Bigeminal AIVR: Inferoposterolateral MI
Report:Sinus bradycardia (rate uncertain) Accelerated idioventricular rhythm 77/min Bigeminy ? exit block Nonspecific ST/T changes Comment:The infarction cannot of course be diagnosed in the original tracing and what was left of its evidence after ang
Agonal Rhythm
Report: Atrial standstill VEBs (ventricular escape beats) Ventricular tachycardia 110/min Comment: Despite its irregular rate, the broad complex tachycardia is unlikely to represent ventricular response to atrial fibrillation. The agonal rhythm is usua
Chronotropic Incompetence
Report:Atrial fibrillation with âcontrolledâ response Accelerated idioventricular rhythm (AIVR) VEBs Comment:Although the ventricular rate appears favourable, it is in fact inappropriately slow in the setting of shock, pulmonary hypertension (see t
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
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
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
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
Sudden Ventricular Standstill
Report: Sinus tachycardia 100/min Borderline first degree AV block Left bundle branch block Third degree AV block Ventricular escape beats (bottom) Comment: This is a typical example of AV block in acute anterior infarction: RBBB or LBBB (as here) fo
Complete Heart Block: Anterior MI
Report: Sinus tachycardia Third degree AV block Ventricular escape beats and rhythm Comment: The slowing of the sinus rate in the forth and fifth strips was ominous, reflecting sinus node hypoxia or ischæmia. The ventricular escapes were slow and unr
Junctional Escapes in Wenckebach Pauses
Report:Sinus rhythm Second degree AV block, Möbitz 1 Junctional escape beats Non-phasic aberrant conduction Comment:The ectopic complexes can be either premature or late (escape) beats. Here the Wenckebach pauses are interrupted by junctional escapes
