Atrioventricular block - Wikipedia
Atrioventricular block (AV block) is a type of heart block that occurs when the electrical signal traveling from the atria, or the upper chambers of the heart, to ventricles, or the lower chambers of the heart, is impaired.

2024年4月14日 · Your heart may beat slowly or skip beats. In severe cases, heart block can affect your heart’s ability to pump blood, causing low blood flow to your entire body. People are more likely to acquire heart block later in life than to have it at birth. Other names for heart block are atrioventricular (AV) block or a conduction disorder.

2023年2月3日 · AV (Atrioventricular) Heart Blocks: AV heart blocks occur when the electrical signals that control the heart’s rhythm are delayed or prevented from reaching the ventricles.
Atrioventricular Block > Fact Sheets > Yale Medicine
Atrioventricular block is a heart rhythm disorder that causes the heart to beat more slowly than it should. It’s caused by communication problems within the heart’s electrical conduction system. For some people, the condition doesn’t cause symptoms; for others, it may be life-threatening.

Atrioventricular block - Symptoms, diagnosis and treatment
2023年1月25日 · Atrioventricular (AV) block is a cardiac electrical disorder defined as impaired (delayed or absent) conduction from the atria to the ventricles. The severity of the conduction abnormality is described in degrees: first-degree; second-degree, type I (Wenckebach or Mobitz I) or type II (Mobitz II); and third-degree (complete) AV block.

Mobitz type I second-degree AV block may be physiologic in younger and more athletic patients. If the QRS complex is narrow, Mobitz type I second-degree AV block is nearly always in the AV node; if the QRS complex is wide (> 0.12 second), Mobitz I second-degree AV block is more likely to be in the His-Purkinje system (60 to 70%) than in the AV node (30 to 40%) (2).
