Ventricular fibrillation:

1.Ventricular fibrillation irregular ventricular rate is 200-600 twitches/min.

2.The heart does not pump blood.

3.It leads to unconsciousness within 5 seconds.

4.The trigger is anoxia.

Atrioventricular block:

1.Atrioventricular block is the blockage of the conduction from the atria to the AV-node. Three degrees of AV block are known.

2.1st degree AV block: PQ - above 0.2 s

Atrioventricular block:

1.2nd degree AV blocksome of the P-waves are not followed by QRS-complexes

2.Mobitz type I - PQ-interval is increased progressively until a P-wave is not followed by a QRS-complex. (Wenchebach block).

3.Mobitz type II block - the ventricles drop some beats

Atrioventricular block:

1.3rd degree AV block (complete AV-block) is a total block of the conduction between the SN and the ventricles.

2.Atriums are regulated by SA node, ventricles by AV node
