Sudden Ventricular Standstill
Report: Sinus tachycardia 100/min Borderline first degree AV block Left bundle branch block Third degree AV block Ventricular escape beats (bottom) Comment: This is a typical example of AV block in acute anterior infarction: RBBB or LBBB (as here) fo
SVEBs in Bigeminy or 2:1 AV Block?
Report: Sinus rhythm 72/min Second degree AV block, 2:1 Ventriculophasic sinus arrhythmia Left bundle branch block Comment: The ventriculophasic effect is so marked that one cannot be completely certain that the atrial complexes at the end of T wave
Bilateral Bundle Branch Block (BBBB)
Report:Sinus rhythm 94/min Advanced (4:1) AV block Left bundle branch block Comment:While it is possible that there exist independent AV nodal block and isolated LBB disease, the block as recorded is more likely an expression of BBBB, viz. permanent
Aberrant Reentry Beats of Junctional Origin
Report: Sinus bradycardia 36/min (middle & end of bottom strip) Sinus arrest, possibly exit block Junctional escape rhythm Reentry (echo) beats of junctional origin Retrograde first degree VA block 0.26â Antegrade first degree AV block 0.26â Lef
Dig the Break!
Report: Sinus rhythm 96/min Second degree AV block, 2:1[!xe "AV block:concealed:dig the break" \b!] SVEB[!xe "SVEBs:unmasking 2o AV block" \b!] Left bundle branch block Comment: The blocked alternate P waves are almost completely hidden by the descend
Xylocaine & BBBB
Report:Atrial tachycardia, possibly sinus, 174/min 2:1 AV block Left bundle branch block Period of 1:1 conduction Comment:The exact doubling and then halving of the ventricular rate should have steered the CCU staff away from xylocaine. Broad complex
Rate-Dependent LBBB
Report: Sinus rhythm 90/min SVEBs, blocked, in bigeminy Left bundle branch block, rate-dependent Comment: The blocked atrial extrasystoles are discretely etched on the onset of the T wave. In the upper strip, the last LBBB complex has a distinctive nip
Xylocaine Reflex
Report: Top & middle: Atrial fibrillation Rate-dependent left bundle branch block VEB Bottom: Sinus rhythm SVEBs with LBBB aberration Comment: This is a fine example of xylocaine reflex, compounded by two 200 Joule shocks! There was no need for it:
Killip-Gault Rule and Exception
Report: Sinus rhythm and arrhythmia SVEBs 9 beat run of (probable) atrial fibrillation Rate-dependent bundle branch block, probably LBBB Comment: This is Lead 2 and one cannot tell with certainty that the IVCD is, specifically, LBBB. It looks like it,
VEB: the Compensatory Pause
Report:Sinus rhythm 62/min First degree AV block (PR 0.22â) VEB Left bundle branch block Comment:The P waves are sharply etched in V1 and the one blocked by the VEB is seen quite clearly. There is no need to measure the compensatory pause containing
