Intraventricular Conduction Disorders: Clinical Significance and Prognosis

Intraventricular conduction (IVC) disorders are one of the most common changes which are determined on the electrocardiogram. The clinical significance of these changes is not the same and depends on the variant, degree, level of conduction disorder, as well as the presence or absence of cardiovascular pathology of the heart, in particular hypertrophy, dilatation, focal changes or fibrosis of the myocardium. The presence of IVC disorders can significantly complicate the electrocardiographic diagnosis of myocardial pathology, including acute pathology, in particular acute myocardial infarction. Conduction disorders can appear as a complication of the underlying disease. His bundle block leads to asynchronous contraction of the ventricles, which can negatively affect the functional state of patients and reduce the effectiveness of their treatment. The article presents modern methods and indications for non-drug treatment of patients with IVC disorders, including in combination with heart failure.
