What is the accuracy of AHREs detection by cardiac implanted electronic devices?
AHREs, currently defined as episodes of at least 5 minutes of atrial tachyarrhythmias/AF with an atrial rate >180 beats/min, are usually asymptomatic and discovered during routine device follow-up. The diagnostic accuracy is reliable when episodes $ 5 min in duration are considered, since, using this cutoff, the appropriateness in AF detection is 95%, minimizing the risk of over-sensing due to detection of artifacts caused by myopotentials or other sources of electrical interference.
