Smallest Implantable Heart Monitor Records Cardiac Rhythms

CREATED Jul 22, 2014

NASHVILLE, Tenn. - A device a fraction of an inch long is providing 83-year-old Thomas Dubois a peace of mind he hasn't had in quite some time.

On Monday, Dubois had a procedure called the Medtronic Reveal LINQ Insertable Cardiac Monitor System at TriStar Summit Medical Center.

The device, also known as a loop recorder, is implanted in the skin above the heart.

It is the smallest implantable heart monitor available that records cardiac rhythms.

“It is watching these electrograms, just like an EKG does at the hospital. It is looking at them continuously,” said Dr. Thomas Williams at TriStar Summit. “So two things can happen: we have preset parameters… so for instance, if the heart rate goes go below 50 or greater than 120, for instance, it would automatically take a snapshot of that and send that to me from the patient’s house. In addition, the patient has an activating wand where he can place that over the device so if he loses consciousness and wants to let us know that’s what happened, so then we can go back and look at the rhythm.”

The implantation process takes about 30 to 45 minutes.

The device can be removed after three years if nothing abnormal is detected.
