Second Degree AV Block Type I Mobitz I
increased Pr interval until no P wave can be seen
next P wave has shorter pr interval

Third degree heart block
no p waves

2nd degree mobitz type 2 heart block sign is
sudden non-conducted P waves with no change in PR intervals

first degree hear block
prolonged PR interval
What defines the PR interval?

The P waves are completely dissociated from the QRS complexes. The QRS complexes are narrow, indicating a ______ rhythm

Third degree AV block
junctional escape rhytm

In atrial fibrillation, however, the P waves, which represent depolarization of the atria, are absent

right bundle branch block
greatly prolonged QRS complex

Left bundle branch block
there is a QRS width greater than 0.12 sec. This indicates a bundle branch block. There is also a left axis deviation, which is consistent with a left bundle branch block.

atrial flutter

left bundle branch block
prolonged qrs
left axis deviation (lead III)
