23 Possible Causes for Flattened T Wave, Manic Behavior

  • Lithium Toxicity

    Cardiovascular side effects are usually mild and manifest as nonspecific ECG changes, such as ST-T flattening and T-wave inversion.[calpoison.org] During a manic episode, those affected may be euphoric, irritable, have high energy and grandiose ideas, use poor judgment, and participate in risky behaviors.[labtestsonline.org] The most common electrocardiographic finding is T-wave flattening.[emedicine.medscape.com]

  • 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[medical-dictionary.thefreedictionary.com]

  • Electrolytes Abnormal

    Hypokalemia Electrocardiographic findings associated with Hypokalemia are flattened T waves, ST segment depression and prolongation of the QT interval.[eurekaselect.com] Electrocardiographic (ECG) changes can occur and include flattening or inversion of T waves, prominent U waves, and ST-segment depression and arrhythmias.[musculoskeletalkey.com] EKG changes can include increased amplitude and width of P wave, T wave flattening and inversion, prominent U waves and apparent long QT intervals due to merging of the T[cdemcurriculum.com]

  • Salicylate Poisoning

    , flattened T waves, QT prolongation; may reflect hypokalemia 16.[slideshare.net] […] tachycardia, ventricular fibrillation, multiple premature ventricular contractions  Asystole - With severe intoxication  Electrocardiogram (ECG) abnormalities - Eg, U waves[slideshare.net]

  • Cardiac Glycoside Plant Poisoning

    ECG often reveals an increased PR interval, a decreased QT interval, and T wave flattening or inversion.[roaic.eg.net] […] 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[amboss.com] […] inversion or flattening Downsloping ST segment depression (“scooped” ST segments) QT interval PR interval Atrial tachycardia with AV block Laboratory studies Serum digoxin[amboss.com]

  • Barbiturate Withdrawal

    […] or inversion of T-waves; Miscellaneous — fatigue, lethargy, transient scotomata. dehydration, weight loss, tendency to sleep... ‏[books.google.com] الصفحة 295 - Changes — diffuse slowing, widening of the frequency spectrum, potentiation and disorganization of background rhythm; EKG Changes — Reversible flattening, isoelectricity[books.google.com]

  • Thyroxine

    Cardiovascular effects of hypothyroidism can include electrocardiographic changes, such as bradycardia, right bundle branch block, flattened or inverted T waves, QRS prolongation[thyroidresearchjournal.biomedcentral.com] The 12 lead, surface electrocardiogram revealed the presence of low QRS voltages and flattened and inverted T waves, all findings suggestive of and compatible with hypothyroidism[thyroidresearchjournal.biomedcentral.com]

  • Cardiac Glycoside Poisoning

    […] 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[amboss.com] […] inversion or flattening Downsloping ST segment depression (“scooped” ST segments) QT interval PR interval Atrial tachycardia with AV block Laboratory studies Serum digoxin[amboss.com]

  • Tricyclic Antidepressant Overdose

    The patient’s EKG shows a widening of the QRS resulting in a wide QT interval with T wave inversion and/or flattening in various leads.[ems1.com]

  • Pesticide Poisoning

    The electrocardiogram (ECG) was also abnormal, demonstrating sinus tachycardia, left axis deviation, poor R-wave progression, and diffuse T-wave flattening ( Fig 1 ).[hosppeds.aappublications.org] FIGURE 1 Electrocardiogram obtained at initial cardiology evaluation demonstrating sinus tachycardia, left axis deviation, poor R-wave progressive, and diffuse T-wave flattening[hosppeds.aappublications.org]
