Coronary angiography is the gold standard for identifying CAD, although it is invasive and not without risk of complication. ST segment deviation (elevation, depression) is measured as the height difference (in millimeters) between the J point and the baseline (the PR segment). This is a slight variation on the classic digoxin pattern: Emergency Physician in Prehospital and Retrieval Medicine in Sydney, Australia. WebThe normal ST segment is flat and isoelectric. ST depression localised to the inferior or high lateral leads is more likely to represent reciprocal change than subendocardial ischaemia. Benign Early Repolarization (BER) causes mild ST elevation with tall T-waves mainly in the precordial leads. Three subjects (6%) had ST depression that was detected on the ambulatory recording only at times other than during the stress test. This encounter shows an irregular rhythm with no P waves present.
