Alternating LBBB with Right Axis Deviation
Report:Sinus rhythm 93/min Alternating complete & incomplete left bundle branch block Axis +95o with complete LBBB Indeterminate axis with incomplete LBBB Comment:The basic LBBB morphology is, as always, best seen in lead V1. In the limb leads, both c
Large Right Precordial R Waves in LBBB
Report:Sinus tachycardia 120/min Left atrial abnormality (LAA) Left bundle branch block Probable old anterior infarction Comment:The right precordial are waves look typically thin, like antennæ or unipolar pacing spikes. There is also a loss of R am
Bilateral Bundle Branch Block (BBBB)
Report: Sinus tachycardia 110/min Left atrial abnormality (LAA) Right axis deviation (RAD) +120o Probable left posterior hemiblock Right bundle branch block ST/T changes consistent with infarction/ischaemia Comment: Three years previously, this pati
Ventricular Fusion Beats
Report: Sinus rhythm First degree AV block PR 0.28” VEBs, possible parasystole Ventricular fusion beats Left bundle branch block QRS 0.20” Comment: The criteria for diagnosing ventricular fusion beats were formulated by Marriott et al18 in 1962:
Bilateral Bundle Branch Block
Report:Sinus tachycardia 113/min Left anterior hemiblock Right bundle branch block Comment:This is only a bifascicular block – complete right and partial left bundle branch block. The term BBBB is not usually used for this. But if, as here, the patient
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 0.125” Intermittent left axis deviation –50o 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 again,
Atypical LBBB: Anterolateral Q Waves
Report: Sinus rhythm SVEBs, runs of SVT Left axis deviation –50o Intraventricular conduction delay, probably atypical left bundle branch block Probable old anterior infarction ST/T changes suggest infarction/ischæmia. Comment: Post-arrest ECGs (and
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
