Monitoring Your Heart Rhythms

If you or a loved one has symptoms such as fainting, shortness of breath or a racing heart, your health care team may recommend a heart monitor like the LUX-Dx Insertable Cardiac Monitor (ICM) System. This Insertable Cardiac Monitor monitors your heart rhythms and sends valuable information to your health care team so they can provide the best care.
