What is the cause of T wave inversion in bundle branch blocks?<\/span><\/h2>\n

In the normal heart, depolarization is from subendocardial region to epicardial region, that is inner layer to outer layer and repolarization is from epicardium to subendocardial region. That is why both depolarization wave, the QRS complex and repolarisation wave, the T wave are both upright or in the same direction. Even though subendocardium is the first region to depolarised, the high intracavitary pressure of the left ventricle prevents repolarisation of the subendocardium from starting earlier.<\/p>\n

When depolarization sequence is abnormal as in bundle branch block or\u00a0WPW\u00a0syndrome, repolarization is from subendocardial region to epicardial region. That is why T waves get inverted.<\/p>\n","protected":false},"excerpt":{"rendered":"
