Congenital Complete Heart Block
Report:Sinus rhythm 100 â 108/min Third degree AV block Junctional escape rhythm 54/min Nonspecific T wave changes Comment:The criteria for AV block as the cause of AV dissociation are fulfilled in that the atrial rate is almost twice faster than th
Sleeper With No ApnÅa
Report:Sinus arrhythmia Variable PR interval Second degree AV block, unspecified Single non-conducted P wave Comment:The block appears due to the respiratory variation of vagal tone and may have no more significance than a similar block induced in a h
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
