The concentration of K+ inside the cell is 30 time more than outside. Hypoxia causes loss of this intracellular Kalium and consequent/premature repolarization when measuring the potential of action. As the all the ECG theory is Vector based, any abnormality in the electric pathways and myocytes will result in changes of ECG. This picture depicts the ST ...
