Features & Capabilities

The Abbott Insertable Cardiac Monitor (ICM) is a slim device that continuously monitors heart rhythm and records events as configured by your doctor. The myMerlin™ app securely transmits this information on a doctor-defined schedule and provides a user-friendly way to record symptomatic events, view past and upcoming transmissions, and stay connected with your clinician.

Note: The app will only function when paired with an Abbott ICM implant (prescription required). Some ICM models support remote updates to monitoring settings by a healthcare provider. The app does not provide health services or medical advice; contact your healthcare provider with any medical concerns.

User Reviews

Reviews show a mixed experience. Some users find myMerlin easy to use and helpful for recording symptoms for doctors, with night-time transmissions working and newer hardware offering longer battery life. However, many reports focus on reliability: the app crashes frequently; pairing the loop recorder is unreliable, sometimes failing after iOS updates; manual symptom logging is limited or removed; transmission status is unclear as histories can be blank; and the startup sound is disruptive and cannot be silenced. Overall, reliability and data transparency are the main concerns.
Pros
  • Easy to use and helpful for recording symptoms for doctors
  • Night-time data transmissions can work well, aiding monitoring
  • Some users report the app works as needed and supports their monitoring setup
  • Newer hardware reportedly offers longer battery life, improving use
  • Overall, when functioning, the app provides useful symptom logging and monitoring support
Cons
  • Frequent crashes or random closures, causing interruptions and frustration
  • Unreliable pairing/connection with the loop recorder and issues after iOS updates
  • Limited or removed manual symptom logging options, hindering clinician review
  • Unclear data transmission status with histories sometimes showing as blank
  • Disruptive startup sound/jingle that cannot be silenced in normal use

Updated: can’t even get the app to get past the logo screen today! $10k surgery to get an ILR, and then everything depends on this lousy app to get the data from it. Or not. Clinic calling me telling me they not getting the data. How often should the mymerlin app show that it is interacting with the ILR? You can see the history list is blank even though it says it will show clinic transmissions. I would assume that means when the app transmits data to the clinic, but who now’s. No way for me to tell. Lousy UI design to give no way to show it is properly linked and sending the data my physician wants. Makes me think I need to waste a bunch of time on the phone with the clinic, or their tech support, neither of which probably can answer any real questions, then waiting for a callback for who knows how long from the clinic that will inevitably come when I am busy or can’t take the call. This lack of proper communication from the app and reassurance of proper operation is so inconsiderate of the patient. There needs to be a class action lawsuit against them for causing unnecessary anxiety, anguish, and distress to the patients.

Just junk. Doesn’t connect can’t find the device serial number and birthdate say invalid. Glad I got my chest cut open to have sub standard junk put in that I had to pay an arm and leg for.

There are a VERY limited array of symptoms that can be entered during an episode. Those offered are very often not very descriptive of the symptoms being experienced. If there was an additional block to enter a more accurate description of the episode it would go a very long way in improving this app. Also it can take up to twenty minutes for the app to download the information from the implant. During this time you cannot use the phone or the app will reset and not record the episode.
