Benefits and Risks – Insertable Cardiac Monitors

Fainting (Unexplained)


By looking at your heart rhythms before, during, and after a fainting spell, your doctor may be able to identify whether the cause of your unexplained fainting is heart-related. In fact, studies show that a Reveal Insertable Cardiac Monitor (ICM) may diagnose the cause of infrequent, unexplained fainting spells much more often than conventional testing.1

If a heart rhythm-related cause is found, your doctor may recommend therapy based on the exact cause. If your heart rhythm can be ruled out as a cause of fainting, your doctor can focus on other potential causes of your symptoms.

All surgical procedures carry some risk. As an insertable cardiac monitor is inserted just beneath the skin, there is a slight risk of infection, and/or sensitivity to the cardiac monitor material.
