First-Degree AV Block -ANSWER-Prolonged PR interval exceeding 200
ms with constant 1:1 AV conduction.
Mobitz I (Wenckebach) AV Block -ANSWER-Progressive PR prolongation
until a P wave is blocked and a QRS is dropped.
Mobitz II AV Block -ANSWER-Constant PR interval with intermittent
non-conducted P waves, high risk of progression to complete block.
Third-Degree AV Block -ANSWER-Complete AV dissociation with
independent atrial and ventricular rates and narrow or wide escape.
High-Grade AV Block -ANSWER-Consecutive P waves blocked (2:1 or
greater) with otherwise normal or constant PR intervals.
Right Bundle Branch Block (RBBB) -ANSWER-QRS > 120 ms, rSR' pattern
in V1-V3, and slurred S wave in I and V6.
, Left Bundle Branch Block (LBBB) -ANSWER-QRS > 120 ms, broad
notched or slurred R wave in I, aVL, V5-V6, and deep S in V1.
Left Anterior Fascicular Block (LAFB) -ANSWER-Left axis deviation (-45
to -90 degrees), qR in I and aVL, and rS in II, III, aVF.
Left Posterior Fascicular Block (LPFB) -ANSWER-Right axis deviation (>
+90 degrees), rS in I and aVL, and qR in II, III, aVF.
AV Dissociation -ANSWER-Independent atrial and ventricular rhythms,
often due to enhanced subsidiary pacemakers or complete block.
Incomplete RBBB -ANSWER-RSR' pattern in V1 with QRS duration
between 100 and 119 ms.
Incomplete LBBB -ANSWER-Narrower LBBB morphology with QRS 100-
119 ms and loss of septal Q waves in lateral leads.
Failure to Capture -ANSWER-Pacemaker spikes present without
subsequent P waves or QRS complexes.
Failure to Sense (Undersensing) -ANSWER-Pacemaker fails to recognize
native cardiac activity, pacing asynchronously inappropriately.
