Implantable cardiac monitors
Syncope (fainting) is a leading cause of hospital emergency visits. In almost 10% of patients, syncope has a cardiac cause; in 50%, a non-cardiac cause, and in 40% the cause of syncope is unknown. Syncope is difficult to diagnose as syncopal episodes are often too infrequent and unpredictable for detection with conventional monitoring techniques.
