Atrial Fibrillation with Complete AV Block
Report:Atrial fibrillation Third degree AV block VEB Junctional escape rhythm 42/min Possible old inferior MI Diffuse ST/T changes Comment:The ventricular rate is completely regular and slow, disturbed only by a single VEB. The VEB looks like LBBB,
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
Congenital Heart Block with Long QT Interval
Report: Sinus rhythm 100 - 110/min Third degree AV block Junctional escape rhythm 48/min VEB SVEB Prolonged QT interval 0.60â QTc 0.53â Comment: This case has been reported73. While it is not possible to exclude post-syncopal QT prolongation i
Over the Top
Report: Sinus rhythm First degree AV block (shortest PR 0.48â)[!xe "AV block:first degree:skipped P waves" \b!] Second degree AV block, Möbitz 1 (Wenckebach) Skipped P waves (over the top conduction)[!xe "P wave:skipped" \b!] Comment: This is quite
Sinus Bradycardia
Report:Sinus bradycardia 32/min Short QT interval QTc 0.31â Comment:Marked sinus bradycardia almost always signifies some form of sinoatrial block, often in the setting of sick sinus syndrome. The short QT interval is more interesting. The most like
Disappearing P Waves
Report: Sinus rhythm Second degree AV block, Möbitz 1 Comment:The P waves come to be superimposed on T waves as the PR intervals lengthen. Strange to say, this merger of superimposed waves has come to be called fusion by some cardiologists34. The less
Alternating Retrograde Conduction in Accelerated Junctional Rhythm
Report:Accelerated junctional rhythm 92/min 2:1 retrograde block Right axis deviation Lateral infarction, acute or recent Borderline small voltage in frontal leads Electrical alternans V1 Comment:One would be tempted to say that this trace is an exa
Sinus Bigeminy
Report: Sinus rhythm 98/min (top) Sino-atrial 3:2 Möbitz 1 exit block?[!xe "Sino-atrial exit block:bigeminy" \b!] Bigeminy[!xe "Bigeminy:sinus" \b!] Comment: The differential diagnosis includes SVEBs in bigeminy (where Pâ waves look different to sin
Single Beat ECG
Report:Atrial flutter 180/min Third degree AV block Ventricular escape beat Comment:This looks like an agonal ECG, taken by inertia of the admission âworkupâ when the patient was already as good as dead. Not so: he was transferred to CCU, where he
Atrial Flutter with High-Grade AV Block
Report:Atrial flutter 260/min Advanced (high-grade) AV block Possible junctional escape beats Nonspecific ST/T changes Comment:Complete block is excluded by the irregularity of the admittedly slow ventricular rate. Furthermore, one looks for the short
