Abstract

Background: Atrial Fibrillation is one of the heart diseases identified by its uncoordinated of cardiac rhythm. There are lots of causes that can contribute to this condition, especially patients who have chronic rheumatic heart disease and so on. Stroke is one of the identified complications of AF, and it is associated with significant morbidity, mortality and contribute to high medical expenses. This justifies the important to detect AF early. However, most patients with AF are asymptomatic; hence this leads to difficulty in detecting them and treating early. AF traditionally can be detected by manual palpation of pulse and confirmed by 12-lead ECG, but these methods are time-consuming. Automated Blood Pressure Monitor (ABPM) that integrated with the AF algorithm is now recommended as a new method for AF detection. Rossmax X5 is one of the ABPM that has this feature to detect AF. This study is carried out to know the accuracy of Rossmax X5 to detect AF. Methodology: This is a cross-sectional study that carried out in KPP HUSM from June to July 2020 by using Rossmax X5. One hundred twenty-three subjects will be recruited and 51 of them known to have AF. All of the selected patients will undergo BP measurement using Rossmax X5 for three times with concurrent single-lead ECG monitoring. Subsequently, 12-lead ECG will be performed to all patients. All data will be recorded, and abnormal rhythm will be confirmed by a cardiologist. Conclusion: This study has shown that the ABPM, Rossmax X5 has greater accuracy for detection of atrial fibrillation. From the data that we collected, Rossmax X5 has an accuracy of 99.3%, the sensitivity of 100% with a specificity of 98.6%. Its positive and negative predictive values are also significant, which are 98.6% and 100% respectively. Hence, Rossmax X5 can be suggested to be used in our daily clinical practice, especially in Klinik Pakar Perubatan Hospital Universiti Sains Malaysia.
