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.
During left posterior fascicular block, the ECG showed right axis deviation. The QRS wave in leads I and aVL was rS wave, and the duration of QRS wave was less than 120 ms.

When the left free wall and septal accessory pathway are excited, preexcitation waves with different polarities are generated in leads  and aVL.
Due to the large mass of the left ventricle, the dominant excitation potentials of the left and right ventricles are oriented towards the left ventricle, i.e. towards the left, Inferior and posterior.
The transverse vectorcardiogram generates a chest leads electrocardiogram, with the maximum ventricular excitation potential oriented towards the left posterior region.
The terminal excitation of the ventricle forms the final part of the S wave in lead V1, gradually returning to the isoelectric line, and forms a small S wave in lead V5.
In humans, Purkinje fibers are not distributed throughout the entire ventricular wall, but rather in the superficial myocardium beneath the endocardium and do not reach the epicardium.
When the left anterior wall and posterior wall accessory pathway are excited, preexcitation waves with different polarities are generated in the inferior wall leads of ,  and aVF.
When the first degree interatrial block occurs, the conduction time from the right atrium to the left atrium is prolonged, the P wave widens, and bimodal P wave ECG changes appear.
Abnormal ECG refers to changes in depolarization waves and or repolarization waves, most of which are pathologic and few are physiological.
On the electrocardiogram, observing the morphology of QRS waves in lead V1 can distinguish whether ventricular pre excitation is located in the left ventricle or the right ventricle.
The initial excitation of the ventricle forms a small r wave in lead V1 and a small q wave in lead V6.
Surrounding the atrioventricular ring, except for the anterior septum of the left ventricle, there is no distribution of accessory pathways, and accessory pathways can exist in other parts.
When there is a left ventricular free wall bypass,  the polarity of  the ventricular preexcitation is positive in lead V1 and negative in lead aVL on the electrocardiogram.
Sometimes, there may be slight non-specific changes and normal variations in the electrocardiogram, which are often due to physiological reasons and have no clinical therapeutic significance.
Abnormal ECG refers to changes in depolarization waves and or repolarization waves, most of which are pathologic and few are physiological.
On the electrocardiogram, observing the morphology of QRS waves in lead V1 can distinguish whether ventricular pre excitation is located in the left ventricle or the right ventricle.
During normal ventricular excitation, the earliest epicardial breakthrough point is located in the paraventricular septal area, and the RV outflow tract and the base of the LV are finally excited.
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.
The conduction in ventricle is mainly divided into right bundle branch and left bundle branch. The left bundle branch includes left anterior fascicle and left posterior fascicle.
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.
The His bundle and the proximal bundle branches are mainly supplied by the 1st septal branch of the left anterior descending branch and the atrioventricular node artery of the right coronary artery.
