It's the ECG's that george rejects that makes George's ECG's the best.
Over the Top
Report: Sinus rhythm First degree AV block (shortest PR 0.48”)[!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 a
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 “workup” when the patient was already as good as dead. Not so: he was transferred to CCU, where he also
Sinus Bradycardia
Report:Sinus bradycardia 32/min Short QT interval QTc 0.31” 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 likely
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 s
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 P’ waves look different to sinus
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
Sleeper With No Apnœa
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
Sustained Concealed Conduction on Holter Monitor
Report:Sinus rhythm 60 – 70/min Borderline first degree AV block Second degree AV block, Wenckebach (Möbitz 1) type VEB, interpolated Concealed retrograde conduction in three subsequent cycles Comment:Sustained PR interval prolongation after an inter
Congenital Complete Heart Block
Report:Sinus rhythm 100 – 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 the
