What is the evidence that AHREs with a duration of more than 5 to 6 minutes are common in patients implanted with CIEDs?
The ASSERT study revealed that within 3 months, approximately 10% of patients implanted with a CIED had subclinical atrial tachyarrhythmias with at least 6 min duration. Additionally, 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. These findings, along with data from the literature reported in e-Table 20, support the evidence that AHREs with a duration of more than 5 to 6 minutes are common in patients implanted with CIEDs.
