In the lower tracing (lead II), P1 is conducted. P2 is blocked; in other words, this patient's AV node cannot conduct at the R1P2 interval. P3 was going to be conducted. How do I know that? This ...
Some consider 2:1 AV block to be type II block, claiming that the PR interval doesn't lengthen. What they don't realize is that determining whether the PR interval lengthens requires at least 2 ...
A first-degree AV node block occurs when conduction through the AV node is slowed, thus delaying the time it takes for the action potential to travel from the SA node, through the AV node, and to the ...
In second-degree AV nodal block (a.k.a. Wenckebach block or Mobitz Type I AV block), varying failure of conduction through the AV node occurs such that some P waves may not be followed by a QRS ...
