Bigeminy and Trigeminy: Atrial Flutter
Report:Atrial flutter 250/min Alternating 4:1 & 2:1 (2:1 + 3:2) conduction, with bigeminy (top) 2:1 + 4:3 conduction, with trigeminy (bottom) Comment:Typical flutter has a basic 2:1 block and a more distal, Wenckebach block; this combination accounts f
Wrong Footprints
Report:Sinus rhythm Non-conducted SVEBs Trigeminy Left bundle branch block Comment:Surprising number of staff reported these strips as Wenckebach (Möbitz 1) second degree AV block. The reason may be the memory of Marriott's injunction to "recognise
Escape-Capture Bigeminy
Report: Sinus rhythm 92/min Second degree AV block, probably 2:1[!xe "AV block:second degree:2-1" \b!] Junctional escape beats[!xe "Junctional escape beats:second degree AV block" \b!] Escape-capture bigeminy Non-phasic aberration[!xe "Aberrant conduc
Unfinished Wenckebach
Report:Sinus rhythm 76/min Wenckebach phenomenon Atrial trigeminy, possible reentry beats of sinus origin, blocked Frequent VEBs, uniform Positive concordant precordial pattern Left atrial abnormality (LAA) Left anterior hemiblock (frontal axis â6
Interpolation in Alternate Cycles
Report:Sinus rhythm 51/min VEBs, interpolated in alternate cycles Trigeminy Non-specific ST/T changes Comment:The VEBs are typical, with nonsense axis and qR morphology in V1; their concealed retrograde conduction114, prolonging the PR intervals of th
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
Fusion VEBs in Trigeminy
Report:Sinus tachycardia VEBs in trigeminy Fusion beats Comment:The degree of fusion varies with the P-VEB interval. With only a minor degree of ventricular contribution to fusion, the late-diastolic VEBs may pass unnoticed or be mistaken for effects o
Complex Trigeminy: Quadrigeminy in Disguise
Report: Sinus rhythm 73/min VEB couplets in trigeminy Ventricular fusion beats (second in each couplet) Concealed retrograde conduction Comment: The first VEB is interpolated between the preceding sinus beat and a fusion beat; hence the fusion beats h
Bizarre Trigeminy
Report:Atrial fibrillation Advanced or complete AV block Ventricular (first triplet) and junctional escape beats VEBs in couplets Trigeminy Small voltage, frontal leads Vertical heart position Possible old anteroseptal infarction Comment:There is
VEBs: Retrograde Conduction
Report: Sinus rhythm VEBs, trigeminal, uniform Retrograde VA conduction Left atrial abnormality (LAA) Borderline right atrial abnormality (RAA) Probable old posterior infarction Nonspecific ST/T changes Comment: The compensatory pauses are longer t
