Pacemaker Blues
Report: [Code Blue] Pacemaker rhythm 72/min 1 QRS 0.36” 2 Pacemaker rhythm 72/min 1 QRS 0.20” 2 AV dissociation 2 Accelerated idioventricular rhythm 78-84/min 2 Comment: The QRS complex width - in paced beats, bundle branch blocks, or VEBs - gener
Hyperacute Anterior Infarction
Report:Sinus rhythm 66/min Acute anterior infarction Comment:The term hyperacute refers to increase in T wave height at a very early stage of myocardial infarction. The waves need not be large. As Goldberger put it6, âthe amplitude of hyperacute T wav
AIVR in Anterior Infarction
Report:Accelerated idioventricular rhythm 72/min Supraventricular capture beats Ventricular fusion beats (middle of the trace) Acute extensive anterior infarction Comment:AIVR is commoner in inferior than anterior infarcts, but reperfusion tends to ev
Inferior Infarction and AIVR
Report:Sinus rhythm & arrhythmia 80/min Accelerated idioventricular rhythm 80/min Retrograde conduction Fusion beat (third last complex) Acute inferior infarction Comment:The sinus cycle lengthens over the first three beats, allowing the AIVR to take
Acute Inferior Infarction: AIVR
Report:Sinus rhythm Accelerated idioventricular rhythm 88/min Acute inferior infarction Comment:There are only three sinus captures present, just enough to make the diagnosis. The computer diagnosed LBBB with âmarked ST elevation â possibly due to
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 & Paper-End Mark
Report:Junctional or accelerated idioventricular rhythm (AIVR) 52/min. 1:1 retrograde conduction. Comment:The sinus rhythm is completely regular in brain death and usually faster than while vagal tone was still extant, except in profound hypothermia. Th
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
AIVR & Quadrigeminal VEBs
Report: Accelerated idioventricular rhythm 90/min (AIVR) Retrograde VA conduction Wenckebach phenomenon VEBs in quadrigeminy Fully compensatory pauses (in the AIVR) testing Comment: The first impression is that of dissociated sinus rhythm due to vari
AIVR & Retrograde Conduction
Report: Sinus arrhythmia VEB (second complex in the top strip) Atrial (?junctional) escape complex (9th in the top strip) Accelerated idioventricular rhythm 86-89/min Retrograde conduction Fusion beats Comment: Typically, the retrograde 1:1 conducti
