What does Upsloping ST-segment depression mean?
Background: Slow upsloping ST-segment depression during stress is thought to represent an ischemic response to exercise treadmill testing (ETT).
What does a ST-segment depression on ECG signify?
ST depression in ECG at entry indicates severe coronary lesions and large benefits of an early invasive treatment strategy in unstable coronary artery disease; the FRISC II ECG substudy.
What causes Upsloping ST depression?
Upsloping ST segment depressions which are accompanied by prominent T-waves in the majority of the precordial leads may be caused by an acute occlusion of the left anterior descending coronary artery (LAD).
What does it mean when the ST segment of the Electrogram is elevated?
The ST Segment represents the interval between ventricular depolarization and repolarization. The most important cause of ST segment abnormality (elevation or depression) is myocardial ischaemia or infarction.
What does the ST-segment depression on an ECG mean?
ECG performed at her highest heart rate (Fig. 1) shows sinus tachycardia at a rate of 112 bpm, with a 1-mm horizontal ST-segment depression at 80 ms after the J-point, in the inferolateral leads (II, III, aVF and V4–6), which is suggestive of ischaemia due to obstructive coronary artery disease (CAD).
What causes ST-segment depression in the inferolateral leads?
While ST-segment depression in the inferolateral leads during the treadmill ECG stress test indicates ischaemia from obstructive CAD, we cannot identify the diseased coronary artery from the ST-segment depression alone.
What does slow upsloping ST-segment depression mean?
Background: Slow upsloping ST-segment depression during stress is thought to represent an ischemic response to exercise treadmill testing (ETT).
When does ST segment depression occur during exercise?
Normal (physiological) ST segment depressions occur during physical exercise. These ST segment depressions have an upsloping ST segment. The depression in the J 60 point is usually <1 mm and they resolve rapidly once the exercise is stopped.
