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.
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.
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.
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.
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.
Narrow QRS wave and wide QRS wave
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.
On the screen of a modern ultrasound scanner, the image of the right ventricular outflow tract with Doppler mapping in blue.
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.

The QT interval of ECG is from the beginning of QRS wave to the end of T wave, representing the total time of ventricular depolarization and repolarization.

The illustration shows the two patterns of ventricular tachycardia episodes.The green circle represents sinus rhythm. Picture A shows paroxysmal episodes of ventricular tachycardia, and picture B shows short bursts.
R wave greater than S wave is judged to be positive; R smaller than S is judged to be negative; R equal to S amplitude is judged to be equipotential.

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.
Male, 84 years old, admitted to hospital with chest pain for 1 day. ECG showed acute inferior and posterior MI and possibly right MI. The patient died of ventricular fibrillation the next day.
Male, 84 years old, admitted to hospital with chest pain for 1 day. These ECG rhythms are the Holter monitor records of the patients after admission, and they are third degree atrioventricular block.
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.
Four anatomical malformations of tetralogy of Fallot: 1 aortic straddling; 2 ventricular septal defect; 3 right ventricular hypertrophy and 4 pulmonary artery stenosis.
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.
Idiopathic ventricular tachycardia originating from the right ventricular outflow tract forms a high amplitude R wave in the inferior leads and a QS wave or rS wave in the V1 lead.
Idiopathic ventricular tachycardia originating from the right ventricular outflow tract is a benign ventricular tachycardia. This ECG shows a short burst pattern of ventricular tachycardia.
When the frontal QRS axis is at +83, the R amplitude of lead aVF is the highest.The frontal QRS axis is almost perpendicular to the axis of lead .
The initial excitation of the ventricle forms a small r wave in lead V1 and a small q wave in lead V6.
Idiopathic ventricular tachycardia originating from the right ventricular outflow tract is a benign ventricular tachycardia. This ECG shows a short burst pattern of ventricular tachycardia.
Ventricular tachycardia originating from the right ventricular outflow tract can be sustained or short-burst, and is a benign idiopathic ventricular tachycardia.
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.
When the frontal QRS axis is at +57, the QRS amplitude of lead is the highest.The frontal electrical axis is almost perpendicular to aVL lead, so the algebraic sum of QRS amplitude is almost zero.
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.
The high lateral lead group includes leads I and aVL, used to explore the myocardium of the high lateralwall of the left ventricle.
Heart rate on paper for recording an electrocardiogram, prevention of heart diseases. Electrocardiogram strips with cardiac arrhythmias. Alterations of heartbeats represented on paper. Copy space.
Idiopathic ventricular tachycardia originating from the right ventricular outflow tract is a benign ventricular tachycardia. This ECG shows a short burst pattern of ventricular tachycardia.
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.
In frontal lead system, when the average ventricular excitation potential is in the range of +60 degrees to+90 degrees, the QRS main wave of aVL lead is negative.
Idiopathic ventricular tachycardia originating from the right ventricular outflow tract is a benign ventricular tachycardia. This ECG shows a short burst pattern of ventricular tachycardia.
If the electrocardiogram during the onset of ventricular tachycardia cannot be recorded, it is possible to incorrectly analyze the QRS waveform based on the QRS waveform during the attack.
