1st degree heart block. Ralston et al, 2006. Teacher’s guide: A. Prolonged PR of 8 mm (320 ms), no dropped QRSs -> 1st degree. B. Progressive prolongation of PR until 4th P wave is not followed by a QRS (ie: 3rd and 7th QRSs are dropped in figure above) -> 2nd degree Mobitz type I .

1st degree heart block Like Sinus Rhythm except long PR interval > .20 sec. interval Mobitz I (Wenckebach) gets longer and longer until there is a P wave without a QRS complex (dropped QRS. Pattern repeats itself. P waves fall on time. QRS
