Masquerading and Left BBB: BBBB
Report:Atrial fibrillation with rapid ventricular response 150/min Right bundle branch block Left anterior hemiblock Left bundle branch block Bilateral bundle branch block. Nonspecific ST/T changes Comment:In this case one can diagnose BBBB directly
Gradual Completion of LBBB
Report: Sinus rhythm SVEBs Incomplete left bundle branch block Complete left bundle branch block, rate-dependent Comment: The tall monophasic R complexes in 1 and V6, with slightly delayed peak (late intrinsicoid of yore) and no preceding septal q wav
LBBB: Intermittent LAD
Report: Sinus rhythm SVEBs Left bundle branch block QRS 0.125â Intermittent left axis deviation â50o Comment: Approximately 50% of LBBBs have LAD; this one had LAD 50% of the time! How or why the predivisional LBBB becomes divisional, and back ag
Atypical LBBB: Anterolateral Q Waves
Report: Sinus rhythm SVEBs, runs of SVT Left axis deviation â50o Intraventricular conduction delay, probably atypical left bundle branch block Probable old anterior infarction ST/T changes suggest infarction/ischæmia. Comment: Post-arrest ECGs (a
LBBB with RAD: Acute Inferior Infarction
Report:Sinus rhythm 96-100/min Third degree AV block Junctional escape rhythm 45/min Left bundle branch block Right axis deviation +95o Acute inferior infarction Comment:Three contributors to heart failure are present in this trace: Acute infarction
LBBB with Transient Right Axis Deviation: Ischæmic Cardiomyopathy
Report: Sinus rhythm Right axis deviation (RAD) + 140o Left bundle branch block Comment: The unusual combination of LBBB and RAD is a surprisingly specific marker of congestive cardiomyopathy29. This patient had CABG following an inferolateral MI; subs
Supernormal Conduction in LBBB
Report:Atrial fibrillation with ventricular response 93/min Left bundle branch block, intermittent Supernormal conduction Probable LVH with ST/T changes (incomplete LBBB) Comment:The transition to narrow(er) QRS toward the end of the recording occurs
PAT with Block: LBBB RSR' in V1
Report:Atrial tachycardia 216/min with 2:1 block. LBBB. Comment:The only indisputable part of the computer and the Cardiologistâs reports is tachycardia. The tachycardia could not be sinus tachycardia even if there was a 1:1 conduction: the morpholog
Right, Left, then Right Bundle Branch Block
Report:Sinus tachycardia 140/min Second degree AV block First degree AV block in conducted beats PR 0.30â SVEBs, blocked (causing the pauses) Left bundle branch block Primary repolarisation changes c/c infarction/ischæmia Comment:This is an obvi
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. A sustained run could be mistaken for sinus bradycardia 50/min.
