Diagnostic Performance of Automated Blood Pressure Monitor for Detection of Atrial Fibrillation

Area of Science:

• Cardiology
• Medical Devices
• Diagnostic Tools

Background:

• Atrial fibrillation (AF) is a common cardiac arrhythmia.
• AF complications lead to high morbidity, mortality, and healthcare costs.
• Early detection of AF is crucial for managing patient outcomes.

Purpose of the Study:

• To evaluate the diagnostic accuracy of the Rossmax X5 automated blood pressure monitor for detecting atrial fibrillation.
• To assess the feasibility of using the Rossmax X5 as a screening tool for early AF detection.

Main Methods:

• A prospective study involving 123 patients from cardiology and INR clinics.
• Simultaneous measurement of blood pressure with Rossmax X5 and single-lead ECG.
• Confirmation of irregular rhythm using a 12-lead ECG by a cardiologist.

Main Results:

• Rossmax X5 demonstrated high accuracy (99.3%), sensitivity (100%), and specificity (98.6%) compared to a 12-lead ECG.
• Positive predictive value was 98.1% and negative predictive value was 100%.
• The device effectively identified patients with atrial fibrillation.

Conclusions:

• The Rossmax X5 automated blood pressure monitor is a highly accurate tool for AF detection.
• Its performance supports its recommendation as a clinical screening tool for early identification of atrial fibrillation.
