171 Possible Causes for Right Axis Deviation, T Wave Inversion

  • Anterior Myocardial Infarction

    […] precordial R waves) Pulmonary emphysema and cor pulmonale (loss of R waves V1-3 and/or inferior Q waves with right axis deviation) Left anterior fascicular block (may see[] wave inversion, suggesting evolved anterior wall myocardial infarction (AWMI).[] Biphasic/inverted T waves in V1-5. Poor R wave progression (R wave height 3mm in V3). Abnormal Q waves and T-wave inversion in I and aVL.[]

  • Lateral Wall Myocardial Infarction

    If the QRS is negative in Lead I, the heart is pointing more to the right than normal; hence, Right Axis Deviation.[] These feature are suggestive of posterior wall infarction, being the inverse of Q wave, ST elevation and T wave inversion which would have been recorded in a posterior lead[] In 8 of these 22 patients, the infarct was silent in the sense that no ST segment elevation or Q waves were seen, although ST depressions or T wave inversions, or both, in[]

  • Ostium Primum Atrial Septal Defect

    In Primum defects left axis deviation is seen in most patients with an axis of -30 degrees and very few patients have right axis deviation.[] Electrocardiogram showed sinus rhythm with a rightward axis deviation, dominant R in V1, and T wave inversion in V1–V3, III, and aVF, which are all suggestive of right ventricular[] Normal axis or right axis deviation due to right ventricular diastolic overload. Right atrial abnormality ( may not be observed in children ).[]

  • Dilated Cardiomyopathy

    Right axis deviation suggests associated right ventricular hypertrophy (i.e. biventricular enlargement ).[] Takotsubo cardiomyopathy is characterized by the basal hypercontractility and apical ballooning of the left ventriculum and T-wave inversion in the electrocardiogram.[] The main role of ECG is to detect evidence of myocardial ischemia (pathologic Q waves with ST elevation and T wave inversion in leads I, aVL, V 5 , V 6 ) that might point[]

  • Left Posterior Fascicular Block

    axis deviation, alongside several other findings involving the QRS complex.[] T-wave inversion may occur in inferior leads and simulate post-ischemic T-waves.[] 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.[]

  • Cor Pulmonale

    Right axis deviation and low voltage may be noted in patients with pulmonary emphysema.[] […] interventricular septal shift on the short-axis view) Electrocardiographic clues such as right axis deviation; rightward axis shift; right bundle branch block; right precordial T-wave[] Electrocardiography shows the appearance of flat or inverted T waves in the right ventricular precordial leads, right axis deviation of greater than 30 in the mean electrical[]

  • Right Bundle Branch Block

    Also this case focuses attention on changing axis deviation and intermittent right bundle branch block during acute myocardial infarction.[] Typical RSR’ pattern (‘M’-shaped QRS) in V1 Wide slurred S wave in lead I Typical pattern of T-wave inversion in V1-3 with RBBB Causes of Right Bundle Branch Block Right ventricular[] Changing axis deviation with intermittent right bundle branch block in a patient admitted with acute myocardial infarction has been also described.[]

  • Pulmonary Hypertension

    Surface electrocardiogram showed right atrial and ventricular overload with right axis deviation.[] On multivariable logistic regression analysis, S wave depth in lead V5 (odds ratio [OR] 1.25, 95% confidence interval [CI] 1.10-1.47) and depth of T wave inversion in lead[] 33 Cl 101 Plt 350 HCO3 19 HCO3 19 pO2 24 Cr 142 (101 baseline) Lactate 5.0 Glc 6.0 Urea 12.1 Troponin 0.02 ECG Old ECG ECG interpretation: RBB, RAD, anterior and inferior T-wave[]

  • Spontaneous Pneumothorax

    These findings include axis deviation, T-wave inversion, and right bundle branch block.[] These findings include axis deviation, T-wave inversion, and right bundle branch block.[] When an ECG has the arm leads incorrectly placed, the ECG will display right axis deviation and inversion of the P waves in lead I.[]

  • Restrictive Cardiomyopathy

    An electrocardiogram showed an atrioventricular-block I, paroxysmal sinus-tachycardia, biphasic P-waves, right-axis deviation, abnormal repolarization, and episodes of supraventricular[] LV, left ventricle; RV, right ventricle; RA, right atrium. ( b ) 12-lead ECG in sinus rhythm with prominent P-waves in all leads, T-wave inversions, and incomplete right bundle[] Standard 12-lead ECG revealed: sinus rhythm 72 bpm, minor right axis deviation, left atrial enlargement, incomplete right bundle branch block RSR’ in V1, tall R waves in RV[]
