2024年5月31日 · There are four main types of heart blocks, each with unique characteristics and effects on the heart’s rhythm. First-degree heart block is the mildest form, characterized by a prolonged PR interval of more than .20 seconds (>200 milliseconds) on the electrocardiogram (ECG) but without missed beats.

2021年11月8日 · This page provides an introduction to Heart Block rhythms with links to our lessons and drills. Heart block rhythms occur when the cardiac electric impulse is delayed or blocked within the AV node, bundle of His or the Purkinje system.

2020年7月3日 · In this article, we'll explain everything you need to know about atrioventricular (AV) blocks, including a 1st degree AV block, 2nd degree AV block type 1 (Mobitz I or Wenckebach), 2nd degree AV block type 2 (Mobitz II), and the 3rd degree AV block.

2024年4月14日 · A provider may find first-degree heart block during a routine electrocardiogram (EKG). Symptoms of third-degree heart block are more intense due to the slow heart rate.

2020年11月3日 · Heart Block and Conduction Abnormalities with first, second, third degree blocks; and fascicular blocks

Heart block can occur anywhere in the specialized conduction system beginning with the sino-atrial connections, the AV junction, the bundle branches and their fascicles, and ending in the distal ventricular Purkinje fibers.
