Extending Holter monitoring to 7 days resulted in a 2.57-fold increase in the detection of low-burden (<10%) paroxysmal atrial fibrillation compared to standard 24-hour monitoring.

Does 7-day Holter monitoring improve the detection of low-burden paroxysmal atrial fibrillation compared to 24-hour monitoring?
7-day Holter monitoring substantially improves the detection of low-burden paroxysmal atrial fibrillation, which is frequently missed by standard 24-hour monitoring.
Effect estimate: 2.57-fold increase
Background: Atrial fibrillation (AF) burden and longest duration are important predictors of heart failure and embolism. However, burden-specific detection rates on 7-day Holter ECG remain unclear.
Inoue et al. (Thu,) conducted a cohort in Atrial fibrillation (n=25,817). 7-day Holter monitoring vs. 24-hour Holter monitoring was evaluated on Detection of paroxysmal atrial fibrillation with <10% burden (2.57-fold increase). Extending Holter monitoring to 7 days resulted in a 2.57-fold increase in the detection of low-burden (<10%) paroxysmal atrial fibrillation compared to standard 24-hour monitoring.
