97 Possible Causes for Flattened T Wave, Irregular Heart Rhythm

  • Hypokalemia

    This is most common in people who take digitalis medications (digoxin) or have irregular heart rhythm conditions such as: fibrillation, atrial or ventricular tachycardia ([] […] than the T wave. flattening of the T wave.[] ECG or a heart tracing is done to detect electrical changes in the heart and certain types of irregular heart rhythms that may be caused by low potassium.[]

  • Digitalis Toxicity

    How well a person does depends on the severity of the toxicity and if it has caused an irregular heart rhythm.[] 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[]

  • 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.[]

  • Digitalis

    It’s especially useful in people with irregular heart rhythms, notably atrial fibrillation with a rapid heart rate. What are the expected benefits?[] Irregular heart rhythms (atrial fibrillation) . Taking foxglove by mouth may improve irregular heart rhythms such as atrial fibrillation or flutter.[] How well a person does depends on the severity of the toxicity and if it has caused an irregular heart rhythm.[]

  • Mitral Valve Prolapse

    In addition, some patients with mitral valve prolapse will have irregular heart rhythms that cause palpitations, or in worse cases, may even cause fainting or passing out.[] Irregular heart rhythms most commonly occur in the upper chambers of the heart. They may be bothersome, but aren't usually life-threatening.[] rhythms.[]

  • Digoxin

    It may also be prescribed if you have atrial fibrillation (a common irregular heart rhythm).[] , inverted, or biphasic T waves .[] . - Flattened, negative or biphasic T waves. - QT interval shortening. - U wave amplitude may increase.[]

  • Quinidine

    heart rhythms. — Julie Appleby, Kaiser Health News , "Overwrought Marketing?[] T waves (without dysrhythmia), have occurred frequently and hypotension and ventricular tachycardia have occurred occasionally in patients receiving IV quinidine gluconate[] heart rhythms. — Julie Appleby, Kaiser Health News, "Overwrought Marketing?[]

  • Hypomagnesemia

    You may also notice "jerky" movements, high blood pressure, and irregular heart rhythms with severely low blood magnesium levels.[] 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[] Those with very low levels of magnesium may have muscle weakness, reduced reflex, tremors, hypertension, and irregular heart rhythms.[]

  • Electrolyte Imbalance

    heart rhythms.[] 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[] Electrolytes are needed to keep the body's balance of fluids at the proper level and to maintain normal functions, such as heart rhythm, muscle contraction, and brain function[]

  • Hypokalemic Periodic Paralysis

    Andersen-Tawil syndrome or ATS: People with this type have inconsistent potassium shifts during attacks of paralysis, and may have symptoms of irregular heart rhythms including[] Some electrocardiographic (ECG) findings associated with hypokalemia include flattened or inverted T waves, a U wave and ST depression.[]
