117 Possible Causes for aVR, T Wave Inversion

  • Aortic Valve Stenosis

    Patients were grouped into treatment (aortic valve replacement [AVR]) and conservative (non-AVR) groups.[] At this point there may be signs of ventricular strain pattern (ST segment depression and T wave inversion) on the EKG, suggesting subendocardial ischemia.[] There remains significant morbidity and mortality associated with AVR, and new techniques and technologies for AVR are being developed.[]

  • Pericarditis

    Reciprocal ST depression and PR elevation in V1 and aVR.[] […] have Q waves during evolution ST-segment elevation in middle and left precordial leads, but may be widespread Upward convex ST-segment elevation May have T-wave inversion[] Stage III: In stage III, there are widespread T wave inversions. Stage IV: In stage IV, there is normalization of T waves.[]

  • Acute Myocardial Infarction

    The main wave direction of QRS in lead aVR was positive and showed an extreme right axis deviation.[] Features may initially be normal but abnormalities include new ST-segment elevation; initially peaked T waves and then T-wave inversion; new Q waves; new conduction defects[] His ECG showed ST-segment elevation in precordial (V2-6) and inferior leads (II, III, and aVF) and ST-segment depression in lead aVR.[]

  • Myocardial Infarction

    ECG revealed a diminished R wave in V2-V4 with ST elevation in V2-V5 and in aVR. Biphasic T wave was seen in V2-V6.[] Electrocardiography showed a sinus rhythm with Q-wave formation in the inferior wall leads (II, III, aVF), T-wave inversion in the same leads, and borderline QT prolongation[] ST segment depression and T wave inversion are associated with subendocardial infarction.[]

  • Lateral Wall Myocardial Infarction

    UZMA ANSARI Oct 15, 2010 January 2004 ST elevation ST depression V1-V4, lead I, aVL, often in aVR II, III, aVF (Inferior) often V5 aVL aVR III II 43.[] 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[]

  • Anterior Myocardial Infarction

    ST segment elevation in lead aVR with less ST segment elevation in lead V(1).[] wave inversion, suggesting evolved anterior wall myocardial infarction (AWMI).[] 3 height of R Wave Unless isolated in Lead III T Wave inversion Significant unless isolated to Lead III or Lead V1 T Wave must be at least 1 mm deep ST-T elevation ( 1mm[]

  • Coronary Atherosclerosis

    Although most will recognise the typical ECG features of ST elevation myocardial infarction, the significance of ST elevation in lead aVR may not always be appreciated.[] […] or appearance or disappearance of localized ST-elevation followed by T-wave inversion in two or more standard electrocardiograph leads; (c) increase in concentration of serum[] The ECG can show ST segment shifts and/or T-wave inversions as signs of heart ischemia or injury. However, there are electrically silent areas in the standard monitors.[]

  • Acute Coronary Syndrome

    Small Q waves (ie, 1, V 2, and V 3 ; and lead AVR is often a QS complex normally.[] The ECG shows persistent or transient ST-segment depression or T-wave inversion, flat T waves, pseudo-normalisation of T waves, or no ECG changes at presentation.[] ECG changes such as ST-segment depression, T-wave inversion, or both may be present.[]

  • Left Ventricular Hypertrophy

    Aortic valve replacement (AVR) was scheduled under general anesthesia and CPB.[] An electrocardiogram showed atrial fibrillation, with inferolateral T wave inversion, and left ventricular hypertrophy.[] 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[]
