Heart Monitor (Insertable)

Some causes of unexplained fainting are harmless and can be treated with simple lifestyle changes. Others are more serious. An implantable heart (cardiac) monitor records your heart’s activity over long periods of time. This may help your doctor determine if an abnormal heart rhythm is the cause of your fainting.

For Unexplained Fainting

Fainting, also called syncope, is a sudden loss of consciousness. It occurs when blood pressure drops and not enough oxygen reaches the brain. When fainting is unexplained and infrequent, an insertable cardiac monitor may be prescribed. The small, implantable monitor continuously records your heart's activity. When you faint, your doctor can download information from the monitor to determine if the cause is heart-related.
