Wenckebach AV Block in Acute Inferior Infarction
Report:Sinus rhythm 90/min Möbitz 1 (Wenckebach) second degree AV block Intraventricular conduction defect (IVCD) QRS 0.12â Acute inferior infarction Comment:The most striking feature are the marked precordial reciprocal changes, indicating extens
Inferoposterior Infarction
Report:Sinus tachycardia 108/min Accelerated junctional rhythm 98/min SVEB (6th complex, a pseudofusion beat) Movement artefact Pacemaker, electronic, 70/min Failure to sense Acute infero(postero)lateral infarction Low voltage in frontal leads Com
Old and New Inferior Infarction
Report:Sinus bradycardia 44/min First degree AV block Right bundle branch block Acute inferior infarction Comment:The splayed, low-amplitude P waves are difficult to time with respect to possible 2:1 block at 88/min. Even isorhythmic AV dissociation c
Paced Tricuspid Atresia
Report:Atrial pacemaker rhythm 111/min Left axis deviation â60o Left ventricular hypertrophy with ST/T changes Comment:The child had Fontan repair119 (atriopulmonary connection) in infancy. His combination of LVH and LAD is characteristic of tricus
Isoelectric Lead 1
Report: Sinus rhythm Third degree AV block Pacemaker rhythm Reversed arms/legs leads! Comment: Flat Lead 1 is virtually pathognomonic of legs/arms reversal. The P waves also assume retrograde polarity (one is seen in the last cycle in leads 1, 2, 3).
Sluggish Performance of Fat Complexes
Report: Atrial fibrillation with controlled response (top & bottom) Mean BP 85 & 83 mmHg Pacemaker rhythm (middle) Mean BP 68 mmHg Comment: The slight asynchrony in contraction secondary to LBBB-type conduction becomes significant in a critically imp
Complete Chest Lead Reversal
Report:Atrial pacemaker rhythm 78/min Complete chest lead reversal Possible left ventricular hypertrophy Comment:This is a rare variant of lead reversal. It happens when the entire block of V-lead terminals is rotated 180o and inserted into the machine
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
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
Pacemaker: Escape-Capture Bigeminy
Report:Sinus tachycardia 100/min First degree AV block (PR 0.28") Second degree AV block. Right bundle branch block Pacemaker (escape) beats Escape-capture bigeminy Comment:Before Bradley and Marriott's classical description6, this rhythm was called
