Final answer:
The Zio XT patch is suggested to have a higher diagnostic yield than a Holter monitor, with some studies indicating it may detect significant cardiac arrhythmias up to three times more frequently.
Step-by-step explanation:
The question pertains to the comparative diagnostic yield of Zio XT versus the traditional Holter monitor in the context of cardiac event monitoring. Although specific numbers can vary based upon the study and the populations being tested, some research has suggested that the Zio XT patch can have a higher diagnostic yield than a Holter monitor. One study indicated that Zio XT identified significant cardiac arrhythmias nearly three times more often than a Holter monitor did in a cohort of patients.
It's important to note that the exact figure can differ based on the duration of monitoring, the patient demographics, and the type of arrhythmias being studied.
However, this general trend suggests that Zio XT might offer substantial improvements in detecting irregular heart rhythms compared to the traditional Holter monitor.
