Zio looks to achieve…

Group 6
Create a user-friendly heart monitor that wouldn't disrupt a patient's life.
Conventional monitors are cumbersome. More often than not, patients don't wear them for the prescribed time period.
Group 7
Create a continuous heart monitor that could be worn for up to 14 days.
Conventional monitors can only be worn for up to 48 hours. In many cases, that’s not enough time to get a full picture of the heart.
Group 8
Create a service that would provide continuous, accurate data unseen in the industry.
Data from conventional monitors contains a high degree of noise and interruptions. And it’s often incomplete, resulting in wasted time, costly re-testing and low clinician trust.

"I’ve worn a 24-hour Holter and it was quite a laborious process and it didn’t come to the right diagnosis, the Zio patch was quick and easy and was diagnosed immediately, so much better."
