  2. Benign early repolarization - Wikipedia

    en.wikipedia.org/wiki/Benign_early_repolarization

    Benign early repolarization (BER) or early repolarization is found on an electrocardiogram (ECG) in about 1% of those with chest pain. [2] It is diagnosed based on an elevated J-point / ST elevation with an end-QRS notch or end-QRS slur and where the ST segment concave up. It is believed to be a normal variant.

  3. ST elevation - Wikipedia

    en.wikipedia.org/wiki/ST_elevation

    12-lead electrocardiogram showing ST-segment elevation (orange) in I, aVL and V1–V5 with reciprocal changes (blue) in the inferior leads, indicative of an anterior wall myocardial infarction. When there is a blockage of the coronary artery , there will be lack of oxygen supply to all three layers of cardiac muscle (transmural ischemia).

  4. ST segment - Wikipedia

    en.wikipedia.org/wiki/ST_segment

    In electrocardiography, the ST segment connects the QRS complex and the T wave and has a duration of 0.005 to 0.150 sec (5 to 150 ms). It starts at the J point (junction between the QRS complex and ST segment) and ends at the beginning of the T wave.

    The 2018 European Society of Cardiology/American College of Cardiology Foundation/American Heart Association/World Health Federation Universal Definition of Myocardial Infarction for the ECG diagnosis of the ST segment elevation type of acute myocardial infarction require new ST elevation at J point of at least 1mm (0.1 mV) in two contiguous leads with the cut-points: ≥1 mm in all leads ...

  6. T wave - Wikipedia

    en.wikipedia.org/wiki/T_wave

    ST segments remains neutral in this syndrome. Those who were treated without angiography will develop anterior wall myocardial infarction in a mean period of 9 days. [4] An episode of chest pain in Wellens' syndrome is associated with ST elevation or depression and later progressed to T wave abnormality after chest pain subsided.

  8. Myocarditis - Wikipedia

    en.wikipedia.org/wiki/Myocarditis

    Electrocardiogram findings of ST elevations with upward concavity and an early repolarization pattern, however, were associated with a better cardiovascular prognosis in general. [ 50 ] In cases of acute myocarditis, cardiac magnetic resonance imaging can reveal several prognostic indicators that, similar to ECGs, are non-specific and reflect ...

  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
