121 Possible Causes for Left Axis Deviation, T Wave Inversion

  • Left Ventricular Hypertrophy

    […] atrial involvement - terminal deflection of P wave in V1 is 1 box wide, and 1 box deep or more (3 points) Left axis deviation - QRS axis is -30 degrees or more negative ([merckmanuals.com] An electrocardiogram showed atrial fibrillation, with inferolateral T wave inversion, and left ventricular hypertrophy.[ncbi.nlm.nih.gov] LVH by voltage criteria: S wave in V2 R wave in V5 35 mm LV strain pattern: ST depression and T wave inversion in the lateral leads Causes of LVH Hypertension (most common[lifeinthefastlane.com]

  • Inferior Wall Myocardial Infarction

    Note pathologic Q-waves in V1-4, late R wave in V1, wide S waves in lead I, and left axis deviation (-80 degrees).[ecg.utah.edu] Diagnostic T-wave inversion was defined as complete T inversion or biphasic waves with initial, predominantly negative deflection.[ncbi.nlm.nih.gov] On electrocardiography, inferior myocardial infarction exhibits pathological changes in limb leads II, III, and aVF, in the form of ST elevation or depression, and/or T wave[symptoma.com]

  • Hypertrophic Cardiomyopathy

    ECG: Findings also may include right or left axis deviation, conduction abnormalities, sinus bradycardia with ectopic atrial rhythm and atrial enlargement.[patient.info] The most peculiar electrocardiogram findings are giant T-waves inversion in the precordial leads with left ventricular (LV) hypertrophy.[ncbi.nlm.nih.gov] Common electrocardiographic findings include ST-T wave abnormalities and left ventricular hypertrophy, axis deviation (right or left), conduction abnormalities (P-R prolongation[symptoma.com]

  • Aortic Valve Stenosis

    References: [3] [7] [4] Diagnostics ECG Nonspecific for AS Signs of left ventricular hypertrophy (e.g., left axis deviation , positive Sokolow-Lyon index ) Chest x-ray Findings[amboss.com] At this point there may be signs of ventricular strain pattern (ST segment depression and T wave inversion) on the EKG, suggesting subendocardial ischemia.[en.wikipedia.org] […] of left ventricular hypertrophy , such as left ventricular enlargement and rounded heart apex, usually only in decompensated aortic stenosis, and possibly left atrial enlargement[amboss.com]

  • Anomalies of Coronary Artery Origin

    Resting electrocardiogram demonstrated incomplete right bundle branch block and T wave inversion in inferior leads.[ispub.com] The resting electrocardiogram demonstrated incomplete right bundle branch block and T wave inversion in the inferior leads.[ispub.com]

  • Left Ventricular Dilatation

    Biatrial enlargement Left ventricular hypertrophy or biventricular enlargement Left bundle branch block ( RBBB can also occur). Left axis deviation.[lifeinthefastlane.com] There are some signs of left atrial enlargement — leftward deviation of the P wave axis (positive P waves in I and aVL, inverted in III and aVF) and prolongation of the terminal[lifeinthefastlane.com] Right axis deviation suggests associated right ventricular hypertrophy (i.e. biventricular enlargement ).[lifeinthefastlane.com]

  • Right Bundle Branch Block

    LV) anterior wall thinning, n 3), and RBBB LAFB (RBBB with left axis deviation without LV anterior wall thinning n 2).[ncbi.nlm.nih.gov] [ems12lead.com] T Wave T Wave Inversion [medrevise.co.uk] T Wave T Wave Inversion Delayed activation of the right ventricle also gives rise to secondary repolarization abnormalities[symptoma.com] Left bundle branch block is usually associated with normal or left axis deviation.[ncbi.nlm.nih.gov]

  • Left Bundle Branch Block

    Left bundle branch block is usually associated with normal or left axis deviation.[ncbi.nlm.nih.gov] The precordial leads in these patients will demonstrate alarmingly deep, symmetrical T-wave inversions.[ncbi.nlm.nih.gov] His ECG immediately after arrival showed deep T-wave inversion in the precordial leads during normal conduction.[ncbi.nlm.nih.gov]

  • Left Anterior Fascicular Block

    The two current criteria for diagnosis of left anterior fascicular block (LAFB) were evaluated; they are marked left axis deviation (LAD) and a delay in the time of inscription[ncbi.nlm.nih.gov] T-wave inversion may occur in inferior leads and simulate post-ischemic T-waves.[ecgwaves.com] It is caused by only the anterior half of the left bundle branch being defective. It is manifested on the ECG by left axis deviation.[en.wikipedia.org]

  • Left Posterior Fascicular Block

    Verapamil-sensitive, idiopathic left ventricular tachycardia (ILVT) with right bundle branch block configuration and left-axis deviation is known to be due to re-entry mechanism[ncbi.nlm.nih.gov] T-wave inversion may occur in inferior leads and simulate post-ischemic T-waves.[ecgwaves.com] The T wave inversion in leads V1 to V3 could be explained either by the old myocardial infarction or by the right bundle branch block.[cardiophile.org]
