Identifying and troubleshooting low-frequency artifacts mimicking atrial flutter caused by deep brain stimulator. HeartRhythm Case Rep. 2021;7(10):683-686. Published 2021 Jul 22. doi:10.1016/j.hrcr.2021.07.001https://hdl.handle.net/1805/32047Electromagnetic interference from deep brain stimulators (DBS) is known to cause high-frequency artifact on some forms of cardiac telemetry.1 Here, we (1) present a unique case in which a DBS caused a low-frequency artifact mimicking typical atrial flutter leading to referral to electrophysiology; (2) demonstrate a method to confirm this; and (3) provide recommendations of how to minimize artifact and work around this interaction in future rhythm monitoring attempts.en-USAttribution-NonCommercial-NoDerivatives 4.0 InternationalAmbulatory monitoringAtrial flutterDeep brain stimulatorParkinson diseaseWearable cardiac devicesArticle
