It's the ECG's that george rejects that makes George's ECG's the best.
Heart Transplant: Atrial ‘Parasystole’
Report: Top strip: Sinus rhythm 86/min Short PR interval 0.10” Sinus rhythm (non-conducted) 76 - 78/min Atrial pseudofusion beat (middle of the strip) Bottom strip: Sinus rhythm 89/min Short PR interval 0.10” Sinus rhythm (non-conducted) 89/min C
AV Block in Inferior Infarction
Report: Top: Sinus rhythm VEB Third degree AV block Junctional escape rhythm 42/min Second strip: Sinus tachycardia 104/min Second degree AV block, 2:1 conduction First degree AV block in conducted beats (PR 0.44”) Third strip: Sinus tachycardi
AV Block with Low Output
Report: Sinus tachycardia Second degree AV block, Möbitz 1 (Wenckebach)[!xe "AV block:second degree:Möbitz 1" \b!] 2:1 & 3:2 conduction Comment: Low output a fortnight after the acute event is difficult problem. The best strategy is to try and ‘sti
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. Whil
R-on-P Bigeminal Tachycardia
Report: (Lead V1) Sinus tachycardia 108/min Incomplete right bundle branch block VEBs (late-diastolic, R-on-P) in bigeminy Comment: The broader complexes, terminating slightly shorter cycles, fall at the end of sinus P waves. A “tad of fusion” cannot
Möbitz 2 Block
Report: Sinus rhythm First degree AV block PR 0.22” 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 invar
Sino-Atrial Exit Block
Report:Sinus rhythm 52 – 54/min Sino-atrial exit block Bigeminy Nonspecific T wave changes Comment:There are two long cycles. One is slightly longer, the other slightly shorter than twice the preceding P-P cycle. Allowing for some sinus arrhythmia
Sinus Arrest: Asystole
Report: Sinus rhythm 60 – 70/min First degree AV block (PR 0.24”) Second degree AV block (unspecified - movement artefact over the last conducted P wave) Sinus arrest (middle) Sinus tachycardia 104/min (bottom) Third degree AV block Junctional esc
Isoprenaline Tachycardia
Report: Sinus tachycardia 108/min 2:1 AV block (top) Sinus tachycardia 150/min 2:1 & 3:2 Wenckebach AV block (middle) Sinus tachycardia 165/min (bottom) First degree AV block 1:1 conduction Comment: Isoprenaline helped the bradycardia, but at a pri
Sino-Atrial Exit Block
Report:Sinus rhythm 74/min 3:2 sino-atrial exit block Bigeminy Negative U waves in lead 1 Comment:The same comments can be made here as for the preceding Case 93. It, too, could have Möbitz 2 mechanism. Below (Fig 94a) is another trace, with long c
