Results of head-to-head comparison of patch-based arrhythmia monitors announced

The American Heart Journal has published the results of a head-to-head comparison of two patch-based arrhythmia monitoring systems. The study, “Comparison of two ambulatory patch ECG monitors: The benefit of the P-wave and signal clarity” concluded that the BardyDx CAM singlechannel patch ambulatory ECG monitor (AEM), designed specifically to enhance P-wave detection, identified significantly more arrhythmias and resulted in better, more informed clinical decision-making over the iRhythm Zio XT patch.

In the prospective time-paired comparative study led by electrophysiologist Robert Rho, 30 patients simultaneously wore a pectorally-placed arrhythmia monitoring patch (iRhythm Technologies, Zio XT patch) and a P-wave centric arrhythmia monitoring patch (Bardy Diagnostics, CAM patch) placed over the sternum with the intent of recording for seven days. At the end of the monitoring period, the patches were removed at the same visit. The outcome measures were to compare diagnostic yield, ECG signal clarity, ease of use and comfort, and, importantly, an assessment of differences in clinical decision-making based upon each device’s rhythm diagnosis.
