While some people proudly wear their Fitbits to showcase their commitment to fitness, patients with a serious condition may not be so eager to flaunt their connected devices. iRhythm clearly had that in mind when it designed its ZIO XT patch for cardiac monitoring. The wearable device adheres to the chest and can unobtrusively monitor a patient outside of the hospital for up to 14 days. Users can even shower with it. "Nobody knew I was wearing the patch," user Gregory Fisher is quoted as saying on the company's website.

Hear iRhythm's vice president of health policy and payer relations discuss reimbursement trends affecting connected devices at the BIOMEDevice San Jose conference on December 7.
