RBBB & Contralateral Escape Beats
Report: Atrial fibrillation with slow response Right bundle branch block Borderline left axis deviation â30o Ventricular escape beats with left bundle branch block morphology Nonspecific ST/T changes Comment: One instinctively looks (or should look
Supernormal Conduction in RBBB
Report:Sinus rhythm 72/min SVEBs, one couplet Right bundle branch block Supernormal conduction Comment:The SVEBs are all preceded by Pâ, resetting the sinus pacemaker. What is unusual and unexpected is their normal intraventricular conduction despit
AV Block: Nodal or Ventricular?
Report:Sinus rhythm Second degree AV block Intermittent right bundle branch block & left posterior hemiblock Prolonged QT interval Comment:The PR interval lengthens between the first and the second beat, but fails to grow observably longer between the
Right Axis Deviation: RVH
Report:Sinus rhythm 92/min Biatrial abnormality (LAA + RAA) Right axis deviation +115o Right bundle branch block Inferior and anterior Q waves ? cause Probable right ventricular hypertrophy Comment:The patient had very large dilated and hypertrophie
Bradycardia-Dependent RBBB
Report: Sinus/atrial rhythm Shifting pacemaker First degree AV block Second degree AV block, Möbitz I Blocked SVEBs, ?reentry of atrial origin Bradycardia-dependent right bundle branch block Comment: This is the same patient as in Case 1. All the
Conducted LPHB and Escaping LAHB
Report:Sinus rhythm 82/min Left atrial abnormality (LAA) 2:1 AV block Right bundle branch block Left posterior hemiblock Junctional escape (first two) beats RBBB + LAHB morphology Nonspecific ST/T changes Comment:Most commonly, the escape rhythm h
The LEOPARD Syndrome
Report:Sinus tachycardia 122/min Right axis deviation +150o Right bundle branch block Nonspecific ST/T changes Lead V1 â V3 reversal Comment:There are multiple eponyms for this rare autosomal dominant syndrome but the acronym LEOPARD is the most co
RBBB with Right and Left Axis
Report:Sinus rhythm SVEBs, bigeminal Left axis deviation in sinus beats, probably LAHB Right axis deviation in SVEBs due to LPHB Right bundle branch block throughout Borderline T wave changes Comment:With RBBB the frontal axis is determined by the i
RBBB with Amputated Primary R Wave
Report:Sinus rhythm 95/min Right axis deviation Right bundle branch block Recent anterior infarct Comment:The QR complex in V1 is still RBBB since the delay is all in the RV territory. Before the infarction it was an rSrâ of normal duration (not sho
Rate-Dependent RBBB
Report:Sinus rhythm 75/min First degree AV block PR 0.22â VEBs, uniform Rate-dependent right bundle branch block Borderline ST segment depression in 2, aVF Comment:Without a hemiblock, RBBB has a qRS pattern in V6. This is a normal, âseptalâ q
