Atrial Pacemaker Captures During 2:1 AV Block
Report: Sinus rhythm 0.5 AV sequential (known DDD) pacemaker 0.5 Atrial sensing & pacing 1.0”escape interval 1 AV interval 0.30” atrial-paced beats and one conducted sinus beat 1 Failed ventricular pacing 1 Second degree AV block 2:1 alternate paced
No Pacing and 2:1 Failure to Sense
Report:Sinus rhythm 55/min 1 Demand pacemaker: failure to pace 2 2:1 failure to sense 5 LVH voltage (SV2 25mm) 0.5 Left atrial abnormality (LAA) 0.5 Old inferior infarct 0.5 Possible old anterior infarct (loss of R height from V2 to V3) 0.5 Commen
VEBs in Bigeminy
Report: Sinus rhythm 67 – 71/min 1 Ventricular pacemaker 1 VVI mode 4 Ventricular fusion beats 2 VEBs 1 Bigeminal 0.5 Uniform 0.5 Comment: The interesting question is whether the atrial deflections following VEBs are blocked sinus P waves or retrog
Paced Escape - Paced Capture Bigeminy
Report:Sinus rhythm 57/min 0.5 Complete AV dissociation 0.5 Fixed pacemaker rhythm 31/min 3 Demand pacemaker escape rhythm (set at) 60/min 3 Escape-capture bigeminy 3 Comment:The original pacemaker continued to fire at 31/min as before, obviously dev
Un Unusual Morphology
Report:Sequential AV pacemaker (known ICD) rhythm 59/min 2 Composite (? Fusion) QRS morphology 8 Comment: The ventricular complexes start as expected, with an initial slur of myocardial activation lasting approximately 0.08”. The second half of each co
Right Atrial Abnormality
Report: Sinus rhythm Right atrial abnormality Comment: The P wave is over 2.5 mm tall . It is characteristically peaked, and its axis is over +70o; these additional criteria are not necessary for the diagnosis of RAA. The older term, P pulmonale, is st
Pacing Illusion
Report:Sinus rhythm 1 First degree AV block (PR 0.28”) 2 Atrial-sensing pacemaker – no captures 5 Incomplete LBBB (LVH with ST/T changes) 2 Comment:The illusion of pacing is, of course, supported by the patient’s native incomplete LBBB and its left ax
Trigeminy
Report: Demand pacemaker rhythm 65/min 2 Hysteresis rate 60/min 3 Intermittent retrograde conduction 2 Sinus capture beats 2 Trigeminy 1 Probable sick sinus syndrome 0 Comment: To comment on the appropriateness of the pacing rate one has to know th
Controlling the Ventricular Rate: PVARP
Report:Atrial tachycardia 222/min (? slow flutter) with 2:1 block 4 LVH with ST/T changes (incomplete LBBB) 1 Atrial-sensing electronic pacemaker firing 111/min 1 Pseudofusion beats 4 Comment:The atrial tachycardia is somewhat discreet, but two atrial
DDD Pacemaker: Fractured Ventricular Lead
Report:Dual AV pacing 99/min 1 No ventricular capture, atrial 100% pacing 7 Right bundle branch block 2 Comment:The patient arrived to Casualty in sinus rhythm with sinus pauses and both escape and premature SVEBs (Fig 114a). He still had the SSS. The
