WebLong-Standing sinus tachycardia may lead to ST-segment depressions on the ECG. Such ST-segment depressions may be seen anywhere but most commonly in leads V3, V4, V5 and V6. The ST-segment tends to be either horizontal or upsloping. Long-standing sinus tachycardia may also cause diminished T-wave amplitude on the ECG. WebThe T wave represents ventricular repolarization. Generally, the T wave exhibits a positive deflection. The reason for this is that the last cells to depolarize in the ventricles are the first to repolarize. How long is a normal T wave? The DURATION of the T Wave is 0.10 to 0.25 seconds or greater. The AMPLITUDE of the T Wave is less than 5 mm.
