The interval from the beginning of the QRS complex to the apex of the T wave is referred to as the absolute refractory period. The last half of the T wave is referred to as the relative refractory period or vulnerable period. The T wave contains more information than the QT interval. The T wave can be described b… pd-l1 22c3 ihc assayWebWith primary T wave changes, the T wave axis is similar to the QRS axis. With secondary changes, the T wave axis is usually opposite to the QRS axis. Another way to look at this is that with primary T wave changes, the T waves follow the same direction as the QRS complexes, with the exception of the abnormal T waves.
