Digoxin causes generalized ST segment depressions with a curved ST segment (generalized implies that the depression can be seen in most ECG leads). Figure 15 B.Sympathetic tone and hypokalemia cause ST segment depressions (typically <0.5 mm)....
segment depression is transient, it’s almost always due to acute myocardial ischemia. The ECG ...
Effect of beta-blockade on the interpretation of the exercise ECG: ST level versus delta ST/HR indexThe diagnostic value of exercise-induced ST segment depression is considered to be decreased in patients receiving beta-blockers. One approach to improving predictive accuracy has been to us...

Interpretation and Clinical Course The ECG on admission revealed sinus rhythm of 69 beats per minute with a notable upward convex ST-segment elevation followed by negative T waves in leads V3 to V6. In addition to ST-segment elevation, the ECG also showed embryonic R waves in leads II, III...

Retrospective review of the index ECG indicated that 24 patients (1.8%) did not have diagnostic ST-segment elevation but instead had ST-segment depression, T-wave inversion, or nonspecific ST-T changes, including 3 patients with positive biomarker results (2 with non-STEMI and 1 with a drug ...

In this derived ECG, configuration of the ST segment and T wave is determined by the potential differences during repolarization. Small differences at the very onset of repolarization may be expected to cause deviation of the junction (i.e., J depression) and the early portion of the ST ...
