The cardiologist shows the film of an electrocardiogram of a patient with cardiac arrhythmia and bundle branch block. Heart and cardiovascular disease, cardiology and cardiography.
A 2:1 left bundle branch block is considered when complete left bundle branch block alternates with normal QRS complexes and the PR interval is fixed.
In complete left bundle branch block, the conduction of the LBB can be completely interrupted or can still be conducted, but it is delayed by at least 45ms than the RBB.
Electric impulses can be conducted, but the conduction speed slows down, resulting in conduction delay and affecting the morphology of the P wave, PR interval, and QRS wave.

When a 2:1 bundle branch block occurs, the refractory period of the bundle branch is longer than one basal cardiac cycle but shorter than two basal cardiac cycles.
Male, 13 years old, clinically diagnosed with secundum atrial septal defect. Note that the QRS wave in lead V1 of the electrocardiogram has a qR shape, indicating right ventricular hypertrophy.
The conduction system of the heart is supplied by the branches of the coronary artery. Once the blood vessels are blocked, it can cause conduction disorder. This picture is suitable for dark background. This picture is suitable for light background.
When there are more than 3 components in the QRS wave of lead V1, do not diagnose it as right bundle branch block, as this is a manifestation of fragmented QRS wave.
The AVN and His bundle form the conduction axis at the atrioventricular junction region. The His bundle is divided into three parts: non penetrating part, penetrating part, and bifurcation section.
On a conventional 12 lead electrocardiogram, the QRS wave of complete right bundle branch block in lead V1 is usually an rSR three-phase waveform.
In a wide QRS rhythm, the nature of the P wave can be observed in leads with lower QRS wave amplitudes. In this case, retrograde P waves can be seen in leads aVR and aVL.
