1o AV Block Expressing BBBB
Report: Sinus rhythm 77 â 82/min Left atrial abnormality (LAA) First degree AV block PR 0.22â Intermittent right bundle branch block + left anterior hemiblock PR 0.16â Nonspecific T wave changes Comment: At first, one would postulate a disso
Wenckebach AV Block in Marked Sinus Tachycardia
Report: Sinus tachycardia 138/min Second degree AV block, Möbitz 1 Probable acute inferior infarction Comment: It is unwise, generally, to diagnose infarction from rhythm strips, but this one has all three indicative changes of acute infarction: Q wav
Respiratory & Ventriculophasic Sinus Arrhythmia
Report: Sinus rhythm Respiratory sinus arrhythmia Ventriculophasic sinus arrhythmia Second degree AV block, Möbitz 1 Period of 2:1 conduction + one 5:4 cycle LVH with ST/T changes ± digoxin effect Comment: The ventriculophasic effect â P-P inter
Wenckebach Conduction of Sinus Tachycardia
Report: Sinus tachycardia 116/min SVEB Second degree AV block, Möbitz 1 Comment: Some of the blocked P waves look different in shape from others, due to their position on the preceding T wave. Their timing easily distinguishes them from blocked SVEBs.
Junctional Escapes in Wenckebach Pauses
Report:Sinus rhythm Second degree AV block, Möbitz 1 Junctional escape beats Non-phasic aberrant conduction Comment:The ectopic complexes can be either premature or late (escape) beats. Here the Wenckebach pauses are interrupted by junctional escapes
Ventriculophasic Sinus Arrhythmia
Report:Sinus rhythm. Second degree AV block, Möbitz 1 Ventriculophasic sinus arrhythmia. Phasic aberrant conduction Comment:The âshortâ complexes are aberrantly conducted sinus beats. The promotion from 2:1 to 3:2 block has produced a long-short
Unusual Wenckebach Sequences
Report:Sinus arrhythmia Second degree AV block, Möbitz 1 Bradycardia-dependent LBBB (4th beat in the top strip) ? Respiratory artefact ? Bradycardia-dependent incomplete LBBB ? Junctional escape beats with non-phasic aberrant conduction Comment:T
Verapamil Wenckebach
Report: Sinus rhythm Möbitz 1 (Wenckebach) second degree AV block Comment: This is a very low-grade block and the patient is monitored anyway. Nothing needs be done immediately. In the long term, an antihypertensive without AV blocking properties shoul
Three Causes of Pauses & Many Diagnoses
Report:Sinus rhythm 88 - 92/min Left atrial abnormality (LAA) P wave 0.12â SVEB, non-conducted VEBs, late-diastolic Ventricular fusion beat (third last complex in the bottom strip) Junctional escape (top strip) and premature beat (bottom strip), R
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
