T wave inversion meaning potassium
WebCellular electrophysiological changes. When coronary blood flow is inadequate to support the oxygen needs of the myocardium (i.e., an ischemic state), tissue levels of oxygen fall, which leads to cellular hypoxia. Severe and prolonged hypoxia can ultimately lead to cellular death and total loss of electrical activity. WebThis means that the artifact was caused by which of the following?
