It's the ECG's that george rejects that makes George's ECG's the best.
Trigeminy
Report: Demand pacemaker rhythm 65/min 2 Hysteresis rate 60/min 3 Intermittent retrograde conduction 2 Sinus capture beats 2 Trigeminy 1 Probable sick sinus syndrome 0 Comment: To comment on the appropriateness of the pacing rate one has to know th
Runaway Pacemaker
Report: Pacemaker tachycardia 180/min 5 Runaway pacemaker 5 Comment: Most modern pacemakers would have a ventricular rate-limiting mechanism to prevent this degree of tachycardia. The trace itself does not offer any clues as to the cause: all one can se
Pacemaker Confusion in Pseudofusion: Transposition of Great Vessels
Report: Sinus tachycardia 110/min 1 Left atrial abnormality (LAA) 1 Indeterminate abnormal axis ±194o 2 Right ventricular hypertrophy 3 Pacemaker sensing spikes (pseudofusion beats) 3 Comment: The spikes occur after the onset of the QRS complex, pr
Escape-Capture Bigeminy in AF
Report: Atrial fibrillation 1 High-grade or complete AV block 1 Junctional rhythm 2 Pacemaker rhythm 1 Escape-capture bigeminy 1 Left anterior hemiblock (LAHB) 1 Right bundle branch block 1 Anteroseptal infarction, age uncertain 1 ST/T changes con
Failure to Pace
Report:Sinus rhythm approximately 75/min 1 AV dissociation 3 Pacemaker rhythm 88/min 4 Intermittent failure to capture (pace) 2 Comment:Large pacemaker spikes march regularly throughout, but the 10th spike is not followed by a QRS. The morphology of
PseudoWenckebach in Ventricular Pacemaker
Report:Sinus tachycardia 122/min. 1 Möbitz 1 AV block, 5:4 and 4:3 conduction. 2 Atrial-sensing ventricular pacemaker (probably a DDD pacemaker). 3 Pseudo-Wenckebach. 4 Comment:The ventricular complexes are all paced and all identical, indicating no a
Atrial Pacemaker Rhythm: Wenckebach Periods
Report:Dowling Dennis Raymond 55 15/4/00 106504Atrial pacemaker rhythm 89/min 2 Second degree AV block, Möbitz 1 5 Left ventricular hypertrophy with ST/T changes 2 Probable old inferior infarction 3 Comment:The spike-to-R interval (equivalent of PR o
Pretend-Sequential Pacemaker
Report:Pacemaker rhythm 60/min 4 Failed atrial capture 5 Possible retrograde conduction 1 Comment:The atrial spikes precede an empty AV interval – there is no evidence of atrial activity. A trace taken 5 months previously (below) was essentially the sa
Pacemaker Syndrome: Paced Bigeminy
Report:Pacemaker rhythm 71/min 1 AV sequential (probably DDD) pacemaker 2 Reentry paced beats of pacemaker origin 5 Bigeminy 1 No evidence of paced atrial capture 1 Comment:The trace should be compared to the previous one, where each atrial pacing sp
Another Paced Bigeminy
Report:Sinus rhythm 88/min 1 AV block, unspecified 1 DDD pacemaker rhythm 62/min 1 Alternating atrial sensing and pacing 2 Failure to sense alternate P waves 2 Atrial trigeminy 1 Ventricular bigeminy 1 Posterior electrode position 1 Comment:The se
