Irregular Bony trabeculae That will cause the deformities that make the disease famous. What that means is that the bone will grow tumor-like fibrous (scar) tissue instead of the normal medullary (bone marrow) bone tissue.
Papillary muscle rupture –> severe Mitral regurgitation.Localization of infarct: TIMELINE: MI Complications If the size of the infarct was small, Q wave goes back to normal. End of 3m: only Q wave stays the same, ST segm and T wave return to normal.3°w: Q wave fully developed + T wave starts becoming flat.(If ST segment stays elevated >6m, think of development ventricular aneurism) 7°d: ST segment starts returning to base level + T wave inverted + Q wave starts appearing, it deepens.2-3°d: ST segment still elevated + T wave slowly becomes inverted.1°d: ST segment elevation + tall T wave.Q wave = muscle death, appears after 1 week, and gradually deepens and remains permanent.T wave becomes inverted after 2 days, and remains like that for 3w, and gradually becomes flat and then upright over 2-3m.Elevation of ST segment stays for 2-3d and gradually goes back to base level in 1-2w.With reciprocal changes in the leads facing the opposite wall:Ĭhanges do not appear at the same time.
