It's the ECG's that george rejects that makes George's ECG's the best.
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
Flutter with Failed Pacemaker
Report:Atrial flutter 250/min 2 4:1 block 1 Failed pacemaker 3 Poor R wave progression 1 Nonspecific ST/T changes 1 Comment:The intrinsic pacemaker rate is 70/min – the distance from the tip of the sensed R wave to the first pacing spike and also the
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
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
Allorhythmic Failure to Pace & Sense
Report: Sinus rhythm 59/min 1 First degree AV block 1 Non-specific ST/T changes 1 Demand pacemaker 75/min 2 Trigeminy 1 Intermittent failure to pace 1 Possible intermittent failure to sense 1 Comment: Of every three pacemaker spikes, only one - the
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
