Trial results for a study evaluating the Masimo INVSENSOR00057 in detecting Atrial Fibrillation were posted on ClinicalTrials.gov on 2025-05-22. The device demonstrated a sensitivity of 96.97% and a specificity of 100% in 139 participants.
Background
Atrial Fibrillation (AFib) is a common heart rhythm disorder characterized by irregular and often rapid heartbeats, which can lead to serious complications such as stroke. Timely and accurate detection of AFib is critical for initiating appropriate management and reducing associated risks. Current diagnostic methods often rely on electrocardiograms (ECGs), but continuous or convenient non-invasive monitoring solutions are increasingly sought to improve detection rates, especially for paroxysmal AFib. The development of highly accurate, non-invasive sensors could significantly enhance patient screening and monitoring, allowing for earlier intervention.
Trial design
This completed study, designated as Phase NA, enrolled 139 participants to validate the performance of the Masimo INVSENSOR00057 in detecting Atrial Fibrillation. The trial compared non-invasive ECG measurements from the INVSENSOR00057 to results obtained from an FDA-cleared ECG monitor.
Key results
The trial reported the following key measurements for the INVSENSOR00057 Atrial Fibrillation detection function:
- Sensitivity: 96.97% of true positive.
- Specificity: 100% of true negative.
What this means
The reported high sensitivity and specificity of the Masimo INVSENSOR00057 suggest its potential as an effective non-invasive tool for detecting Atrial Fibrillation. A sensitivity of 96.97% indicates that the sensor is highly capable of correctly identifying individuals who have AFib, while a specificity of 100% suggests it is very accurate in correctly identifying individuals who do not have AFib. These results could have significant implications for improving early diagnosis and monitoring of AFib, potentially leading to better patient outcomes by facilitating timely medical intervention.
