Loop Recorder Implantation
A loop recorder is a tiny heart monitor placed just under the skin in a short outpatient procedure performed here at the center. It continuously watches for irregular rhythms and helps diagnose unexplained fainting, palpitations, or stroke causes.

Overview
An implantable loop recorder is a monitor about the size of a paperclip placed just under the skin of the chest. It records your heart rhythm continuously for up to three years.
It is the most reliable way to catch infrequent events such as unexplained fainting, palpitations, or silent atrial fibrillation after a stroke.
Is this right for me?
Candidacy is confirmed after a review of your history, imaging, and medications. Patients we most often treat include those with:
- Fainting or near-fainting with no clear cause
- Palpitations that never appear on a short-term monitor
- Stroke of unknown source needing atrial fibrillation screening
- Suspected intermittent arrhythmia
What to expect, step by step
Arrival and preparation
You check in with a coordinator, change into a gown, and meet your nurse. Vitals are taken, an IV is started if needed, and your care team reviews the plan and answers questions with your caregiver present.
Numbing and insertion
A small area of skin is numbed and the recorder is inserted through an incision under a centimeter. No stitches deep to the skin are required.
Pairing the monitor
The device is paired with a bedside or smartphone transmitter that sends data to your care team automatically.
Recovery suite
You rest in a private recovery bay while your nurse monitors vitals and comfort. Written instructions are reviewed with you and your caregiver before discharge.
Home the same day
A caregiver drives you home. A member of our team calls the next business day to check on you and confirm your follow-up appointment.
Recovery
You can shower after 48 hours. There are no activity limits beyond keeping the small incision clean.
Transmissions are reviewed by the monitoring team and you are contacted if a significant rhythm is found.
Risks and what we watch for
Every procedure carries risk. These are the ones we discuss most often for this procedure.
- Bleeding, bruising, or soreness at the access site or incision
- Infection, which is why sterile technique and, when indicated, antibiotics are used
- Reaction to sedation, anesthesia, or contrast dye, monitored continuously by your anesthesia provider
- Incomplete relief of symptoms, or symptoms that return over time
- The need for additional treatment, imaging, or a different procedure
- Rarely, a complication serious enough to require a higher level of care than an outpatient setting provides
We review these with you in detail before you consent, and you can change your mind at any point.

Frequently asked questions
Is it visible?
A faint outline may be seen in thin patients, but the device sits flat and is not noticeable under clothing.
How is it removed?
Removal takes minutes under local anesthetic once monitoring is complete or the battery ends.
Is loop recorder implantation done as an outpatient procedure?
Yes. It is performed at our ACHC-accredited ambulatory surgery center in The Woodlands, minutes from Tomball and Spring, and patients go home the same day with a caregiver.
Will my insurance cover it?
Coverage depends on your specific plan and benefits. Our team verifies your benefits and gives you a written estimate before anything is scheduled.
Do you offer Spanish-speaking support?
Yes. Bilingual English and Spanish coordination is available from your first call through recovery instructions and follow-up.
