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

## TL;DR

This study shows that the Rossmax X5 blood pressure monitor can accurately detect atrial fibrillation, making it a useful tool for early diagnosis.

## Contribution

The study demonstrates the high diagnostic accuracy of an automated blood pressure monitor for detecting atrial fibrillation in a clinical setting.

## Key findings

- The Rossmax X5 achieved 99.3% accuracy in detecting atrial fibrillation compared to 12-lead ECG.
- It had 100% sensitivity and 98.6% specificity for AF detection.
- The positive and negative predictive values were 98.1% and 100%, respectively.

## Abstract

Background

Atrial fibrillation (AF) is a type of heart disease characterized by an irregular cardiac rhythm. The complications of AF are associated with significant morbidity, mortality, and medical expenses. This emphasizes the significance of detecting AF early using a feasible device.

Methods

A total of 123 patients who attended cardiology and INR clinics were enrolled, with 51 of them having AF. The blood pressure of all patients was measured three times using the Rossmax X5, while a single-lead electrocardiogram (ECG) was monitored simultaneously. Following that, a 12-lead ECG was performed on all patients. A cardiologist confirmed the irregular rhythm.

Results

Compared to the 12-lead ECG method, Rossmax X5 has an accuracy of 99.3%, a sensitivity of 100%, and a specificity of 98.6%. The positive and negative predictive values were also significant, which were 98.1% and 100%, respectively.

Conclusion

The Rossmax X5 automated blood pressure monitor has a high detection accuracy for AF. Therefore, Rossmax X5 can be recommended for use in the clinical setting as a screening tool for early AF detection.
