It's the ECG's that george rejects that makes George's ECG's the best.
Neostigmine Toxicity
Report:Sinus rhythm 3:2 sino-atrial exit block Nonspecific T wave changes Comment:The patient was paralysed by vecuronium for a CAT scan after a traffic accident; she was brought back to Casualty and the relaxant was reversed with 5 mg neostigmine
Bigeminy in Sino-Atrial Exit Block
Report: Sinus rhythm approximately 90/min Left atrial abnormality (LAA) 3:2 Sino-atrial exit block, Möbitz 1 (Wenckebach) Bigeminy Left axis deviation –35o Comment: Bigeminy like this one has to be differentiated from atrial ectopic bigeminy: half
Notched P Wave
Report: Sinus rhythm Left atrial abnormality (LAA) Widely notched P wave Sino-atrial exit block Probable atrial infarction Comment: The wide P wave (0.18”) is produced by an atrial conduction defect, usually involving the interatrial tract (Bachm
Post-Ectopic Sino-Atrial Depression
Report:Sinus rhythm 74/min SVEBs, one RBBB-aberrant Marked post-ectopic SA depression (overdrive suppression) Left bundle branch block Comment:The 7th beat’s P’ distorts the T wave of the preceding sinus beat. The pause containing the SVEB is more t
Sino-Atrial Wenckebach
Report: Sinus rhythm Left atrial abnormality (LAA) 5:4 and 4:3 sino-atrial exit block, Möbitz 1 Normal QRS/T Comment: In each pause, an entire P-QRS-T sequence is missing; the pause itself is less long than two sinus cycles. There is slight accelera
Sino-Atrial Wenckebach
Report:Sinus rhythm Sino-atrial exit block, Möbitz 1 Left atrial abnormality (LAA) AV block, Möbitz 1, incomplete sequences Prolonged QT interval Comment:This is an example of one form of block preventing the full expression of another: the AV nod
Sinoatrial Block: CVA
Report:Sinus rhythm Sinus pauses - probable Wenckebach exit block Junctional escape beats and rhythm Atrial fusion beats SVEB. Comment:The sinus cycles tend to shorten before the pause, a characteristic of Möbitz 1 (Wenckebach) exit block. There is
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 Arrhythmia or SA Exit Block?
Report: Sinus rhythm Sino-atrial exit block Comment: All the groups display the characteristic acceleration before the pause. This is the hallmark of Wenckebach (Möbitz 1) sino-atrial exit block, only slightly modified by true (respiratory) sinus ar
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
