Right bundle branch conduction block is divided into complete right bundle branch conduction block and incomplete right bundle branch conduction block according to the degree of block. Complete right bundle branch block means that the right bundle branch that transmits to the right ventricle is faulty and the bioelectrical signal cannot be transmitted directly to the right ventricle, but it does not matter, the electrical signal can be transmitted from the left ventricle, only the contraction of the right ventricle is slightly delayed. Complete right bundle branch block does not necessarily have extensive myocardial damage, and is often not significant if it is not associated with other organic heart disease. If you have no organic heart disease on further medical examination, incomplete right bundle branch block is usually of no pathologic significance. Since there is no pathological significance, i.e. a normal healthy lifestyle will not have an effect on it. Its diagnosis can be based on the following findings: 1. Electrocardiogram The heart is excited by the pacing point, atria and ventricles successively in each cardiac cycle, accompanied by bioelectric changes, and the graph of various forms of potential changes elicited from the body surface by electrocardiographic tracers is called electrocardiogram (ECG for short). ECG is an objective indicator of the process of occurrence, propagation and recovery of cardiac excitation. ECG is an important tool to help determine whether the electrical activity of the heart is normal or not, and it is the earliest, most common and basic diagnostic method in the diagnosis of coronary heart disease. 2, dynamic ECG Dynamic ECG is a method that can continuously record and compile and analyze the changes of ECG of heart in active and quiet state for a long time. It is also called Holter monitoring. Dynamic electrocardiogram (DCG) can record all abnormal waves and detect all kinds of arrhythmias and asymptomatic myocardial ischemia in various states within 24h, which provides accurate and reliable basis for the diagnosis of various heart diseases. In clinical application, it has a high detection rate especially for early coronary artery disease. 3.Doppler echocardiography There are many red blood cells within the blood, which can reflect and scatter ultrasound and can be considered as a tiny source of sound. The probe is placed in the rib cage without moving and emits ultrasound. When red blood cells flow in the heart or large blood vessels, the sound frequency scattered by the red blood cells changes. As the red blood cells move toward the probe, the reflected sound frequency increases, and vice versa, decreases. This difference in sound frequency between the red blood cells and the probe in relative motion is called the Doppler shift. It shows the speed and direction of blood flow and the nature of the blood flow. Doppler echocardiography is divided into pulsed Doppler echocardiography, continuous wave Doppler echocardiography, and color Doppler echocardiography. The most commonly used is pulsed Doppler echocardiography, which provides a real-time Doppler spectrogram of blood flow at any point in the heart with two-dimensional image monitoring and positioning.
