What Is Remote Monitoring?

Remote monitoring is a way for you to communicate critical information about your heart’s activities directly to your doctor’s office or clinic at any time of the day, and on any day of the week. In fact, it is a way for your implantable cardiac device, which is a minicomputer, to communicate directly with technology in your doctor’s office, without you having to see your doctor in person. This can reduce your number of hospital or clinic visits and make sure your doctor has information about your heart.

It works when a transmitter syncs with your pacemaker or ICD, collecting data about your heart’s activity, such as its rate and rhythm, as well as data about the device itself. The transmitter then sends that information by way of a secure website to your hospital or clinic for your doctor to interpret. This syncing and transmission can happen overnight, while you sleep.

Remote monitoring benefits

Your safety and convenience are the main benefits of remote monitoring. Remote monitoring can allow your doctor not only to learn about your heart’s activity, but also to see if anything unusual is happening with your device, and decide if action is needed. In this way, remote monitoring can reduce the number of follow-up clinic visits you will need to make to check on your pacemaker or ICD.
