Medtronic has announced the first U.S. implant of its Reveal XT Insertable Cardiac Monitor (ICM). The medical device is a way for doctors to monitor patients with heart arrhythmias through the Medtronic Carelink® Network.
The Reveal XT has several advantages over traditional heart monitoring systems. First, many patients report symptoms that cannot be observed clinically, even in tests, because they only occur occasionally or rarely, but still are a cause for concern. The Reveal XT offers a critical tool to diagnose periodic arrhythmias as well as asymptomatic occurrences, such as irregular heart rhythms in the upper chambers of the heart. Also, if a patient is in atrial fibrillation, a doctor can remotely asses what medical treatment is necessary.
Dr. Blair Grubb, professor of Medicine and Pediatrics at the University of Toledo Medical Center, was the first heart specialist to implant the new device.
“I see many patients desperately seeking answers for their unexplained
symptoms,” said Dr. Grubb. “By adding AF detection capabilities and
greater diagnostic reporting, I expect the Reveal XT device to be an
even more effective tool to help monitor and diagnose my patients’
The Reveal XT is implanted in the chest during a short outpatient procedure. If a patient has an episode of irregular heartbeat or other irregular heart occurrence, the device captures an ECG (electrocardiogram) during the episode. The patient stores the ECG in a hand-held device and presses a button to send the ECG to the Medtronic CareLink Network. When the physician accesses the data through the system, she can determine what medical actions need to be taken.
The Reveal XT joins Medtronic's other heart monitoring device, the Reveal DX, which was introduced in the U.S. more than a year ago. Reveal DX is a similar implanted device, but it measures syncope symptoms such as fainting, dizziness and unexplained seizure activity that may be caused by an electrical disturbance in the heart.
