RBBB as Monophasic R wave in V1
Report:Sinus rhythm 94/min Left anterior hemiblock QRS axis â40o Right bundle branch block Comment:RBBB can be manifest as pure R wave in V1, especially in the presence of a hemiblock. One could not, without a baseline trace in sinus rhythm, diagnos
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
1o AV Block Expressing BBBB
Report: Sinus rhythm 77 â 82/min Left atrial abnormality (LAA) First degree AV block PR 0.22â Intermittent right bundle branch block + left anterior hemiblock PR 0.16â Nonspecific T wave changes Comment: At first, one would postulate a disso
Left Axis Deviation: LAHB
Report:Atrial & sinus rhythm 76/min Left atrial abnormality (LAA) Left anterior hemiblock Axis â40o Early transition Left ventricular hypertrophy with ST/T changes Comment:There is a typical qR and rS pattern in leads 1 and 3, respectively. Also t
Invisible LAHB Causing 2:1 AV Block
Report:Sinus tachycardia 120/min 2:1 AV block Right axis deviation +140o Right bundle branch block Possible old anterolateral infarction Comment:The cause of the RAD may be RVH or old anterolateral MI but the former was certainly not present clinical
Alternating (2:1) Right Bundle Branch Block
Report: Sinus tachycardia 126/min Left anterior hemiblock Frontal plane axis â60o Alternating right bundle branch block Poor R wave progression Nonspecific ST/T changes Comment: The diagnosis depends, critically, on identical PR interval in all th
Escape-Capture Bigeminy in AF
Report: Atrial fibrillation High-grade or complete AV block Junctional rhythm 39/min Pacemaker (escape) rhythm Escape-capture bigeminy Left anterior hemiblock (LAHB) Right bundle branch block Anteroseptal infarction, age uncertain ST/T changes con
2:1 & Advanced 2o AV Block
Report: Sinus tachycardia 125/min Left atrial abnormality (LAA) Second degree AV block, 2:1 & advanced First degree AV block (PR 0.28â) in conducted beats VEB (ventricular escape beat) Left anterior hemiblock Right bundle branch block, atypical L
Long Latency
Report: Sinus rhythm Latent (first degree) AV block PR 0.90â Left anterior hemiblock Right bundle branch block Old anterior infarction Comment: This is the longest sustained first degree AV block I have seen. It is possible that the rhythm is othe
