- Transmural myocardial infarction is an area of ischemic necrosis that extends through the full thickness of myocardial wall, including the endocardium, myocardium, and epicardium1. It is characterized by abnormal Q waves on ECG2. The progression of wall infarction starts from the least perfused region of the heart, the endocardial and subendocardial zones1. Nontransmural infarcts do not extend through the ventricular wall and cause only ST-segment and T-wave (ST-T) abnormalities2.Learn more:✕This summary was generated using AI based on multiple online sources.
