T wave cause
In electrocardiography, the T wave represents the repolarization of the ventricles. 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… WebT-waves that are higher than 10 mm and 8 mm, in men and women, respectively, should be considered abnormal. A common cause of abnormally large T-waves is hyperkalemia, …

WebFeb 4, 2024 · U -wave size is inversely proportional to heart rate: the U wave grows bigger as the heart rate slows down. U waves generally become visible when the heart rate falls below 65 bpm. The voltage of the U wave is normally < 25% of the T-wave voltage: disproportionally large U waves are abnormal. Maximum normal amplitude of the U wave is 1-2 mm.
