  2. ST depression - Wikipedia

    en.wikipedia.org/wiki/ST_depression

    Pseudo-ST-depression, which is a wandering baseline due to poor skin contact of the electrode [3] Physiologic J-junctional depression with sinus tachycardia [3] Hyperventilation [3] Horizontal ST depression in V4, V5, V6 leads during a cardiac stress ECG. Other, non-ischemic, causes include: Side effect of digoxin [4] [3] Hypokalemia [4] [3]

  3. ST segment - Wikipedia

    en.wikipedia.org/wiki/ST_segment

    Illustration of ST segment elevation and depression The normal ST segment has a slight upward concavity. Flat, downsloping, or depressed ST segments may indicate coronary ischemia. ST elevation may indicate transmural myocardial infarction. An elevation of >1mm and longer than 80 milliseconds following the J-point.

  4. Cardiac stress test - Wikipedia

    en.wikipedia.org/wiki/Cardiac_stress_test

    A nuclear stress test uses a gamma camera to image radioisotopes injected into the bloodstream. The best known example is myocardial perfusion imaging. Typically, a radiotracer (Tc-99 sestamibi, Myoview or thallous chloride 201) may be injected during the test. After a suitable waiting period to ensure proper distribution of the radiotracer ...

    en.wikipedia.org/wiki/Duke_Treadmill_Score

    The calculation is done based on the information obtained from an exercise test by this formula: [citation needed] [exercise duration by Bruce protocol] - [ 5 × (maximal ST elevation or depression)] - [4 × (treadmill angina index)] In which, the exercise duration is written in "minutes" and the ST changes in "millimetres". [1]

  6. ST elevation - Wikipedia

    en.wikipedia.org/wiki/ST_elevation

    The leads facing the injured cardiac muscle cells will record the action potential as ST elevation during systole while during diastole, there will be depression of the PR segment and the PT segment. Since PR and PT interval are regarded as baseline, ST segment elevation is regarded as a sign of myocardial ischemia.

  9. Strain pattern - Wikipedia

    en.wikipedia.org/wiki/Strain_pattern

    In electrocardiography, a strain pattern is a well-recognized marker for the presence of anatomic left ventricular hypertrophy (LVH) in the form of ST depression and T wave inversion on a resting ECG. [1] It is an abnormality of repolarization and it has been associated with an adverse prognosis in a variety heart disease patients.
