T wave is the part of the ECG which shows the repolarisation of the ventricles - that is, it's the part where the ventricles come back into a position where they are no longer refractory - where they can start to accept another electrical impulse. It's the part of the ECG where the ventricles 'return to base', ready to receive their next instructions. It is read as a single bump following the QRS complex.
