Key result
ILRs detect AF with high accuracy vs Holter monitoring, yielding ~82% sensitivity.
Why the study?
Implantable loop recorders enhance AF detection, but their accuracy, particularly the positive predictive value, remains controversial.
Does an implantable loop recorder accurately detect atrial fibrillation compared to Holter monitoring in patients after atrial fibrillation catheter ablation?
Observational (n=13)

p-value: p=<0.001
Implantable loop recorders provide high positive predictive value and specificity for detecting atrial fibrillation after ablation, though sensitivity is moderate and atrial tachycardia detection is limited.
No takes yet. Share an insight, caveat, or question.
ILRs may aid post-ablation AF confirmation via high specificity; leaves open need for randomized validation of moderate sensitivity.
Cho et al. (2020) conducted an observational in Atrial fibrillation post-catheter ablation (n=13). Implantable loop recorders vs. Holter monitoring was evaluated on Accuracy of detecting atrial fibrillation (p=<0.001). Implantable loop recorders demonstrated high accuracy for detecting atrial fibrillation compared to Holter monitoring, with a sensitivity of 81.6%, specificity of 99.9%, and PPV of 99.5%.
