What evidence is there to suggest that AHREs with a duration greater than 5 to 6 minutes are common in patients implanted with CIEDs?
The ASSERT study found that subclinical atrial tachyarrhythmias with at least 6 min duration were detected within 3 months in approximately 10% of patients implanted with a CIED. During a follow-up period of 2.5 years, additional subclinical atrial tachyarrhythmias occurred in approximately 25% of patients, and around 16% of those who had subclinical atrial tachyarrhythmias developed symptomatic AF. Additionally, data from the literature reported in e-Table 20 indicates that AHREs with a duration greater than 5 to 6 minutes are common in patients implanted with CIEDs.
