T-U waves

T-U waves have two peaks from a T wave and a U wave that are fused together. This is also known as a Camel hump T wave. A similar appearance can be seen with hidden P waves that occur during a T wave.

This ECG is from a young woman who presented with status epilepticus seizures and an apparent overdose of bupropion, with possible cocaine ingestion.
