What does intermittent complete right bundle branch block mean?

Intermittent complete right bundle branch block usually refers to a specific manifestation of abnormal electrocardiogram (ECG). The details are as follows:

The human heart normally generates electrical impulses from the sinoatrial node, which then travel through conduction tissues to the atrioventricular junction and left atrium, coordinating cardiac contraction. When impulse conduction is delayed or completely interrupted, it is called a conduction block. The right bundle branch is part of the intraventricular conduction system; when a patient experiences complete interruption of conduction in this pathway, it is known as complete right bundle branch block. If this condition occurs intermittently, it is termed intermittent complete right bundle branch block. The right bundle branch is one of the key pathways for conduction in the right ventricle, and any disruption may lead to abnormal timing between contractions of the left and right ventricles. As the condition progresses, it may result in arrhythmias, heart failure, and symptoms such as chest tightness and palpitations.

If patients experience any discomfort, they should promptly seek medical attention. It is important to maintain a positive mental state and avoid emotional excitement. Maintain regular作息 (daily routines) and avoid excessive fatigue.
