It's the ECG's that george rejects that makes George's ECG's the best.
AV Pacemaker: No Ventricular Lead
Report:Atrial pacemaker rhythm 59/min 2 Right bundle branch block 2 AV interval 0.31” ?no ventricular lead 4 Q waves in 1, aVL, V5-6 – possible old anterolateral infarction 2 Comment:The diagnosis is suggested by the unusually long AV interval, althou
RBBB: Paced Fusion Rhythm
Report:Sinus tachycardia 107/min 1 Atrial-sensing ventricular pacemaker, 100% capture 2 Presumptive right bundle branch block 5 Fusion complexes throughout 2 Comment:This is similar to the delectable deduction in Case 38, except that the pacemaker’s
Failed Biventricular Pacemaker
Report:Sinus rhythm 63/min 1 Left atrial abnormality (LAA) 1 P wave 0.16” First degree AV block 3 PR 0.28” Right axis deviation +250o Left bundle branch block 3 Dual pacemaker, failed, 70/min 2 Comment:The combination of LBBB and RAD is virtually
Positive Concordant Precordial Pattern
Report:Pacemaker rhythm 63/min 2 1:1 retrograde conduction 3 Positive concordant precordial pattern 5 Comment:This is a temporary, bipolar unit, inserted in CCU. The patient had a very large right ventricle or the lead is inadvertently placed in the po
Temporary AV Pacemaker
Report:Upper strips: Ventricular lead off Atrial pacemaker rhythm 80/min Loss of capture with reduced output Escape sinus bradycardia Resumption of capture at treshhold output Lower strip: Atrial pacemaker rhythm 53/min Failure to pace in two cycl
Beginning of an Endless Loop
Report: Sinus rhythm 79/min 1 VEB 1 Ventricular escape beat, preceded by attempt at atrial pacemaker escape 1 VEBs, dimorphic couplet 1 Retrograde conduction 2 Retrograde P sensing and generating pacemaker tachycardia 103/min 4 Comment: The retrogra
Atrial-Sensing Pacemaker in AF
Report: Atrial flutter/fibrillation 2 Dual-chamber pacemaker 3 Tachycardia up to 129/min due to atrial (over)sensing 5 Comment: The pacemaker is programmed to follow – up to a set upper rate limit – atrial activity. This is really meant for sinus rhyth
Pacemaker Rhythm and LBBB
Report: Electronic demand pacemaker rhythm 70/min 2 Atrial fibrillation 2 Left bundle branch block (last 3 beats) 6 Comment: If it were not for the rhythm strip, few would notice the transition from pacemaker to supraventricular rhythm at the end of th
Tricuspid Atresia
Report: Atrial pacemaker rhythm 111/min (dual chamber pacemaker) 4 Left axis deviation (LAD) –60o 3 LVH with ST/T changes 3 Comment: A cyanosed child with LAD most likely has tricuspid atresia; in one large series LAD was present in 87% of those wit
Complete AV Dissociation
Report: Pacemaker rhythm 80/min 3 Sinus rhythm, non-conducted, 85/min 3 Complete AV dissociation 3 Left atrial abnormality (LAA) 1 Comment: The paced complexes have the typical LBBB/LAD appearance, indicating pacing from the apex of the right ventricl
