The ST Segment • LITFL • ECG Library Basics
https://litfl.com/st-segment-23.03.2021 · Morphology of ST Depression. ST depression can be either upsloping, downsloping, or horizontal. Horizontal or downsloping ST depression ≥ 0.5 mm at the J-point in ≥ 2 contiguous leads indicates myocardial ischaemia (according to the 2007 Task Force Criteria).Upsloping ST depression in the precordial leads with prominent De Winter T waves is highly specific for …

https://en.my-ekg.com/how-read-ekg/st-segment.html16.09.2021 · Myocardial Ischemia: ST-Segment Abnormalities. The most important cause of ST-segment abnormalities (elevation or depression) is myocardial ischemia.. An electrical disturbance is originated in the myocardial tissue when a heart region is suffering from an important persistent ischemia, causing the ST-segment to shift on the EKG, either a upslope or a downslope, …

Understanding ST depression in the stress-test ECG
pubmed.ncbi.nlm.nih.gov › 17584710Abstract Objective: The electrocardiogram (ECG) obtained during stress testing often shows a typical pattern of primary ST depression. A similar pattern can occur in unstable angina. Current textbooks consider ST depression as a direct result of partial occlusion of a coronary artery. However, animal models could not reproduce this phenomenon.
