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 there is a the first degree interatrial block, the impulse from the right atrium is slowly transmitted to the left atrium, causing widening notched P wave.
The transverse vectorcardiogram generates a chest leads electrocardiogram, with the maximum ventricular excitation potential oriented towards the left posterior region.
Under normal circumstances, in the chest lead electrocardiogram, the amplitude of the R wave gradually increases from lead V1 to lead V6.
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.
In the aVR lead, the QRS wave can be in the form of QS, rS, Qr, rsr, etc., with the main wave being 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.
Ventricular tachycardia originating from the right ventricular outflow tract can be sustained or short-burst, and is a benign idiopathic ventricular tachycardia.
When Bachmann bundle conduction is interrupted, the right atrium excites the left atrium through the coronary sinus, producing positive and negative biphasic P-waves in the inferior leads.
When Bachmann bundle conduction is interrupted, the right atrium excites the left atrium through the coronary sinus, producing positive and negative biphasic P-waves in the inferior leads.
The high lateral lead group includes leads I and aVL, used to explore the myocardium of the high lateralwall of the left ventricle.
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.
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.
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.
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.
Under normal circumstances, notch T waves are more common in leads V2-V3 and are caused by asynchronous local ventricular repolarization.
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.
In the frontal plane lead system, when the maximum QRS wave potential is more parallel to a certain lead, the R wave amplitude of that lead is highest in the limb 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.
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.
Sometimes, left ventricular hypertrophy with tall T waves is easily misdiagnosed as hyperkalemia and hyperacute T waves, and ECG needs to be carefully identified in combination with clinic.

In the frontal lead system, the lead axes of the 6 limb leads form a hexaxial reference system, which is one of the important theories of electrocardiography.
