What is a Wenckebach AV block?
a. a delay in the conduction of the impulse through the AV junction
b. increasingly difficult AV node conduction showing a P wave not followed by a QRS complex on ECG
c. a delayed AV conduction at the bundle braches
d. no conduction if impulse from the atria to the ventricles
Answer: b. increasingly difficult AV node conduction showing a P wave not followed by a QRS complex on ECG
A wenckebach AV block, also called a Mobitz I block, is when increasingly difficult AV node conduction shows a P wave not followed by a QRS complex on ECG. this is considered a second-degree AV block.
