In our recent clinical work, we have encountered several patients with “AV block”, but unfortunately, they know little about it. Therefore, today we will talk about AV block. As we have…
The most significant manifestation of first-degree AV block on the ECG is a PR interval of more than 210 ms. It has two prerequisites, one is in sinus rhythm, that…
Second-degree second-degree AV block is the most common type of second-degree AV block in clinical practice, and the life expectancy of patients with this type of block varies from person…
1. Causes (1) Congenital types: simple conduction abnormalities (without combined structural heart disease), structural heart abnormalities such as congenitally corrected transposition of great vessels, or maternal diseases such as systemic…
The sinus node is the “headquarters” of the human heartbeat, and it has a large fluctuation range, from 40-60 beats per minute when it is slow (e.g., during sleep) to…
Second degree atrioventricular block is divided into second degree I and second degree II. Second degree I is not serious if it occurs occasionally at night and there are no…
As we introduced earlier, the normal heartbeat is initiated by the sinus node, which is the “board of directors”, and then it is transmitted down the hierarchy to make the…
Second degree type II AV block is an abnormality in the conduction function of the heart that may have an impact on the patient’s life as the condition progresses. If…
Congenital complete atrioventricular conduction block (CCAVB) is a rare congenital arrhythmia with an incidence of approximately 1 in 22,000 [1] and a high early mortality rate, but if diagnosed early…
Stellate ganglion block is not a disease, but a treatment, a minimally invasive treatment commonly used in pain clinics. The general procedure is to inject local anesthetic drugs into the…
