While some causes of unexplained fainting are harmless, others may be serious. Heart-related causes, including abnormal heart rhythms, are among the most serious causes of fainting.
An insertable cardiac monitor observes the heart’s activity 24 hours a day, 7 days a week, for up to 3 years. Your doctor can use this information to help determine if the cause of your unexplained fainting may be related to an abnormal heart rhythm. Once the doctor has this information, he or she can decide which treatment option is most appropriate for you.
If your doctor suspects a heart condition is causing your fainting, one or several diagnostic tests may be used to gather information about your heart before an insertable cardiac monitor is recommended.
Although many patients benefit from the use of an insertable cardiac monitor, results may vary. Your doctor can help you decide if it’s right for you.
