Abstract

Cardiovascular Disease (CVD) adalah suatu penyakit yang berhubungan dengan jantung dan pembuluh darah. Kegiatan pemantauan aktivitas jantung sangat penting untuk dilakukan sebagai tindakan pencegahan awal dari CVD. Elektrokardiografi (ECG) menjadi salah satu pemantauan aktivitas jantung yang paling umum digunakan saat ini. Informasi aktivitas jantung dapat dilengkapi dengan metode seismokardiografi (SCG) sebagai pemantauan aktivitas dari segi mekanis jantung. ECG dan SCG tidak dapat digunakan secara kontinu karena keterbatasannya dan tidak dapat digunakan saat proses MRI karena medan elektromagnetik dapat mengganggu pembacaan dari kedua sensor tersebut. Pada saat proses MRI perlu dilakukan pemantauan aktivitas jantung untuk mencegah pasien mengalami hioerventilasi ataupun gejala panik pada saat proses MRI berlangsung. Penggunaan sensor fiber optik SMS memiliki beberapa kelebihan, yaitu pembuatannya yang mudah dan murah serta imun terhadap interferensi elektromagnetik. Penelitian ini membuat seismokardiograf berbasis sensor fiber optik SMS. Hasil penelitian menunjukkan sensor fiber optik dengan penyusun multimode fiber step index memiliki sensitivitas sebesar 0,975 dan koefisien determinasi (R2) sebesar 99,99%. Seismokardiograf sensor fiber optik SMS telah divalidasi dengan accelerometer dan elektrokardiograf. Akurasi seismokardiograf dalam menghitung waktu sistol-diastol jantung telah dibandingkan terhaadap ECG sebesar 90,89%.

Cardiovascular Disease (CVD) is a disease related to the heart and blood vessels. Electrocardiography (ECG) is one of the most commonly used monitoring of heart activity today. Information on cardiac activity can be complemented by the seismocardiography (SCG) method as activity monitoring in terms of cardiac mechanics. ECG and SCG cannot be used continuously because of their limitations and cannot be used during the MRI process because the electromagnetic field can interfere with the readings from the two sensors. During the MRI process, it is necessary to monitor cardiac activity to prevent the patient from experiencing hyperventilation or panic symptoms during the MRI process. SMS fiber optic sensors are easy and inexpensive to manufacture and are immune to electromagnetic interference, among other benefits. The goal of this study was to develop a SCG using an SMS fiber optic sensor. The findings demonstrated that the step index multimode fiber optic sensor has a sensitivity of 0.975 and coefficient of determination (R2) of 99.99 percent. Accelerometer and electrocardiograph data have been used to validate the SMS fiber optic sensor SCG. The accuracy of SCG in determining cardiac systolic-diastolic time has been compared to the ECG at 90.89%.
