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.
In the frontal plane lead system, when the initial vector of the QRS wave is directed downward, the positive initial QRS wave is recorded in leads II, III, and aVF.
In the spatial anatomy of the heart, the axis from the base of the heart to the apex of the heart is called the long axis, that is, the upper right side faces the lower left side.
Clockwise rotation electrocardiogram refers to the transition of the rS waveform of the chest lead to the left chest lead, with the transition lead exceeding the V4 lead.
Septal q wave loss refers to the initial q wave loss of leads I, aVL, V5, and V6, which can be partially or completely lost.
Clockwise and counterclockwise rotation are common electrocardiographic phenomena, mainly used to describe the evolution of R-wave amplitude in chest leads.
In the frontal lead system, when the initial vector of the QRS wave points upward, the II, III, and aVF leads record a negative initial QRS wave, i.e., a small q wave.
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.
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.
It is best to measure the QRS wave duration in a 12 lead synchronous electrocardiogram, as some of the QRS wave start and end points are located on the isoelectric line.
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.
The transverse vectorcardiogram generates a chest leads electrocardiogram, with the maximum ventricular excitation potential oriented towards the left posterior region.
On the conventional 12-lead ECG, under normal circumstances, there are some inherent patterns of QRS waves in different leads, which are not exactly the same.
Under normal circumstances, in the chest lead electrocardiogram, the amplitude of the R wave gradually increases from lead V1 to lead V6.
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.
QRS wave is a ECG wave generated by ventricular excitation, typically in a three-phase waveform, named qRs wave. The QRS waveform of each lead is different.

Abnormal ECG refers to changes in depolarization waves and or repolarization waves, most of which are pathologic and few are physiological.
The initial excitation of the ventricle forms a small r wave in lead V1 and a small q wave in lead V6.
QRS wave is a ECG wave generated by ventricular excitation, typically in a three-phase waveform, named qRs wave. The QRS waveform of each lead is different.
The accompanying ST-T changing in the context of wide QRS complexes.The wide QRS complex changes the order of ventricular depolarization and secondary changes in the order of repolarization.
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.
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.
The high lateral lead group includes leads I and aVL, used to explore the myocardium of the high lateralwall of the left 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.
Narrow QRS wave and wide QRS wave
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.
During ventricular depolarization, a spatial QRS loop is generated, projected onto the frontal lead system, forming the frontal QRS loop, which further forms the electrocardiogram.
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.
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.
At present, the definition of narrow QRS complex is QRS durationgreater than or equal to 120ms, and wide QRS complex is defined as QRS duration beyond 120ms.
