Description | Key events | |
Normal ECG before the onset of plaque rupture | ||
Hyperacute T wave changes - increased T wave amplitude and width; QT prolongs; some ST segment elevation | altered repolarization of the involved left ventricle wall is not optimally buffered by the still normal repolarization of septal muscle and right ventricle | If walls of both ventricles are synchronous in repolarization, right ventricle and septal muscle reduce the left ventricle dominance. If the left ventricle wall is delayed, the resulting T wave increases |
Marked ST elevation with hyperacute T wave changes | altered distribution of ventricular charges in diastole and systole displaces the systolic attractor from the diastolic attractor | any asymmetry in the systolic or in the diastolic ventricular electric field changes the position of the thoracic field center in that heart cycle phase. |
Pathologic Q waves appear (necrosis), ST elevation decreases, T waves begin to invert | reduced quantity of repolarised tissue near the “UP” electrode allows the right ventricle structure to prevail during depolarization, when the septal muscle is already depolarized, resulting in Q waves | reduced quantity of tissue able to repolarise near the “UP” electrode allows the septal and right ventricle muscles to prevail and thus Pathologic Q waves and T wave inversion inverse T waves. |
Pathologic Q waves and T wave inversion (necrosis with fibrosis) | ||
Pathologic Q waves, upright T waves (fibrosis) | ||
Q waves may get smaller or disappear with time | cicatrisation physically reduces the electrically “dead” area, so the surrounding muscle can oppose the prevailing right ventricle and septal muscles | The remaining left ventricle muscle tissue becomes able to repolarise and the new electric balance between two walls and septal muscle is achieved. |
