Possible Causes for Lateral Q Wave in USA

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

    Hypertrophic cardiomyopathy (HCM) is a genetic disorder characterized by left ventricular hypertrophy without an identifiable cause. Most patients have little or no disability and a normal life expectancy. Higher rates of morbidity or mortality are linked to the complications of the disorder, sudden cardiac death,…[1]

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

    Coronary artery disease (CAD), also known as ischemic heart disease (IHD), is a group of diseases that includes: stable angina, unstable angina, myocardial infarction, and sudden cardiac death. It is within the group of cardiovascular diseases of which it is the most common type. A common symptom is chest pain or…[2]

  • Acute Myocardial Infarction
    Inferior Q Wave

    Acute myocardial infarction (AMI) ,colloquially referred to as a heart attack, is an irreversible death of a myocardial segment sequel to persistent occlusion and inadequacy of coronary blood flow to the heart. AMI typically presents with central chest pain which may radiate to the neck, left arm, jaw, and shoulders.…[3]

  • Large Ventricular Septal Defect
    Inferior Q Wave
  • Apical Myocardial Infarction
    Inferior Q Wave
  • Cor Pulmonale
    Inferior Q Wave

    Cor pulmonale is defined as an alteration in the structure and function of the right ventricle of the heart as a response to a disorder of the respiratory system. The chronic form usually leads to right ventricular hypertrophy, the acute form results in dilatation. The symptoms of cor pulmonale, pulmonary heart…[4]

  • Alcoholic Cardiomyopathy
    Inferior Q Wave

    Alcoholic cardiomyopathy is a condition resulting from long-term excessive alcohol intake. This cardiac muscle disease causes an impaired heart performance that leads to cardiac failure. The clinical presentation is dependent on the stage of the heart muscle disease. In the early ACM, patients are…[5]

  • 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…[6]

  • Posterior Myocardial Infarction
    Inferior Q Wave

    Posterior myocardial infarction represents the end result of myocardial ischemia and coronary insufficiency due to acute obstruction of either right or circumflex coronary arteries. It is difficult to diagnose on classical 12 lead electrocardiogram as it only shows indirect signs. Identifying it is easier when it is…[7]
