47 Possible Causes for Conduction Disorder of the Heart, Flattened T Wave

  • Digoxin

    Abnormal Heart Rhythms (Heart Rhythm Disorders) Heart rhythm disorders vary from minor palpitations, premature atrial contractions (PACs), premature ventricular contractions[medicinenet.com] , inverted, or biphasic T waves .[lifeinthefastlane.com] ., those with severe heart or renal disease). b Reduce dosage in hypokalemia, hypothyroidism, extensive myocardial damage, or conduction disorders, and in geriatric patients[drugs.com]

  • 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] 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]

  • Quinidine

    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]

  • 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]

  • Accidental Hypothermia

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

  • Second Degree Atrioventricular Block

    I45.9 ICD-10-CM Diagnosis Code I45.9 Conduction disorder, unspecified 2016 2017 2018 2019 Billable/Specific Code Applicable To Heart block NOS Stokes-Adams syndrome second[icd10data.com] 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] Rhythm versus conduction Your heart rhythm is the way your heart beats. Conduction is how electrical impulses travel through your heart, which causes it to beat.[heart.org]

  • First-Degree Atrioventricular Block

    I45.9 ICD-10-CM Diagnosis Code I45.9 Conduction disorder, unspecified 2016 2017 2018 2019 Billable/Specific Code Applicable To Heart block NOS Stokes-Adams syndrome first[icd10data.com] 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.[ecgguru.com] […] on a routine electrocardiogram that signals a disorder of the electrical conducting system in one part of the heart and previously believed to be benign is associated with[cardiobrief.org]

  • Brugada Syndrome

    INTRODUCTION: Brugada syndrome (BrS) is a genetic heart disorder due to alteration of the ion channels function that causes an impaired in the cardiac conduction system.[ncbi.nlm.nih.gov] , the T wave is flattened or when notching of the T wave occurs.[doi.org] (Definition/Background Information) Brugada Syndrome is a disorder that affects the lower chambers of the heart leading to irregular heartbeats and disruption of the heart[dovemed.com]

  • 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]
