Description

Second Degree AV Block Type I aka Mobitz I / Wenckebach 

 • Normal P waves.

 • The PRI progressively lengthens until a P wave is not followed by a QRS.

 • As the PRI lengthens, there is shortening of the RR interval.

 • The RR interval containing the dropped P wave is less than 2x of the shortest RR interval.

 • The PRI (may be normal or prolonged) of the first conducted P wave is shorter than the last conducted PRI.

 • The largest increment in the PRI is usually on the second conducted P wave.

 • There is "group-beating" on the ECG.
