T Wave Lesson and Quiz

T Wave illustration
The T wave indicates the repolarization of the ventricles. It is a slightly asymmetrical waveform that follows (after a pause), the QRS complex. Take note of T waves that have a downward (negative) deflection or of T waves with tall, pointed peaks.

The U-wave is a small upright, rounded bump. When observed, it follows the T-wave.
