Single Failure to Capture
Report:Sinus rhythm 63/min 2 Complete AV dissociation 4 Pacemaker rhythm 80/min 2 Single failure to pace 4 Comment:AV block cannot be accurately diagnosed here: the atrial (sinus) rate is too slow and the ventricular (pacemaker) rate too fast. Just be
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
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
AV Dissociation with Interference
Report:Sinus rhythm 1 Borderline right atrial abnormality (RAA) 1 SVEB 1 Ventricular demand pacemaker rhythm 72/min 2 AV dissociation with interference 2 Fusion beat 2 Nonspecific ST/T changes 1 Comment:The sinus P waves march through the first fo
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
Pacemaker Blues
Report: [Code Blue] Pacemaker rhythm 72/min 1 QRS 0.36” 2 Pacemaker rhythm 72/min 1 QRS 0.20” 2 AV dissociation 2 Accelerated idioventricular rhythm 78-84/min 2 Comment: The QRS complex width - in paced beats, bundle branch blocks, or VEBs - gener
Inferior Infarction: Blocks and Arrhythmias
Report:Sinus tachycardia 122/min Second degree AV block, unspecified Junctional escape beats and rhythm 46/min Non-phasic aberrant conduction Acute inferior infarction Comment:It is said that the presence of 2o AV block in inferior infarction denotes
Agonal Junctional Tachycardia
Report: Sinus bradycardia Junctional tachycardia AV dissociation VEBs, bigeminy (below) Second degree AV block, 2:1 (middle strip) Third degree AV block, ventricular standstill (Agonal) ST segment elevation Comment: The last part of a normal human
Congenital Heart Block
Report: Respiratory and ventriculophasic sinus arrhythmia Right atrial abnormality (RAA) Left atrial abnormality (LAA) Second degree AV block, unspecified Junctional rhythm 65/min AV dissociation with interference Comment: Congenital heart blocks ar
Sinus Rhythm Faster Than Itself
Report: Nonparoxysmal junctional tachycardia (NPJT) 98-100/min Sinus rhythm 94-96/min Left atrial abnormality Sinus capture beats AV dissociation with interference Left ventricular hypertrophy with ST/T changes (incomplete LBBB) Comment: Paradoxical
