29 Possible Causes for Lateral Q Wave in USA

  • Hypertrophic Cardiomyopathy
    Lateral Q Wave Q Waves in V6 Inferior Q Wave

    Common electrocardiographic findings include ST-T wave abnormalities and left ventricular hypertrophy, axis deviation (right or left), conduction abnormalities (P-R prolongation … For example, the identification of segmental lateral ventricular hypertrophy cannot be accomplished with echocardiography alone. … The mid-septal bulge aggravates the malposition of the valve and redirects outflow so that it comes from a lateral and posterior direction.[1] [2]

  • Anomalies of Coronary Artery Origin
    Lateral Q Wave Inferior Q Wave
  • Coronary Arteriosclerosis
    Lateral Q Wave Inferior Q Wave

    It leads to heart muscle damage, heart muscle death and later myocardial scarring without heart muscle regrowth.[3]

  • Large Ventricular Septal Defect
    Inferior Q Wave
  • Apical Myocardial Infarction
    Inferior Q Wave
  • Acute Myocardial Infarction
    Inferior Q Wave

    Gradual return to normal ECG findings or development of abnormal Q waves confirm the diagnosis. … These changes are seen on gross pathology and cannot be predicted by the presence or absence of Q waves on an ECG. … In addition to a rise in biomarkers, a rise in the ST segment, changes in the shape or flipping of T waves, new Q waves, or a new left bundle branch block can be used to diagnose … [4] [5]

  • Posterior Myocardial Infarction
    Inferior Q Wave

    Leads V7-V9 show the classical aspect of ST elevation and Q waves. … cardiac ischemia diagnosis, but posterior myocardial infarction is not represented directly on the classical 12 lead recording: horizontal ST depression with tall R and T waves[6]

  • Acute Myocarditis
    Inferior Q Wave

    Acute myocarditis is a potentially life-threatening inflammatory disorder of the myocardium, most commonly caused by viral pathogens such as coxsackie A and B, as well as influenza viruses and other enteroviruses, but an array of infections and autoimmune etiologies have been described. Chest pain, dyspnea, and…[7]

  • Cor Pulmonale
    Inferior Q Wave

    right ventricular hypertrophy, right atrial dilatation, prominent pulmonary artery ECG – right ventricular hypertrophy, dysrhythmia, P pulmonale (characteristic peaked P wave[8]

  • Alcoholic Cardiomyopathy
    Inferior Q Wave

    In fact, it is also beneficial to abstain in later stages as well.   … [9]
