Summary of "Interference dissociation during a baseline complete left bundle-branch block with advanced right bundle-branch block."

A 64-year-old woman presented to the hospital with a complaint of dyspnea on effort. The 12‑lead electrocardiogram showed a baseline complete left bundle-branch block, in which the right bundle developed >2:1 block. The subsequent blocked sinus impulse resulted in a ventricular pause that caused the ventricular escape presenting as a QRS complex with right bundle-branch block pattern. However, some of them disclosed typical fusion beats and led to interference dissociation. Although other possibilities including Lenegre's disease or myocardial disease were not excluded, the effective refractory period of both bundle branches degenerated by myocardial ischemia might be attributed to this rhythm.

Medical and Biotech [MESH] Definitions

Small band of specialized CARDIAC MUSCLE fibers that originates in the ATRIOVENTRICULAR NODE and extends into the membranous part of the interventricular septum. The bundle of His, consisting of the left and the right bundle branches, conducts the electrical impulses to the HEART VENTRICLES in generation of MYOCARDIAL CONTRACTION.

A form of heart block in which the electrical stimulation of HEART VENTRICLES is interrupted at either one of the branches of BUNDLE OF HIS thus preventing the simultaneous depolarization of the two ventricles.

Protein factors that inhibit the dissociation of GDP from GTP-BINDING PROTEINS.

Impaired or delayed impulse conduction between the right and left HEART ATRIA. Advanced interatrial blocks are often associated with arrhythmias (e.g., ATRIAL FLUTTER; and ATRIAL FIBRILLATION), direct conduction block via the Bachmann's bundle and concomitant left atrial enlargement. Syndrome of advanced interatrial block associated with SUPRAVENTRICULAR TACHYCARDIA is referred to as Bayes syndrome.

Bacteria that can survive and grow in the complete, or nearly complete absence of oxygen.
