105 Possible Causes for Flattened T Wave, ST Elevation

  • Acute Pericarditis

    Stages 2, 3, and 4 ECG findings consist of ST-segment normalization and T wave flattening, T wave inversion, and normalization of T waves, respectively.[cfp.ca] Electrocardiogram showed ST elevation in inferior-lateral leads.[ncbi.nlm.nih.gov] flatten; stage 3: symmetric T wave inversion throughout ECG; and stage 4: ECG normalization 2 .[jetem.org]

  • Electrolyte Imbalance

    Clinical signs of hyperkalaemia include muscle weakness, hypotension , bradycardia and loss of cardiac output, and ECG changes may include peaked T waves and flattened P waves[ausmed.com] Prognostic importance of hyponatremia in acute ST-elevation myocardial infarction.

  • Pericarditis

    (1 to 3 weeks) Stage 3 – flattened T waves become inverted (3 to several weeks) Stage 4 – ECG returns to normal (several weeks onwards) NB.[lifeinthefastlane.com] This can lead to ST elevation in all leads.[en.ecgpedia.org] Stage 1 – widespread STE and PR depression with reciprocal changes in aVR (occurs during the first two weeks) Stage 2 – normalisation of ST changes; generalised T wave flattening[lifeinthefastlane.com]

  • Angina Pectoris

  • Post-Infarction Pericarditis

    (1 to 3 weeks) Stage 3 – flattened T waves become inverted (3 to several weeks) Stage 4 – ECG returns to normal (several weeks onwards) NB.[lifeinthefastlane.com] Characteristics of ST elevations in STEMI ST elevation myocardial infarction (STEMI) causes localized ST elevations , meaning that there are ST elevations in a few leads which[ecgwaves.com] waves flatten.[merckmanuals.com]

  • Cardiomyopathy due to Anthracyclines

  • Ventricular Aneurysm

    The T wave is usually diminished in height, flattened, or inverted, all findings of a past myocardial infarction (Figures 2 and 3).[journals.lww.com] With an anterior or apical aneurysm, the persistent ST elevation is in lead V1 and V2 with associated Q waves indicating the old anterior MI.[healio.com] Here is his ED ECG: There is ST elevation in V1-V3.
