Masquerading Bundle Branch Block
Report:Atrial fibrillation with ventricular response 80-120/min 1 Fixed-rate ventricular pacemaker rhythm 50/min 2 Fusion beat (third paced complex) 1 R-on-T pacing 1 Right bundle branch block 1 Left anterior hemiblock 1 Standard masquerading bundl
Old Anteroseptal MI & BBBB
Report:Atrial fibrillation with rapid response 160/mi9n Right bundle branch block Left anterior hemiblock Standard masquerading bundle branch block Old anteroseptal infarction Comment:In 1 and aVL the QRS resembles LBBB rather than RBBB, a situation
Incongruous BBBB
Report: Sinus rhythm 84 â 88/min Advanced second degree AV block 3:1 & 4:1 AV block Right bundle branch block PR interval 0.32â Left bundle branch block PR interval 0.20â Comment: This is quite rare. The two bundle branch blocks have differen
Alternating RBBB & LBBB?
Report: Sinus rhythm Second degree 2:1 AV block Alternating RBBB & LBBB Discordant PR intervals Left axis deviation -35o (in RBBB) Non-specific ST/T changes (during RBBB) Or: Conducted RBBB with 2:1 and advanced 2o AVB Ventricular escape beats Es
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
Bilateral Bundle Branch Block
Report:Sinus tachycardia 113/min Left anterior hemiblock Right bundle branch block Comment:This is only a bifascicular block â complete right and partial left bundle branch block. The term BBBB is not usually used for this. But if, as here, the patie
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
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
3:2 Möbitz 2 AV Block
Report: Sinus tachycardia 106/min Left atrial abnormality (LAA) Möbitz 2 second degree AV block, 3:2 conduction, with bigeminy Indeterminate axis â140o Right bundle branch block Anteroseptal infarction, probably old Comment: In all instances of t
Möbitz 2 Block
Report: Sinus rhythm Second degree AV block, Möbitz 2 Right bundle branch block Comment: The conducted P waves show no increment in their PR intervals prior to the blocked one - a clear-cut case of Möbitz 2 block. Typically, the QRS itself is prolong
