1 Medical procedure and EMI warnings, precautions, and guidance

1.1 Introduction

This manual is intended for physicians and other health care professionals who treat patients who have a
Medtronic LINQ II insertable cardiac monitor. To view this manual online or to download it, refer to the Medtronic
Manual Library at www.medtronic.com/manuals.

The “Warnings, precautions, and guidance for clinicians performing medical procedures” section of this document
is useful to health care professionals who perform medical procedures on patients with Medtronic insertable
cardiac monitor systems and who consult with the patients’ cardiologists. This section provides warnings,
precautions, and guidance related to medical therapies and diagnostic procedures that may cause serious injury
to a LINQ II patient, interfere with a LINQ II insertable cardiac monitor (device), or permanently damage the device.

The “Warnings, precautions, and guidance related to electromagnetic interference (EMI)” section of this document
provides precautions and other information related to electromagnetic interference (EMI) that is helpful to patients
in their daily living. Health care professionals can review the information with their patients and use it as a reference
for post-procedure consultations.

For guidance on unusual or new medical procedures or potential EMI scenarios you are concerned about when
treating LINQ II patients that are not addressed in this manual, contact Medtronic as follows:

●

In the United States, contact a Medtronic representative or Medtronic Technical Services at
[e-mail] or [phone].

●

Outside the United States, contact a Medtronic representative.

Caution regarding concomitant device implants: – If the LINQ II patient has an implanted pacemaker or
defibrillator, the automatic detection of arrhythmia episodes in the LINQ II device may be affected by the paced
heart rhythm. To minimize the possibility of a Medtronic programmer’s programming head and telemetry interfering
with a pacemaker or defibrillator, do not hold either the Patient Assistant activator or the programming head directly
above an implanted device that was not manufactured by Medtronic while the programmer application is active.

1.2 Warnings, precautions, and guidance for clinicians performing medical procedures on LINQ II patients

The influence of medical equipment on LINQ II device performance varies considerably according to the type of
unit and energy levels employed. In situations where risks are known, the LINQ II device should be interrogated in
order to save the device data before medical procedures that may affect device data are performed. After the
medical procedure and at the patient’s and clinician’s earliest convenience, the patient’s LINQ II device should be
checked for proper function.

The following subsections provide warnings, precautions, and guidance for health care providers that perform the
specified medical procedures on LINQ II patients.

1.2.1 Ablation (RF ablation or microwave ablation)

Ablation is a surgical technique in which radiofrequency (RF) or microwave energy is used to destroy cells by
creating heat. Ablation may temporarily affect LINQ II device data collection, cause device electrical reset, or
damage the device. To avoid such effects, observe the following precautions:

●

The ablation equipment should not directly contact the LINQ II device.

●

Use short, intermittent, and irregular bursts at the lowest clinically appropriate energy levels.

If an electrical reset occurs, the patient’s LINQ II device health care provider should reprogram device parameters
as needed.
