1 st degree AV block 2 nd degree AV block 3 rd degree AV block The atrioventricular (AV) conduction system and AV blocks The AV system consists of the atrioventricular node (AV node) and the His-Purkinje system. These structures conduct the atrial impulse to the ventricles. Impulse conduction through the atrioventricular node is slow.

1 st degree heart block 1st degree block indicates slowed transmission of electrical activity through the AV node - therefore giving a prolonged PR interval. It can be a normal variant. 2 nd degree heart block There are two varieties of 2nd degree heart block to be aware of: Mobitz type 1 (Wenckebach)

Full-featured ECG functional block diagram. Features Understanding the required electronic components for an ECG is easier if it is separated into the analog front-end (AFE), which digitizes these signals, and "the rest of the system," which analyzes, displays, stores and transmits the data.

The delay between activation of the RV and LV produces the characteristic "M-shaped" R wave seen in lateral leads. Delayed overall conduction time to the LV extends the QRS duration to ≥ 120 ms. Sequence of conduction in LBBB: 1) Conduction delay means impulses travel first via the right bundle branch (black arrow) 2) Septum is activated.

This chapter discusses third-degree AV block, which is synonymous with AV dissociation, complete AV block, AV block III and AV block 3. In third-degree AV block, no atrial impulses are conducted to the ventricles. The atria and the ventricles are electrically dissociated from each other. This condition is referred to as atrioventricular (AV.

The electrocardiogram (ECG) records from the body surface and registers the differences in electrical potential generated by the heart. The signal recorded is determined by action potentials generated by millions of individual cells and their sequence of activation. A multitude of factors, both cardiac and extracardiac, alter the final electrical signal. For instance, the electrical forces.

Many of the ECG rhythm strips come from the collection of the late Dr. Alan Lindsay, master teacher of electrocardiography. Most of the 12- and 6-lead ECGs were recorded at LDS Hospital in Salt Lake City, Utah. Marquette Electronics has also given permission to use ECG rhythms and diagrams from their educational posters.

The ECG demonstrates complete AV dissociation, with independent atrial and ventricular rates. Complete heart block: There is AV dissociation, with the atrial rate (~100 bpm) independent of the ventricular rate (~40 bpm) In complete heart block, there is complete absence of AV conduction, with none of the supraventricular impulses conducted to.
