Camm et al showed in a study on patients with arrhythmogenic right ventricular dysplasia (ARVD), that over the total wear time of both devices, the ZIO®XT Patch detected more premature ventricular contraction events than a 24 hour Holter monitor. Barrett et al showed ZIO®XT Patch had a 57% greater diagnostic yield than a 24 hour Holter monitor, and Schreiber at al demonstrated an overall diagnostic yield of 63% in ED patients with indications for monitoring. This study also showed that 48% of patients had ≥1 arrhythmia and 10% were symptomatic at the time of their arrhythmia. Median time to first arrhythmia was 1.0 days (IQR 0.2-2.8) and median time to first symptomatic arrhythmia was 1.5 days (IQR 0.4-6.7). 54% of symptomatic patients did not have any arrhythmia during their triggered events.
