T wave represent on an electrocardiogram
WebAn ECG (electrocardiogram) is a test to check the electrical activity of the heart. ECG measures the atrial and ventricular depolarization and repolarization in the form of waves. It comprises of three waves, namely P wave, QRS complex and T wave. P wave in ECG represents atrial depolarization. QRS complex represents ventricular depolarization. WebU wave amplitude is usually < 1/3 T wave amplitude in same lead. U wave direction is the same as T wave direction in that lead. U waves are more prominent at slow heart rates and usually best seen in the right precordial leads. Origin of the U wave is thought to be related to after depolarizations which interrupt or follow repolarization.

WebT wave: The T wave represents the repolarization of the ventricles, which is the recovery of the electrical charge of the ventricles after depolarization. The T wave is usually rounded and slightly asymmetrical, with a duration of between 160 and 240 milliseconds. Other waves and intervals in an ECG signal include:
