Those with complete right bundle branch block also do not necessarily have extensive myocardial damage and are often not significant if not accompanied by other organic heart conditions. However, if there are other concomitant conditions, consult a cardiologist. Drug treatment: generally ineffective. 1.Treatment of primary disease Those with acute myocardial ischemia in coronary artery disease should improve the myocardial blood supply status as soon as possible, and discontinue all drugs that may aggravate conduction block if caused by drugs. Treatment of comorbidities If there is heart failure, treat according to heart failure; if there are other arrhythmias, treat according to arrhythmia chapter. 3. Placement of artificial pacemakers A permanent pacemaker should be considered for those with double bundle branch block or more and a history of cardiogenic cerebral insufficiency. Patients with chronic bundle branch block do not require treatment if they are asymptomatic. Bifurcation and incomplete trifurcation blocks may progress to complete atrioventricular block, but whether and when this will occur is unpredictable and prophylactic pacemaker therapy is not routinely indicated. In acute anterior wall myocardial infarction with double or triple branch block, or chronic double or triple branch block with Adams-Stokes syndrome, early pacemaker therapy should be considered. Patients with chronic bundle branch block who are asymptomatic do not need to receive treatment. Pacemaker therapy should be considered early in patients with acute anterior wall myocardial infarction with double or triple male branch block or chronic double or triple branch block with the development of Adams-Stokes syndrome. Patients with intraventricular conduction block and heart failure may be considered for cardiac resynchronization devices, depending on the indication for surgery.
