Kristjánsdóttir, Ingibjörg Reimarsdóttir, GuÄ‘run Arnar, DavÃÄ‘ O A media player playing in close proximity to an implanted loop recorder may interfere with In the remaining 7 patients, an event was captured and appropriately recognized by the device at least 1 out of 5 times. In one of these patients, a green indicator light on the activator suggested that a patient-triggered event was captured, but loop recorder interrogation did not show a captured event. Telemetry interference with the activator resulted in failure to capture an event in 7 patients. Telemetry interference on the programmer screen, consisting of either high frequency spikes or blanking of the ECG channel was seen in all patients. We made 5 attempts to capture a patient-triggered ECG by depressing the activator switch 5 times while the media player was off or on. We evaluated for telemetry interference between the activator and the implanted device by placing the activator over the device (normal use) and the media player next to it, first turned off and then, on. We tested for telemetry interference on the programmer by first establishing a telemetry link with the loop recorder and then, the media player was placed next to it, first turned off and then, on. All patients had the Reveal Plus (Medtronic, Inc.) implantable loop recorder. Fourteen patients with implantable loop recorders underwent evaluation for interference with a 15 GB third generation iPod (Apple, Inc.) media player. The purpose of this study was to determine if a media player causes interference with implantable loop recorders. Telemetry interference may be important in patients with implantable loop recorders because capturing a patient-triggered ECG requires a telemetry link between a hand-held activator and the implanted device. Media players have been shown to cause telemetry interference with pacemakers. The implantable loop recorder is a useful diagnostic tool for intermittent cardiovascular symptoms because it can automatically record arrhythmias as well as a patient-triggered ECG.
