MEDICAL PHYSIOLOGY

Detailed explanation-1: -Normally, the T wave on an electrocardiogram (ECG) is representative of ventricular repolarization. Changes in T wave morphology can be indicative of various benign or pathologic conditions affecting the myocardium.

Detailed explanation-2: -Ventricular repolarization is a complex electrical phenomenon which represents a crucial stage in electrical cardiac activity. It is expressed on the surface electrocardiogram by the interval between the start of the QRS complex and the end of the T wave or U wave (QT).

Detailed explanation-3: -The electrocardiographic (ECG) manifestation of ventricular repolarization includes J (Osborn), T, and U waves. On the basis of biophysical principles of ECG recording, any wave on the body surface ECG represents a coincident voltage gradient generated by cellular electrical activity within the heart.

Detailed explanation-4: -The T Wave indicates ventricular repolarization, in which the ventricles relax following depolarization and contraction. The ST segment refers to the gap (flat or slightly upcurved line) between the S wave and the T wave, and represents the time between ventricular depolarization and repolarization.
