Delectable Deductive Diagnosis of RBBB/LPHB
Report: Dual chamber pacemaker rhythm 70/min 2 Frontal plane axis –20o 2 Ventricular fusion complexes throughout 3 Probable underlying right bundle branch block with right axis deviation 3 Comment: I make no apologies for the subcontinental flavour of
Two Pacemakers, One Pacing
Report:Sinus rhythm 1 Third degree AV block 1 Ventricular pacemaker rhythm 62/min 4 Failed dual pacemaker 59/min 4 Comment: The two pacemakers and the sinus rhythm are completely dissociated from each other. There is no atrial or ventricular capture
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
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
Iatrogenous 1o AV Block
Report: Sinus rhythm 62/min 1 DDD (universal) pacemaker Atrial-sensing, ventricular-pacing mode 3 Atrial under-sensing in V1-3, with atrial + ventricular paced complex 3 Long A-V interval 0.30” 3 Comment: In programming the A-V sequential pacemakers
AV Pacemaker: No Ventricular Lead
Report:Atrial pacemaker rhythm 59/min 2 Right bundle branch block 2 AV interval 0.31” ?no ventricular lead 4 Q waves in 1, aVL, V5-6 – possible old anterolateral infarction 2 Comment:The diagnosis is suggested by the unusually long AV interval, althou
Atrial Pacemaker: Complete Failure to Sense
Report:Sinus/atrial pacemaker rhythm 58-72/min 5 Atrial pacemaker: failure to sense 3 Borderline low voltage in frontal leads 1 Nonspecific ST/T changes, V2-5, consistent with ischæmia 1 Comment:The atrial pacing rate is much slower than the sinus rhy
Left Ventricular Pacemaker
Report:Atrial flutter 320/min 2 Probable third degree AV block 3 Ventricular pacemaker rhythm 80/min 2 Left ventricular lead 3 Comment:By coincidence, the F wave rate is almost exactly four times the paced QRS rate and the impression is strong of flut
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
Pacemaker Tachycardia with Spike Alternans
Report:AV sequential pacemaker tachycardia 120/min 8 Pacemaker spike alternans 2 Comment:The patient refused to stay in Casualty and went home. He returned several days later, when his pacemaker was “interrogated”. No malfunction was found in this DDDR
