T-axis abnormal range

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… WebJun 16, 2024 · It has been associated with increased risk of AF 6; however, the relationship between abnormal P-wave axis (aPWA) and stroke has not been investigated.
