It's the ECG's that george rejects that makes George's ECG's the best.
Alternating Paced and Fusion Beats
Report:Slow atrial or junctional rhythm 38/min 2 Ventricular pacemaker rhythm 79/min 2 Superior electrode placement 2 Fusion in alternate beats 2 Presumptive RBBB 1 ST/T changes of uncertain significance 1 Comment:The narrower (0.12 sec) complexes a
Rate Hysteresis
Report:Sinus rhythm 1 VEBs, multiform 2 Demand ventricular pacemaker 3 Rate hysteresis 3 Fusion beat (top panel) 1 Comment:The VVI pacemaker takes over after the VEBs; the long cycle it terminates corresponds to a rate 50/min, while the subsequent t
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
Atrial-Sensing Pacemaker Fails to Pace
Report:V1 and V3 reversed 1 Sinus rhythm 94-100/min 0.5 Ventriculophasic sinus arrhythmia 2 Atrial-sensing ventricular pacemaker 2 Complete failure to pace 1 2:1 and 3:2 AV block, Möbitz 2 2 Right bundle branch block 1 Borderline ST segment depres
Pacemaker-Ventricular 4:3 Block
Report: Sinus rhythm 1 Atrial-sensing ventricular pacemaker 3 Trigeminy due to 4:3 pacemaker-ventricular block 6 Comment:The paced beats show the expected RV apical pacing morphology of LBBB with LAD. The reason for the intermittent failure to pace is
Low-Atrial Pacemaker
Report:Atrial pacemaker rhythm 70/min 2 Retrograde P wave pattern 7 Nonspecific T wave changes 1 Comment:At first I thought the electrode had been inserted into the coronary sinus. It turned out the heart had been paced more conventionally through the
VEB and DDD Pacemaker
Report:Sinus rhythm 73/min 1 VEB 3 Atrial-sensing ventricular pacemaker 4 Atrial-paced beat 2 Comment:Universal (DDD) pacemakers can both sense and pace the atria. The pause created by the VEB is terminated by an atrial-paced P wave and ventricular-pa
The Commonest Cause of a Pause
Report:Sinus tachycardia 100/min 1 Atrial-sensing ventricular pacemaker rhythm 1 Blocked SVEB 6 Left atrial abnormality (LAA) 1 Right bundle branch block 1 Comment:There is a subtle but definite change in the T wave of the last paced beat before the
Holter Monitor: Endless Loop Tachycardia
Report:AV sequential pacemaker rhythm 75/min 1 SVEB, blocked, inhibiting atrial pacemaker 2 Ventricular pacemaker rhythm with 1:1 retrograde conduction 2 Endless loop tachycardia 120/min 3 VEB terminating the endless loop tachycardia 1 AV sequential
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
