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
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
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
Termination of SVT: Pacemaker Escape
Report:Supraventricular tachycardia 165/min 1 Electrical alternans 2 Termination of paroxysm 0 Atrial escape beat (fusion) 2 Pacemaker escape beat 1 Sinus beat (fusion) 2 VEB (last complex) 1 Nonspecific ST/T changes, possible LVH (R2 = 15 mm) 1
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
Pacemaker-Ventricular Wenckebach
Report: Sinus rhythm 1 Third degree AV block 3 Pacemaker rhythm 2 Möbitz 1 (Wenckebach) pacemaker-ventricular block 4 Comment: There is an allorhythmic succession of 2:1 and 3:2 sequences. The latter show well-marked prolongation of spike-to-QRS inter
Triple Hæmodynamic Handicap
Report:Upper strip: Dual pacemaker rhythm 89/min 1 Ventricular pacing, no atrial capture 1 1:1 retrograde (ventriculo-atrial) conduction 1 SVEB, blocked 3 Atrial capture by the atrial lead following the SVEB 1 Lower strip: Dual pacemaker rhythm 89
Slowing Rate with Battery Depletion
Report:Atrial fibrillation 1 Pacemaker rhythm 60/min 2 Possible battery depletion 7 Comment:Battery depletion is usually programmed to manifest itself by slowing to a pre-set rate, in this case 60/min. This patient’s potential problem was in fact dia
Ventricular Tachycardia in a Patient with Permanent Pacemaker
Report: Ventricular tachycardia 154/min ?Retrograde VA conduction Comment: The QRS is a monophasic R wave in V1, just over 0.16â long: both the morphology and the QRS duration support the diagnosis of VT. The duration criterion is > 0.14â for V1 pos
