LINQ ICM
The LINQ ICM (Medtronic, Inc.) is a small FDA approved cardiac monitor implanted in the subcutaneous tissue of the chest wall that is designed to continuously record a single-lead ECG, monitoring the cardiac rhythm for up to three years. The device records and stores patient's rhythm on two occasions: first when programmed criteria are met and second upon patient activation. These programmable arrhythmia criteria are based on heart rate (bradycardia, tachycardia), irregularity of heart rate and duration of rate disturbance. The LINQ ICM (or future iterations) will be utilized in this study to detect arrhythmias in our study population. The LINQ ICM is approved by the FDA for use in patients where there is a suspicion of occult cardiac arrhythmias and is therefore being utilized in this study in accordance with the FDA labeling.
