A review of the EKG diagnosis of atrioventricular block, including discussion of the 3 different degrees of block, including the 3 different types of 2nd deg
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.
This manifests on the ECG as gradual increase of PR interval before a block occurs. The ECG criteria for a second-degree AV block (Mobitz type I or Wenkebach) is discussed with 12-lead ECG examples. Second-Degree Atrioventricular (AV) Block Type I (Wenkebach) ECG Review - Criteria 2:1 atrioventricular block is a form of second-degree AV nodal block and occurs when every other P wave is not conducted through the AV node to get to the ventricles, and thus every other P wave Heart block is a problem with the heart's electrical system that causes your heart to beat too slowly (bradycardia). The condition is also called atrioventricular (AV) block. The AV node is a cluster of cells that connects the electrical activity in the top chambers of the heart (atria) to the bottom chambers of the heart (ventricles). The ECG criteria for a second-degree AV block type II (Mobitz type II) is discussed with 12-lead ECG examples.
2015-07-14 EKG change: 1st deg Heart block-mild form of electrical conduction delay from atrial to the ventricles Sinus tachycardia-fast heart rate (>100/min) in normal (sinus) rhythm Biatrial enlargement- Bigger than expected, of upper two chambers, each one called atrium) Rightward axis- the net electrical force of the heart directed toward right, normally its to the left.

3rd Degree AV Block The 3rd Degree AV Block is often referred to as a complete heart block because there is no communication or association of the atria and ventricles. Each has its own pacemaker working independently.
Om blockeringen sitter på den vänstra grenen kommer det bli ett litet ”jack” på toppen av QRS-komplexet (ledning V5). 2015-07-07 INSTRUKTION: Klicka på de röda länkarna nedan för att visa EKG-remsorna (öppnas i ett nytt fönster). ATRIO-VENTRIKULÄRA BLOCK AV-block I Kännetecknande för AV-block I är att överledningstiden mellan förmak och kammare är förlängd (PQ-tid > 0,22 sek). Alla P-vågor följs av QRS-komplex. AV-block I- Sinusrytm, PQ-tid 0,26 s- Vänsterställd elaxel- Pappershastighet 50 mm/sekOBS The 3rd Degree AV Block is often referred to as a complete heart block because there is no communication or association of the atria and ventricles. Each has its own pacemaker working independently. Note how inconsistent the 'PRI' lengths are!
