Right bundle branch block includes both complete and incomplete types, the former may have heart rate slowing, the latter usually does not cause heart rate slowing.
Right bundle branch block is a common type of arrhythmia and can be categorized into two main types, complete right bundle branch block and incomplete right bundle branch block, based on whether the time limit of the QRS wave cluster is ≥0.12s. It is characterized by rapid excitation of the left ventricle through the Purkinje fibers, followed by slow conduction of excitation of the right ventricle through the ventricular myocardium.
Patients with incomplete right bundle branch block usually have no clinical symptoms and their heart rate does not slow down, but patients with complete right bundle branch block often have symptoms such as dizziness, chest tightness, and fatigue, which are often accompanied by a slowing of the heart rate.
When right bundle branch block occurs, it is recommended to consult a doctor in time, improve the cardiac ultrasound, 24-hour dynamic electrocardiogram and other related examinations, and formulate a reasonable treatment plan as appropriate.
