It's the ECG's that george rejects that makes George's ECG's the best.
AIVR & Quadrigeminal VEBs
Report: Accelerated idioventricular rhythm 90/min (AIVR) Retrograde VA conduction Wenckebach phenomenon VEBs in quadrigeminy Fully compensatory pauses (in the AIVR) Comment: The first impression is that of dissociated sinus rhythm due to variable P
Alternate-Beat Wenckebach Caused by VEBs
Report:Sinus rhythm 92/min VEBs, couplets and triplets R-on-T phenomenon Wenckebach second degree AV block for alternate P waves Acute or recent inferior infarction Comment:The first two consecutively conducted P waves show slight but definite PR i
Three Causes of Pauses & Many Diagnoses
Report:Sinus rhythm 88 - 92/min Left atrial abnormality (LAA) P wave 0.12” 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), RBB
VEB: the Compensatory Pause
Report:Sinus rhythm 62/min First degree AV block (PR 0.22”) VEB Left bundle branch block Comment:The P waves are sharply etched in V1 and the one blocked by the VEB is seen quite clearly. There is no need to measure the compensatory pause containing i
Right Ventricular Outflow Tract Tachycardia
Report:Ventricular tachycardia 155/min Possible A-V dissociation Comment:The tachycardia complexes are just under 0.12” in duration and have, in a way, left bundle branch block morphology with marked (+100o) right axis deviation. There appear to be diss
VEBs: Trigeminy & Trigeminy
Report:Sinus arrhythmia Left atrial abnormality (LAA) First degree AV block Atrial ectopic beat (second P wave in the bottom strip) VEBs in trigeminy Concealed retrograde conduction Comment:In the top strip, every third P wave is blocked by a VEB. I
Interpolated VEBs & Couplets
Report:Sinus rhythm VEBs, some interpolated, some (bottom strip) in couplets (pairs) Comment:In the top strip, the first VEB blocks the ensuing sinus P wave, creating a fully compensatory pause. The other two penetrate the AV junction retrogradely (conc
Another RVOT VT: Retrograde 1:1 Conduction
Report:Ventricular tachycardia 168/min Comment:This is a good example where conduction sequences and QRS morphology do not help in making the diagnosis. Each QRS is followed after 0.18” by a sharp upright P wave in V1 consistent with a retrograde P wave;
Junctional Rhythm: Fusion Trigeminy
Report: Junctional rhythm 65/min Left bundle branch block VEBs in trigeminy, late-diastolic Ventricular fusion beats Comment: The junctional focus appears protected from the VEBs; the pauses are fully compensatory. The morphology of the junctional bea
Two for the Price of One
Report: Sinus rhythm 80/min (top) & 91/min (bottom) VEBs, two couplets Fully compensatory pauses (top) Comment: Depending on the sinus rate and the timing of the VEBs, a couplet may replace one or two sinus beats; usually it replaces two, as in the bot
