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
Complete Heart Block
Report:Sinus rhythm 72/min Third degree AV block Junctional escape rhythm 31/min Left atrial abnormality (LAA) Rightward axis, unusual for age Right bundle branch block Prolonged QT interval (0.70â) QTc 0.50â Comment:This is a typical complete
Empty Wenckebach Pauses
Report: Sinus rhythm SVEB (second QRS, bottom strip) Second degree AV block, Möbitz 1 Junctional beats, non-conducted ?Reentry beats of sinus origin Atrial fusion beats, non-conducted Comment: In the upper strips, the Wenckebach sequences are termi
AV Dissociation With Interference
Report: Sinus tachycardia 115/min Second degree AV block, probably Möbitz 1 (Wenckebach) type Wenckebach pauses with two blocked P waves? Junctional escape beats and rhythm? Comment: This is a surprisingly difficult strip to interpret completely. Whi
Möbitz 2 Block
Report: Sinus rhythm First degree AV block PR 0.22â Second degree AV block, Möbitz 2 Left posterior hemiblock Right bundle branch block Comment: The fixity of the PR interval rules out Möbitz 1 (Wenckebach) mechanism for the AV block. Almost inv
Digoxin-Induced Wenckebach
Report: Sinus arrhythmia Second degree AV block, Möbitz 1 Comment:The respiratory effect on the QRS size is seen throughout. It may be tempting to assume the first and largest QRS in each sequence is a junctional escape beat, with non-phasic aberranc
The Bix Rule
Report: Sinus tachycardia 104/min Second degree 2:1 AV block Comment: The rule states that if a P wave (or a Pâ wave) is half-way between the QRS complexes, it probably has a companion P wave hidden within the QRS complex47. This is demonstrated below
Vagotonia: Advanced Second Degree AV Block
Report: Sinus rhythm Advanced second degree AV block[!xe "Second degree AV block" \t "See AV block, second degree"!] Period of asystole Ventriculophasic sinus arrhythmia Comment: Vagally-mediated bradyarrhythmias may, at times, be fatal. Vast majori
Echo (Reentry) Beats of Junctional Origin
Report: Top strip: Sinus bradycardia, progressive First degree AV block PR 0.24â Junctional escape beats Retrograde first degree AV block (RP 0.28â) Reentry (echo) beats of junctional origin Antegrade PR interval now 0.20â Incomplete RBBB B
Skipped P Waves in Wenckebach Conduction
Report: Sinus tachycardia 120-128/min First degree AV block Second degree AV block, Möbitz 1 Periods of 3:2 conduction, with bigeminy Right bundle branch block Pacemaker rhythm 72/min Fusion and pseudofusion beats Comment: The key to correct inter
