Sinus Bradycardia & AIVR
Report: Sinus bradycardia 37 - 44/min Second degree AV block(unspecified) First degree AV block Accelerated idioventricular rhythm (AIVR) 57/min AV dissociation with interference ST segment elevation consistent with ischæmia/infarction Comment: Thi
Rule of Bigeminy: VEBs & SVEBs
Report: Sinus rhythm First degree AV block (PR 0.26â) Right bundle branch block (QRS 0.14â) VEBs SVEBs, junctional Comment: All four SVEBs follow, after one cycle, the VEBs and the last VEB in the bottom strip follows a SVEB, perhaps reflecting t
AIVR: AV Dissociation
Report: Sinus tachycardia 100 - 110/min Accelerated idioventricular rhythm (AIVR) 98/min AV dissociation Fusion beats Comment: Like digoxin, hypokalæmia enhances subsidiary pacemaker automaticity. Even if the AIVR persisted after correction of hypoka
AV Dissociation in VT
Report: Sinus tachycardia 127/min Left atrial abnormality (LAA) First degree AV block (PR 0.22â) Axis -100o (Northwest, no-manâs land, ânonsenseâ axis) Probable left anterior hemiblock Right bundle branch block VEB, probably fusion beat (5th
Ventricular Fusion Rhythm
Report: Sinus rhythm Accelerated idioventricular rhythm (AIVR) AV dissociation Ventricular fusion beats Comment: The periods of AIVR in the upper strips are introduced or terminated by fusion complexes; the 8-beat run in the bottom strip consists enti
Runs of Ventricular Tachycardia
Report:Sinus rhythm 85/min VEBs, couplets Runs of ventricular tachycardia 164/min Left atrial abnormality (LAA) Left bundle branch block V2-V3 lead reversal Comment:The patient had many brief runs of VT, always introduced by the qR VEB couplets. The
Ventricular Tachycardia: Electrical Alternans
Report:Ventricular tachycardia 153/min Sinus rhythm 86/min Complete A-V dissociation Comment:This is a fairly typical VT, LBBB-like, with slurred V1 downstroke. The diagnosis is strengthened by the obvious A-V dissociation. In lead 2 and V2-3, there i
Slow Bidirectional Tachycardia
Report: Bidirectional tachycardia 104/min Retrograde VA conduction Junctional escape beats AV dissociation Sinus rhythm 95 â 98/min Overdrive (post-ectopic) SA suppression Comment: The rhythm is obviously bigeminal, with narrow rSRâ complexes
Alternate Cycle Antecedent P Waves
Report:Ventricular tachycardia 125/min Probable 2:1 retrograde conduction Comment:The diagnosis of VT is supported by the QRS duration of 0.18â, the indeterminate abnormal axis and the left rabbit ear in V1 being taller than the right. The relativel
Fast Ventricular Tachycardia with Visible AV Dissociation
Report: Ventricular tachycardia 214/min AV dissociation Comment: The morphology is somewhat equivocal, V1 showing RRâ complexes with right rabbit ear taller than the left; nevertheless, they are essentially monophasic and over 0.14â, favouring ectop
