“…Another question is whether these findings are unique to the St. Jude Autocapture™ algorithm. Indeed, both of our cases and the case reported by Sweeney et al . were with St. Jude pacemakers.…”

“…These two cases illustrate that the Autocapture™ algorithm, under specific circumstances, may initiate VT. Added to the previously published report, these observations should raise awareness among clinicians that, despite the potential benefits of the Autocapture™ feature in St. Jude Medical pacemakers, it may in addition have potential deleterious effect.…”

“…In each of the three cases, including the one by Sweeney et al., an undersensed PVC triggered ventricular arrhythmias. Thus, potential solutions include increasing ventricular sensitivity or medical therapy to suppress PVCs.…”

“…The underlying explanation for this observation is at best speculative. While it is possible that these events are merely identical coincidences, they could also be related to the increased excitability of the ventricular myocardium noted after closely coupled VP …”

“…This is due to the fact that sensing is deactivated in this mode and intrinsic rhythm cannot inhibit PM activity. PM stimuli falling in the vulnerable period of the cardiac cycle could then trigger arrhythmia [11]. On the other hand deactivation of the PM in patients with normal HR under resting conditions could result in bradycardia or asystole under adenosine administration [12].…”

Background: Cardiovascular Magnetic Resonance (CMR) imaging with adenosine stress is an important diagnostic tool in patients with known or suspected coronary artery disease (CAD). However, the method is not yet established for CAD patients with pacemakers (PM) in clinical practice. A possible reason is that no recommendations exist for PM setting (paused pacing or asynchronous mode) during adenosine stress. We elaborated a protocol for rhythm management in clinical routine for PM patients that considers heart rate changes under adenosine using a test infusion of adenosine in selected patients. Methods: 47 consecutive patients (mean age 72.3 ± 10,0 years) with MR conditional PM and known or suspected CAD who underwent CMR in clinical routine were studied in this prospective observational study. PM indications were sinus node dysfunction (SND, n = 19; 40,4%), atrioventricular (AV) block (n = 26; 55.3%) and bradyarrhythmia in permanent atrial fibrillation (AF, n = 2; 4.3%). In patients with SND, normal AV-conduction and resting HR >45 bpm at the time of CMR and in AF the PM was deactivated for the scan. In intermittent AV-block a test infusion of adenosine was given prior to the scan. All patients with permanent higher degree sinuatrial or AV-block or deterioration of AV-conduction in the adenosine test were paced asynchronously during CMR, in patients with preserved AV-conduction under adenosine the pacemaker was deactivated. CMR protocol included cine imaging, adenosine stress perfusion and late gadolinium enhancement. Results: The adenosine test was able to differentiate between mandatory PM stimulation during CMR and safe deactivation of the device. In patients with permanent sinuatrial or AV-block (n = 11; 23.4%) or deterioration of AV conduction in the adenosine test (n = 5, 10.6%) asynchronous pacing above resting heart rate did not interfere with intrinsic rhythm, no competitive stimulation was seen during the scan. 10 of 15 (66,7%) patients with intermittent AV-block showed preserved AV-conduction under adenosine. As in SND and AF deactivation of the PM showed to be safe during CMR, no bradycardia was observed.
