It's the ECG's that george rejects that makes George's ECG's the best.
Alternating Atrial Transport
Report: AV sequential pacemaker rhythm 78/min 4 Atrial capture in alternate cycles 3 Sinus ? atrial bigeminy in alternate cycles 3 Comment: Nobody would have looked hard at the atrial activity were the alternans not observed on the pressure display.
Establishing Pacemaker Dependence the Hard Way
Report: Sinus rhythm 1 Third degree AV block 3 Idioventricular rhythm 2 QT interval 0.86” 1 Sinus arrest 2 Pacemaker rhythm 1 Comment: The surgeon, who got rather flustered when told the heart had stopped, certainly established the diagnosis of thi
Double Interpolation
Report: Sinus rhythm 64/min 1 Pacemaker rhythm 62/min 1 Failure to sense (interpolated) 3 R-on-T pacing 2 Concealed retrograde conduction 3 Comment: The two rhythms, so to speak, pass through each other in a prolonged handover of the ventricles! Th
Reciprocal Rhythm
Report: Pacemaker rhythm 1 Variable rate 1 First degree AV (0.2 - 0.4”) and VA (0.47 - 0.51”) block 1 Bigeminy due to reentry (echo) beats of pacemaker origin 6 Ventricular conduction delay (unspecified) 1 Comment: All the complexes shown - atrial
Pseudo-Wenckebach in Pacemaker Rhythm
Report:Sinus tachycardia 100/min 1 Atrial-sensing ventricular pacemaker 2 Pseudo-Wenckebach periods 7 Comment:There is no acceleration of the distal chamber because the increases in AV interval are not decremental as in the “natural” Wenckebach; otherw
Paced Rhythm: Primary T Wave Changes
Report:Sequential pacemaker rhythm 1 SVEBs, with atrial-sensed pacing 2 Ventricular fusion 3 Primary T wave inversion in multiple leads 4 Comment:The pattern is that of global T wave inversion, usually not an ischæmic event. The T wave changes in this
Negative Concordant Precordial Pattern
Report: Sinus rhythm 1 Supraventricular ectopic beat 1 AV dissociation 5 Ventricular pacemaker rhythm 75/min with 100% capture 3 Comment: At first it appears that the large (therefore unipolar) pacemaker spikes track the P waves, but the latter gradu
Junctional Extrasystoles with RBBB Conduction
Report:Sinus rhythm 81/min 1 Atrial-sensing ventricular pacemaker 3 AV interval 0.10 sec 1 Junctional premature beats with RBBB conduction 4 ST/T changes consistent with ischæmia 1 Comment:Like in the previous case, there are large ventricle-pacing s
Failing Pacemaker
Report: Sinus rhythm 1 Probable third degree AV block 1 AV dissociation 1 Ventricular escape beats 1 Primary T wave changes 1 Probable old anterior infarction 1 Pacemaker rhythm 72/min 1 Intermittent failure to pace 1 Probable lead displacement 2
Isorhythmic Dissociation of a VVI Pacemaker
Report:Sinus rhythm 70/min 1 Ventricular pacemaker rhythm 70/min 4 AV interval 0.36 sec 5 Comment:The sinus P waves are not very well shown in the frontal leads, but there’s no doubting them in the chest leads V1-3. The AV interval is long, but constan
