How is an insertable cardiac monitor (ICM) different from a smartwatch?
ICMs, or loop recorders, are medical-grade tools for a doctor to monitor someone’s heart if they are at risk of or diagnosed with a heart rhythm condition. ICMs monitor a person’s heart continuously over a long period of time. Their batteries don’t need to be recharged. Patients don’t have to worry about taking them on and off because ICMs sit under the skin.
