What is the expected electrocardiogram pattern for a patient when a thrombus in a coronary artery lodges permanently in the vessel and the infarction extends through the myocardium from the endocardium to the epicardium?
A) Prolonged Q-T interval
B) ST elevation (STEMI)
C) ST depression (STDMI)
D) Non-ST elevation (non-STEMI)

ST elevation (STEMI) is the expected electrocardiogram pattern for a patient when a thrombus in a coronary artery lodges permanently in the vessel and the infarction extends through the myocardium from the endocardium to the epicardium. This is because the affected myocardium suffers from ischemia and necrosis, leading to abnormal electrical activity in the affected area, which manifests as ST elevation on the ECG. Prolonged Q-T interval, ST depression (STDMI), and non-ST elevation (non-STEMI) may be seen in other forms of cardiac pathology, but not specifically in this scenario.
