Treatment such as insertion of a pacemaker is available if complete heart block becomes imminent. The prognosis of bundle branch blocks depends on what caused the disorder, and whether the conduction disturbs progress. Prognosis of Intraventricular Conduction Blocks Cardiac enzymes may be elevated if the bundle branch block is secondary to an acute myocardial infarction, but only if this is an acute event. A chest x-ray will show any obvious ventricular disease such as hypertrophy or cardiomyopathies – Blood Tests should exclude electrolyte imbalances as a cause of bundle branch block. How is Intraventricular Conduction Blocks Diagnosed? The importance of bundle branch blocks is that they can indicate conduction disease of the heart, and they may progress to complete heart block. For instance right bundle branch block results in delayed right ventricular contraction and left bundle branch block causes delayed left ventricular contraction. Progression of Intraventricular Conduction BlocksĪ block of either branch of the ventricular conducting system produces a de-coordination of the contraction of the two ventricles (the left and the right). Risk Factors for Intraventricular Conduction BlocksĬauses of a right bundle branch block include:Ĭauses of a left bundle branch block include myocardial disease, particularly myocardial infarction, left ventricular outflow obstructions and fibrosis of the conducting system.
