Key result
Extended 14-day external loop recorder monitoring improved detection of atrial tachyarrhythmia recurrence after AF ablation, with 24-hour monitoring showing only 27.7% relative sensitivity.
Why the study?
Does 14-day extended external auto-triggered loop recorder monitoring improve detection of recurrent atrial tachyarrhythmia compared to 24-hour Holter monitoring in patients after atrial fibrillation ablation?
Observational (n=342)
Does 14-day extended external auto-triggered loop recorder monitoring improve detection of recurrent atrial tachyarrhythmia compared to 24-hour Holter monitoring in patients after atrial fibrillation ablation?
Extended 14-day monitoring with an auto-triggered external loop recorder significantly increases the detection of recurrent, often asymptomatic, atrial tachyarrhythmias after AF ablation compared to standard 24-hour Holter monitoring.
No takes yet. Share an insight, caveat, or question.
May support extended monitoring for post-AF ablation surveillance; leaves open effects on outcomes and need for RCTs.
Takagi et al. (2014) conducted an observational in Atrial fibrillation after ablation (n=342). Extended external auto-trigger loop recorder (ELR) vs. 24-hour Holter monitoring was evaluated on Detection of atrial tachyarrhythmia recurrence. Extended 14-day external loop recorder monitoring improved detection of atrial tachyarrhythmia recurrence after AF ablation, with 24-hour monitoring showing only 27.7% relative sensitivity.
