Diagnostic yield of asymptomatic arrhythmias detected by mobile cardiac outpatient telemetry and autotrigger looping event cardiac monitors
Early long‐term external cardiac monitoring devices were able to detect only symptomatic arrhythmias, with patient input required to initiate recording of these events. Recognition of the clinical importance of asymptomatic arrhythmias promoted the development of monitoring devices with automatic (i.e., autotrigger) arrhythmia detection capabilities. Despite the widespread use of mobile cardiac outpatient telemetry (MCOT™) and autotrigger looping event recorders (AT‐LERs) without wireless connectivity capability (AT‐LER) to detect asymptomatic cardiac arrhythmias, little information is available comparing their diagnostic yields. While both the MCOT™ and AT‐LER devices share autotrigger capabilities, the diagnostic algorithms used by the devices are different. In this study we sought to compare the diagnostic accuracy of the MCOT and the AT‐LER devices to detect asymptomatic (i.e., autotrigger) events using a large proprietary monitoring database.
