44 Possible Causes for aVR, Cerebral Embolism, T Wave Inversion

  • Aortic Valve Stenosis

    Patients were grouped into treatment (aortic valve replacement [AVR]) and conservative (non-AVR) groups.[ncbi.nlm.nih.gov] 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] Complications congestive heart failure sudden cardiac death from arrhythmia aortic valve regurgitation calcified cerebral embolism Heyde syndrome valvular heart disease general[radiopaedia.org]

  • Acute Myocardial Infarction

    The main wave direction of QRS in lead aVR was positive and showed an extreme right axis deviation.[ncbi.nlm.nih.gov] 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[patient.info] […] the cerebral circulation (paradoxical embolism).[pediatrics.aappublications.org]

  • 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.[ncbi.nlm.nih.gov] 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[ncbi.nlm.nih.gov] Alternatively, a thrombus can embolize from elsewhere in the body and become lodged in the cerebral vasculature ( Caplan 2009 ).[doi.org]

  • 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.[ncbi.nlm.nih.gov] […] 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[doi.org] 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.[emedicine.com]

  • Ventricular Aneurysm

    Prominent R wave in lead aVR (Goldberger sign) The presence of above ECG findings are not pathognomonic for the presence of LVA.[metealpaslan.com] ECG Examples Example 1 Anterior Left Ventricular Aneurysm: Minimal ST elevation in V1-3 associated with deep Q waves and T-wave inversion.[lifeinthefastlane.com] Lead aVR shows prominent R waves (Goldberger sign).

  • Acute Bacterial Endocarditis

    Homograft use for aortic valve replacement (AVR) in aortic valve acute bacterial endocarditis (ABE) has gained in popularity, due mainly to the relative resistance of homografts[ncbi.nlm.nih.gov] wave inversion may be secondary to conduction system invasion or underlying predisposition (e.g. aortic stenosis ) The following conditions appear to play critical roles in[radiopaedia.org] Subacute bacterial endocarditis can develop from modest to moderate systemic symptoms: cerebral, renal, splenic or mesenteric embolism, heart failure, or any combination of[remedyland.com]
