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
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
LBBB and Cardiac Memory
Report:Sinus rhythm 77/min SVEBs First degree AV block PR interval 0.26â Aberrant conduction, LBBB type Anteroseptal T wave inversion V1-V3 Prolonged QTc 0.49â Comment:Sustained LBBB or RV electronic pacing may induce T wave inversion not unlik
Lean Children of Fat Parents
Report: Sinus arrhythmia ? Sino-atrial exit block, Möbitz I Right bundle branch block Pacemaker escape beats Ventricular fusion beats âNormalisationâ of QRS Comment: Both ânormalâ complexes (one in each strip) and the small RBBB complex (6
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
Ventricular Fusion Beats
Report: Sinus rhythm 78/min Third degree A V block ldioventricular (fascicular) escape rhythms 39 -48/min Right & left bundle branch block morphologies "normalised" ventricular fusion beats Comment: The two escape foci reside, presumably, in the two b
Atypical LBBB
Report:Sinus rhythm 70/min Borderline left atrial abnormality Left bundle branch block Comment:The S wave downstroke is slurred, while the upstroke is brisk, like in VEBs. This is unusual, most likely due to an old infarction. In every other respect, h
LAD: Inferior MI + LAHB
Report:Atrial tachycardia approx. 150/min with block (PAT with block) Right bundle branch block Left anterior hemiblock Old inferior infarction Small voltage Comment:Typically, V1 is the only lead with easily discerned atrial waves in PAT with block.
Alternating Complete & Incomplete LBBB
Report:Sinus rhythm 67/min Alternating complete & incomplete left bundle branch block Probable LVH Comment:The complete LBBB, if the patient lives long enough, will probably become permanent. At this stage it is still rate-dependent: slowing the sinus
WPW Conduction Masking Ischæmia
Report:Sinus rhythm 56/min Intermittent Wolff-Parkinson-White âBâ conduction Comment:The last three beats are conducted normally, in V1 rhythm strip and anterolateral leads V4-6. The ST segment is straight and horizontal in V6, but not enough to com
