Trial Outcomes & Findings for Assessment of the Utility of BIOMONITOR to Identify Atrial Fibrillation (AF) in Ablation Candidates Using Precise AF Detection (NCT NCT04076917)

NCT ID: NCT04076917

Last Updated: 2022-04-05

Results Overview

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.

PRIMARY outcome

Timeframe: 48 hours

Population: Participants with an evaluable Holter recording who have completed the 48 hr Holter monitor

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.
