103 Possible Causes for aVR, Premature Ventricular Contraction, T Wave Inversion

  • 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[] The prophylactic administration of lidocaine to suppress premature ventricular contractions or prevent ventricular tachycardia/fibrillation is not recommended.[]

  • 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[] Although VT/VF is associated with higher 90-day mortality risk, premature ventricular contractions not associated with hemodynamic compromise and accelerated ventricular rhythms[]

  • 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.[]

  • Mitral Valve Prolapse

    ARD 45mm One pregnancy without complication, Surgery for threatened aortic dissection First Son MVP, MR, AI ARD 47mm No Second Son MVP, MR Surgery for aortic dissection & AVR[] inversion in I–aVL; Q wave in inferior leads T-wave inversion in V 1 –V 2 T-wave inversion in V 1 –V 3 T-wave inversion in V 1 –V 3 Echocardiographic findings Maximal septal[] BACKGROUND: In patients with frequent premature ventricular contractions (PVCs), little is known about the profile of PVCs and the outcome of treatment in patients with mitral[]

  • Ischemic Cardiomyopathy

    Amplitudes of T/aVR were automatically computed from median ECG beats at enrollment and endpoints were blindly adjudicated.[] Premature ventricular contractions (PVCs) can cause clinical deterioration in patients with heart failure and increase the frequency of shocks delivered by an implantable[] The electrocardiogram (ECG) monitor revealed frequent premature ventricular contractions (PVCs) initiated PVT/VF.[]

  • 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[] […] assist device (VAD)心室補助人工心臓、心室補助装置 ventricular fibrillation (VF, Vf)心室細動 ventricular premature contraction (beat)(VPC)心室期外収縮 ventricular septal defect (VSD) 心室中隔欠損[症] ventricular[]

  • 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).[] Sinus tachycardia (compensatory mechanism for lower cardiac output), premature atrial contractions (PACs), Second Degree Type II heart block, and premature ventricular contractions[]

  • Right Bundle Branch Block

    We investigated clinical and ECG characteristics, including maximum deflection index and QRS morphology in leads aVR and V6.[] 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[] This is the case in premature ventricular contractions that arise from the left ventricle, which take time to travel to the right ventricle, thereby resulting in a RBBB QRS[]

  • Arrhythmogenic Right Ventricular Dysplasia

    New algorithm using only lead aVR for differential diagnosis of wide QRS complex tachycardia. Heart Rhythm . 2008 Jan. 5 (1):89-98. [Medline] . Kannankeril PJ, Roden DM.[] The patient had T-wave inversion in the inferior ECG leads and no history of arrhythmias.[] Premature ventricular contractions (PVCs) are an important measure in determining disease severity and constitute a minor criterion in the 2010 Task Force Criteria for the[]

  • Acute Coronary Syndrome

    Small Q waves (ie, 1, V 2, and V 3 ; and lead AVR is often a QS complex normally.[] Ventricular arrhythmias: simple and complex premature ventricular contractions and non-sustained ventricular tachycardia Atrioventricular nodal blockade: usually transient[] ECG changes such as ST-segment depression, T-wave inversion, or both may be present.[]
