AIVR
Report:Accelerated idioventricular rhythm 84/min Marked respiratory swing Comment:The 0.16â qRRâ complexes in V1 are the best evidence for the ventricular ectopic origin of the rhythm; lack of septal q in lead 1 and rS in V6 also lend some support.
VEBs in Quadrigeminy
Report:Sinus rhythm 98/min VEBs, one couplet and three triplets (runs of VT) Left atrial abnormality (LAA) Possible old inferior infarction Comment:The VEBs are undoubtedly what they look like, with taller left rabbit ear in an R wave in V1. They grea
More VEBs in Quadrigeminy
Report:Sinus rhythm VEBs in couplets, quadrigeminy Left atrial abnormality (LAA) Probable LVH with STT changes Lead V3 missing Comment:Each quadrigeminal grouping consists of two (Rosenbaum) VEBs and two sinus beats. The second VEB in each couplet ap
VEBs After SVEBs
Report:Sinus tachycardia 112/min SVEBs VEBs Early transition Nonspecific ST/T changes Comment:The second and third VEB follow obvious SVEBs; the predecessor of the first one remains unseen. However, in this patient, all the VEBs seen in several ECGs
Retrograde Conduction of AIVR: From the Second Beat Onward
Report: Sinus rhythm 75/min PR interval 0.20â Intraventricular conduction delay, probably LBBB QRS 0.12â Accelerated idioventricular rhythm (AIVR) 96/min Retrograde VA conduction RP interval 0.20â Comment: The retrograde and antegrade conduct
Rabbit Ears For and Against
Report:Upper strip: Sinus tachycardia 104/min VEBs, late-diastolic (R-on-P âphenomenonâ) Lower strip: Sinus rhythm SVEBs, probably of atrial origin RBBB aberrancy Couplet, second SVEB non-conducted Comment:Looking at the rabbit from behind, if
Right Ventricular Outflow Tract Tachycardia
Report:Ventricular tachycardia 155/min Possible A-V dissociation Comment:The tachycardia complexes are just under 0.12â in duration and have, in a way, left bundle branch block morphology with marked (+100o) right axis deviation. There appear to be di
VEBs: Trigeminy & Trigeminy
Report:Sinus arrhythmia Left atrial abnormality (LAA) First degree AV block Atrial ectopic beat (second P wave in the bottom strip) VEBs in trigeminy Concealed retrograde conduction Comment:In the top strip, every third P wave is blocked by a VEB. I
Minuscule VEBs
Report: Sinus rhythm 90/min VEBs, bigeminal and trigeminal Comment: The minuscule VEBs simulate blocked Pâ waves except that (i) they either march through sinus P waves (upper strip) or, at times, (ii) create retrograde P waves of their own (lower str
Iatrogenous Pheochromocytoma
Report:Sinus tachycardia 148 -160/min VEBs Frequent Multiform Bigeminal Couplets Run of 4 (VT) Comment:The almost six fold rise in the systolic BP was a surprise. Once the patient survived the effects of the generous dose of adrenaline (a dose norm
