charcot_bouchardNo. No guys. Bundle of his located below AV node and it can generate impulse. it calls junction escape rhythm and narrow complex. Below this is purkinje, bundle branch & ventricular muscle. those are wide complex+32019-08-02T19:49:56Z
The atria and ventricles beat independently of each other. P waves
and QRS complexes not rhythmically associated. Atrial rate >
ventricular rate. Usually treated with pacemaker. Can be caused

yotsubatoanswer was ablation near the AV node.
No it wasnt. It was ablation OF THE AV node itself. Which faked me out. +52019-06-16T12:19:52Z
makinallkindzofgainzThe tangent by user "brbwhat" says that there is "pr lengthening progressively" but there is not.
This is 3rd degree AV block. The P waves march out consistently at their own rate, and the QRS complexes march out at their own rate. There is complete dissociation between the P waves and QRS complexes. They have no relationship. This is exactly what you would see if you ablated the AV node. The SA node would continue to to create P waves. The bundle of His would continue to generate junctional (normal looking) QRS complexes.+22020-02-01T00:48:57Z
brbwhatHad the same doubt, Read the part again and found this.
Type 2 Is caused when purkinje is hanging by a thread and therefore some impulses conducted, some not.
Chb is caused by purkinje not conducting impulses from san, some lower pacemaker ie purkinje or his is depolarising by itself hence venrticles beat independently. There is BLOCK in purkinje for conduction from san.
Among options the only thing that establishes this block is avn ablation.+2020-01-31T21:17:25Z
