225 Possible Causes for Flattened T Wave

  • Digitalis Toxicity

    Electrocardiographic signs of digitalis toxicity include first-degree atrioventricular (A-V) block with depressed S-T segments, shortened Q-T intervals, and flattened T waves[]

  • Hypokalemia

    T waves U waves Prolonged QT Interval Non-specific ST segment changes Note: Hypokalemia is a common predisposing condition for Torsades de Pointes Urine potassium level ([] Diagnostic Test Results-Diagnostic Procedures Characteristic electrocardiogram changes may be seen, including flattened T wave and depressed ST segment and U wave.[] EKG changes show a flattened T wave with an eventual emergence of a prominent U wave. The ST segment is depressed with a slightly peaked P wave.[]

  • 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.[] flatten; stage 3: symmetric T wave inversion throughout ECG; and stage 4: ECG normalization 2 .[] (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.[]

  • Hypokalemic Periodic Paralysis

    SERUM POTASSIUM CONCENTRATION LOW ECG U waves, flattening of T waves MUSCLE BIOPSY SINGLE OR MULTIPLE CENTRALLY PLACED VACUOLES NERVE CONDUCTION TEST REDUCED AMPLITUDE OF[] Prolongation of the PR and QT intervals and T-wave flattening are associated with prominent U-waves.[] Some electrocardiographic (ECG) findings associated with hypokalemia include flattened or inverted T waves, a U wave and ST depression.[]

  • Digoxin

    , inverted, or biphasic T waves .[] . - Flattened, negative or biphasic T waves. - QT interval shortening. - U wave amplitude may increase.[] […] demonstrating the Digoxin Effect Digoxin effect refers to the presence on the ECG of: Downsloping ST depression with a characteristic “Salvador Dali sagging” appearance Flattened[]

  • Lithium Toxicity

    Cardiovascular side effects are usually mild and manifest as nonspecific ECG changes, such as ST-T flattening and T-wave inversion.[] The most common electrocardiographic finding is T-wave flattening.[]

  • Electrolyte Imbalance

    Electrocardiographic manifestations of hypokalemia include a flattened T wave, prolongation of the QT interval, or the appearance of U waves.[] 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[]

  • Angina Pectoris

    ST-segment and T-wave abnormalities (eg, flattening or inversion). FBC is required to exclude anaemia. Renal function and electrolytes to assess renal function.[] Changes on a resting 12-lead ECG that are consistent with CAD include: Pathological Q waves. Left bundle branch block (LBBB).[]

  • Hypomagnesemia

    t-waves, C hvostek’s sign (positive which goes along with hypocalcemia) H ypertension, h yperreflexia I nvoluntary movements N ausea G I issues (decreased bowel sounds and[] Characteristic ECG changes include progressive QRS complex widening, PR interval prolongation, and flattened T waves.[] ECG signs may include wide QRS complexes, a prolonged QT interval, flattened T waves and the presence of U waves. Associated metabolic abnormalities as above.[]

  • Minoxidil Topical

    She presented electrocardiogram changes (sinus tachycardia and flattening T-waves) but normal cardiac enzymes.[]
