A U-wave is a wave which occurs after the T-wave. It can be made prominent by certain pathologies, particularly certain electrolyte imbalances, but research within the past decade or so has found that it is an essentially normal phenomenon which results from differences in the time it takes various types of cardiac cells to repolarize.
The largest wave in an electrocardiogram is typically the R wave.

The T wave in an electrocardiogram (ECG) represents the repolarization of the ventricles in the heart, indicating the recovery phase before the next heartbeat.

p wave
The key differences between the P wave and T wave in an electrocardiogram (ECG) are that the P wave represents the electrical activity of the atria contracting, while the T wave represents the electrical activity of the ventricles relaxing.
Special training is required for interpretation of the electrocardiogram. To summarize in the simplest manner the features used in interpretations, the P wave of the electrocardiogram is associated with the contraction of the atria
Contraction of both atria
The P wave represents atrial depolarization, the QRS complex represents ventricular depolarization, and the T wave represents ventricular repolarization in an electrocardiogram (ECG).
Potential causes of biphasic T wave changes on an electrocardiogram include myocardial ischemia, electrolyte imbalances, drug effects, and certain cardiac conditions such as hypertrophic cardiomyopathy.
Repolarization of ventricular muscle fibers.
A peaked T wave on an electrocardiogram (ECG) indicates that there may be an abnormality in the heart's electrical activity, which could be a sign of hyperkalemia (high levels of potassium in the blood) or other heart conditions.
