Article Synopsis
- The study investigates the effectiveness of a single-lead implantable cardioverter-defibrillator (DX ICD) with remote monitoring (RM) in detecting atrial high-rate episodes (AHREs) to prevent strokes in patients with atrial fibrillation (AF).
- Based on data from the MATRIX registry involving 1,841 patients, the positive predictive values (PPVs) for accurately detecting true atrial arrhythmia were very high, reaching up to 100% for episodes longer than 24 hours.
- The study found that 8.2% of patients without a prior AF history developed new-onset AF, with many remaining unmedicated and at high risk for stroke, highlighting the importance of regular monitoring and timely
Background: The efficacy of dual-chamber cardiac pacing in neuro-mediated reflex syncope with a cardio-inhibitory response to the Tilt-Table test (TT) has not been definitively assessed so far. The lack of reproducibility of results from previous studies may be partially explained by discrepancies in subject selection and some weaknesses in design and methods. The European Society of Cardiology (ESC) has set a class IIb indication to pacemaker implantation in this population recommending further research.

In the past, when devices were much less reliable, DFT testing seemed prudent; however, modern ICD systems have such a high rate of successful defibrillation that many electrophysiologists now question whether DFT testing is still worthwhile, particularly since DFT testing may now be the highest acute risk component of ICD implantation.
Objective: The purpose of this study was to systematically document complications directly attributable to intraoperative DFT testing.
