17 Possible Causes for Flattened T Wave, Paroxysmal Atrial Tachycardia with Block

  • Digitalis Toxicity

    Though no single dysrhythmia is always present, certain aberrations such as frequent premature ventricular beats, bradydysrhythmias, paroxysmal atrial tachycardia with block[ncbi.nlm.nih.gov] 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] Rhythms that especially suggest digitalis toxicity include paroxysmal atrial tachycardia with block, non-paroxysmal accelerated junctional tachycardia, bi-directional VT,[calsprogram.org]

  • Digoxin

  • Digitalis

    Abstract A 19-year-old female was admitted to our department because of a hypertrophic palmaris digitalis II of the left hand displaying color changes. A thrill was easily palpated over the medial part of the finger. A review of her history revealed that this hypertrophy occurred after a blunt trauma to the left[…][ncbi.nlm.nih.gov]

    These symptoms may include cardiac arrhythmias and electrocardiogram abnormalities such as ventricular tachycardia/ventricular fibrillation, paroxysmal atrial or junctional[acls.com] […] than the T wave. flattening of the T wave.[healio.com] These ECG changes can lead to various arrhythmias, including heart block, atrial flutter, paroxysmal atrial tachycardia, and ventricular fibrillation.[ncbi.nlm.nih.gov]

  • Quinidine

    Premature atrial, AV junctional, and ventricular contraction; paroxysmal atrial tachycardia, chronic ventricular tachycardia (when not associated with complete heart block[robholland.com] T waves (without dysrhythmia), have occurred frequently and hypotension and ventricular tachycardia have occurred occasionally in patients receiving IV quinidine gluconate[drugs.com] […] measures may be required. b While substantial cardiovascular toxicity generally has not occurred, ECG changes, including prolonged QT interval, widened QRS complex, and flattened[drugs.com]

  • Cardiac Glycoside Poisoning

  • Second Degree Atrioventricular Block

    Abstract Paroxysmal atrial tachycardia with atrioventricular block usually indicates potentially dangerous overdigitalization, and serious heart disease is almost universally[ncbi.nlm.nih.gov] This patient has some minor flattening of the ST segments in Lead III, but the T wave inversion can be explained by the RBBB.[ecgguru.com]

  • Neurocirculatory Asthenia

    Sometimes there paroiksizmalna supraventricular tachycardia, rarely paroxysmal atrial fiibrilacija.[corhealthy.blogspot.com] Such variations as transient S-T segment deviation 3, 4 and T-wave flattening or inversion 2 are among those considered to be due to neurocirculatory asthenia.[annals.org] Partly be seen and AV block, which can be corrected with atropine (diagnostic test).[corhealthy.blogspot.com]

  • Hyperkalemia

    These symptoms may include cardiac arrhythmias and electrocardiogram abnormalities such as ventricular tachycardia/ventricular fibrillation, paroxysmal atrial or junctional[acls.com] P wave flattening, may disappear increased amplitude and width PR interval prolonged prolonged QRS interval prolonged ST segment slight depression T wave increased amplitude[rccc.eu] Flattened P-waves Widened QRS complex Deep S-waves Eventually, merging of S and T waves Trend towards sine-wave at K over 7mmol/L Management of hyperkalemia The recommendations[derangedphysiology.com]

  • Diffuse Intraventricular Block
