37 Possible Causes for Digitalis Toxicity, Flattened T Wave

  • Digoxin

    , inverted, or biphasic T waves .[] After a careful assessment by the cardiology consultant in charge, she received Digibind infusion for a chronic digitalis toxicity with the digoxin immune Fab dose based on[] Toad venom poisoning is similar to digitalis toxicity and carries a high mortality.[]

  • Hypokalemia

    […] than the T wave. flattening of the T wave.[] Susceptibility to digitalis toxicity is increased when a patient has hypokalemia.[] EMAIL PRINT SAVE EMAIL SAVE The typical ECG findings of hypokalemia (low potassium level) include: U wave that occurs just after the T wave and is usually of smaller amplitude[]

  • Digitalis

    Abstract Digitalis has a clinically useful therapeutic ratio (LD50/ED50), but doses must be carefully adjusted for each patient to avoid manifestations of toxicity.[] Bidirectional tachycardia in a patient with digitalis toxicity. Signs and symptoms Digitalis toxicity produces CNS, visual, GI, and cardiac manifestations.[] Digitoxin is another form of digitalis. Digitalis toxicity can be caused by high levels of digitalis in the body.[]

  • Quinidine

    T waves (without dysrhythmia), have occurred frequently and hypotension and ventricular tachycardia have occurred occasionally in patients receiving IV quinidine gluconate[] Increases digitalis serum levels. Plasma levels decreased by barbiturates, hydantoins, rifampin, nifedipine.[] Increases digitalis serum levels. Quinidine levels decreased by barbiturates, hydantoins, rifampin, nifedipine.[]

  • 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[] Digitalis toxicity may occur either acute or chronic.[] Abstract The principal causes of digitalis toxicity are overdose, reduced volume of distribution, reduced renal elimination, and increased myocardial sensitivity.[]

  • 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[] […] to the development of digitalis toxicity.[] Characteristic ECG changes include progressive QRS complex widening, PR interval prolongation, and flattened T waves.[]

  • Cardiac Glycoside Plant Poisoning

    ECG often reveals an increased PR interval, a decreased QT interval, and T wave flattening or inversion.[] Ma G, Brady WJ, Pollack M, Chan TC (2001) Electrocardiographic manifestations: digitalis toxicity. J Emerg Med 20(2):145–152 PubMed Google Scholar 3.[] […] and anorexia Blurry vision with a yellow tint a nd halos, disorienta tion, weakness Diagnostics : ECG : potentially severe cardiac arrhythmias Premature ventricular beats T-wave[]

  • Myxedema

    Electrocardiographic findings may include bradycardia, varying degrees of block, low voltage, nonspecific ST-segment changes, flattened or inverted T waves, prolonged Q-T[]

  • Hypokalemic Periodic Paralysis

    Some electrocardiographic (ECG) findings associated with hypokalemia include flattened or inverted T waves, a U wave and ST depression.[] Risk of hypokalemia : Hypokalemia increases digitalis toxicity. See: Food high in potassium Other links listed for your convenience: Lab test See Disclaimer[]

  • Accidental Hypothermia

    In hypercalcemia, the ECG shows a shortened QT interval, flattened T waves and QRS widening at very high levels. 4. Atrial fibrillation.[] Multiple other findings eventually develop including a shortened QT interval, ST depression, bundle branch blocks, widened QRS, prolonged PR interval, flattened T wave and[] The ECG manifestations of hyperkalemia begin with peaked T waves.[]
