Rate-Dependent LBBB
Report: Sinus rhythm 90/min SVEBs, blocked, in bigeminy Left bundle branch block, rate-dependent Comment: The blocked atrial extrasystoles are discretely etched on the onset of the T wave. A sustained run could be mistaken for sinus bradycardia 50/min.
Transient LBBB with RAD & Prolonged Interpolation Effect
Report:Sinus rhythm and arrhythmia VEBs, interpolated Sustained PR interval prolongation Left bundle branch block Transient right axis deviation post-VEBs Possible old anterolateral infarction Comment:Two things are of interest here: diminuendo PR i
Alternating Left Anterior Hemiblock
Report:Sinus tachycardia 102/min Alternating LAD, probably LAHB Acute or recent anterior infarction Comment:The presenting symptoms of both angina and infarction are often atypical in women5. This patient had post-infarction angina at the time of this
2:1 AV Block in Bad Company
Report:Sinus rhythm 74/min 2:1 second degree AV block Right axis deviation (RAD) +120o Left posterior hemiblock Right bundle branch block Ventriculophasic sinus arrhythmia Comment:The patient had no history of heart disease and had been on cimetidin
Phasic and Non-Phasic Aberrant Conduction
Report:Sinus bradycardia, probably 46 â 50/min SVEBs, LBBB & incomplete RBBB phasic aberrant conduction Junctional escape beats, non-phasic aberrant conduction Left axis deviation, possible LAHB Comment:The allorhythmia consists of repetitive triple
Retrograde First Degree Ventriculoatrial Block
Report:Junctional rhythm 37/min Retrograde 1o ventriculoatrial (VA) block VA interval 0.28â Right bundle branch block QRS 0.14â Probable old inferoposterolateral infarction Nonspecific ST/T changes Comment:There is a 1:1 retrograde conduction;
Pacemaker & Native Escape-Capture Bigeminy
Report:Sinus bradycardia 37/min Junctional & pacemaker escape beats Escape-capture bigeminy Pseudofusion beats Fusion beat Ventricular conduction defect, unspecified Comment:The escape-capture phenomenon depends in this case on sinus bradycardia. T
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
Dual Conduction and SVT
Report: Sinus rhythm Dual PR interval: 0.14â and 0.30â Comment: The two PR intervals alternated over periods of minutes, finally attracting the attention of the ICU night staff. Unfortunately, no spontaneous change was recorded. In the morning, I g
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
