Spurious ST Segment Elevation
Report: Sinus bradycardia 43/min Left atrial abnormality First degree AV block Escape-capture bigeminy Third degree AV block (mid-second strip onward) Junctional rhythm 64/min Comment: The broad shallow sinus P waves, with their first degree AV bl
Wenckebach Conduction of Sinus Tachycardia
Report: Sinus tachycardia 116/min SVEB Second degree AV block, Möbitz 1 Comment: Some of the blocked P waves look different in shape from others, due to their position on the preceding T wave. Their timing easily distinguishes them from blocked SVEBs.
Complete Heart Block: Anterior MI
Report: Sinus tachycardia Third degree AV block Ventricular escape beats and rhythm Comment: The slowing of the sinus rate in the forth and fifth strips was ominous, reflecting sinus node hypoxia or ischæmia. The ventricular escapes were slow and unr
Advanced 2o AV Block
Report: Sinus rhythm Progressive first degree AV block (top) VEBs Advanced second degree AV block Comment: The 14 second pause follows the VEB, but the ground had been set even before the first VEB: a single blocked P wave is seen at the end of the to
Bilateral Bundle Branch Block (BBBB)

PAT with Block: Pacemaker Lead
Report:Atrial tachycardia 138/min Second degree AV block, Möbitz 1; 2:1 & 3:2 block Right atrial electrode recording (bottom strips) Comment:The question is a "trick" one, designed to implicate the spurious change in the heart rate in the patient's pr
