Clinicians who want a deeper understanding of ischemia and infarction often benefit from resources that explain why the ECG behaves as it does, rather than relying solely on pattern recognition. The following five articles explore the mechanisms behind ischemia‑related ECG changes, the subtleties clinicians frequently overlook, and the physiologic principles that distinguish ischemia from infarction. Each article provides a focused, clinically relevant perspective that supports deeper study of myocardial injury and its electrocardiographic expression.
1. Why Ischemia Is NOT an Infarction: A Mechanism‑Based Explanation for Clinicians
A foundational review of the physiologic differences between ischemia, injury, and infarction — and how these distinctions shape ECG interpretation. Related article: Why Ischemia Is NOT an Infarction
2. How Myocardial Ischemia Alters the ECG: From Injury Currents to ST‑Segment Shifts
A mechanism‑centered discussion of how ischemia generates ST‑segment and T‑wave changes, including injury vectors, subendocardial vs transmural patterns, and the origins of reciprocal changes. Related article: How Myocardial Ischemia Alters the ECG
3. Recognizing Subtle Ischemia: The ECG Patterns Clinicians Miss Most
A practical, high‑yield review of early or minimal ischemic findings — including hyperacute T waves, borderline ST depression, and early reciprocal changes — with emphasis on mechanism‑based interpretation. Related article: Recognizing Subtle Ischemia
4. Inferior, Posterior, and Lateral Ischemia: What the ECG Really Shows
A regional, anatomy‑driven exploration of ischemia patterns, focusing on coronary supply territories, posterior injury recognition, and how dominance affects ECG appearance. Related article: Inferior, Posterior, and Lateral Ischemia
5. When Chest Pain Isn’t an MI: ECG Clues That Point Away From Infarction
A differential‑diagnosis article that clarifies how to distinguish ischemia from non‑ischemic ST‑T abnormalities such as pericarditis, early repolarization, LVH with strain, and conduction‑related changes. Related article: When Chest Pain Isn’t an MI
