Assessment of the Utility of BIOMONITOR to Identify Atrial Fibrillation (AF) in Ablation Candidates Using Precise AF Detection

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the diagnostic utility of BIOTRONIK's subcutaneous cardiac rhythm monitor for the detection of AF prior to an ablation procedure.

Detailed Description
-----------------
BIO-Precision is a post-market study investigating the utility of atrial fibrillation (AF) detection using BIOTRONIK's subcutaneous cardiac rhythm monitor, BIOMONITOR. The purpose of this study is to evaluate the diagnostic utility of BIOTRONIK's BIOMONITOR for the detection and confirmation of AF prior to an ablation procedure. Study population includes patients with paroxysmal AF being evaluated for an AF ablation. Holter monitoring for 48 hours will be performed after insertion of the BIOMONITOR but prior to AF ablation. This study will enroll up to 100 subjects, to obtain 60 usable Holter recordings, at 5 study sites within the United States (U.S.). Study subjects will be followed for three months after the completion of a 48 hr Holter monitor.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Diagnostic Sensitivity | The diagnostic sensitivity of the BIOMONITOR will be determined by comparing AF events detected by the BIOMONITOR and 48 hr Holter monitor for each subject. Diagnostic sensitivity is the ability of the BIOMONITOR to correctly identify subjects who have true AF as determined by the Holter monitor. It is calculated as the number of participants with a true BIOMONITOR AF detection divided by the sum of the number of participants with a true BIOMONITOR AF detection and the number of participants with a false negative BIOMONITOR AF detection. | 48 hours |
