网页2019年10月19日 · Third-degree AV block indicates a complete loss of communication between the atria and the ventricles. Without appropriate conduction through the AV node, the SA node cannot act to control the heart rate, and cardiac output can diminish secondary to loss of coordination of the atria and the ventricles.
Identifying and Treating Third-Degree AV Block (Complete Heart Block)
网页A third-degree atrioventricular (AV) block, also known as a complete heart block, occurs when there is a communication failure in the heart between the atria and ventricles. Often, a third-degree AV block develops due to a gradual deterioration of a second-degree AV block (type I or type II).
