Several factors can lead to changes in the ST segment:
- Myocardial ischemia: Reduced blood flow to the heart muscle can cause ST depression. - Myocardial infarction: Heart attack typically presents with ST elevation. - Electrolyte imbalances: Abnormal levels of potassium or calcium can affect the ST segment. - Pericarditis: Inflammation of the pericardium may cause widespread ST elevation.
