20 Possible Causes for Atrioventricular Dissociation, 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[]

  • Digitalis

    After ROSC was achieved, the electrocardiogram (ECG) showed an idio-ventricular rhythm with atrioventricular dissociation.[]

  • 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[]

  • Cardiac Glycoside Poisoning

  • 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.[]

  • First-Degree Atrioventricular Block

    There are tall, sharply-peaked T waves in many leads. The P waves have not yet widened and lost amplitude, but they will soon flatten out and disappear.[] Data is sparse on an extremely prolonged PR interval associated with Atrioventricular Dissociation and Pseudo-Pacemaker Syndrome.[] Conclusions An extremely prolonged PR interval may occur in First Degree Atrioventricular Block and it may be associated with Atrioventricular Dissociation and Pseudo-Pacemaker[]

  • Lenegre Disease

  • Hyperkalemia

  • Long QT Syndrome

    The other reasons are compounding factors such as heart rate, presence of U-waves, and flattened T-waves. 5 Drug-induced torsades de pointes is a significant cause of morbidity[] In this patient a timely diagnosis and effective management after birth have been life-saving.The intrauterine manifestation of foetal atrioventricular dissociation and ventricular[] , the T wave is flattened or when notching of the T wave occurs.[]
