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: -T waves represent ventricular repolarization (atrial repolarization is obscured by the large QRS complex).
Detailed explanation-3: -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.
Detailed explanation-4: -T wave is considered flat when the wave varies from-1.0 mm to + 1.0 mm in height. Hypokalemia or digitalis therapy can cause flattened T wave with a prominent U wave. As hypokalemia progressively worsens, T wave becomes more flatten while U wave becomes more prominent, with progressively deeper ST segment depression.
