Supplementary Material for "CardioSounds: Real-time Auditory Assistance for Supporting Cardiac Diagnostic and Monitoring"

This paper presents a real-time sonification system for Electrocardiography (ECG) monitoring and diagnostic. We introduce two novel sonification designs: (a) Auditory magnification loupe, a method to sonify important beat-to-beat variations when doing sports activities, and (b) ST-segment water sonification, which aims to assist clinicians in the diagnostic process by building a soundscape that exhibits ECG signal abnormalities as the analysed signal deviates from a healthy ECG. The proposed methods were designed to assist users to unobtrusively monitor their own (or their patients') heart signal in situations when a visual-only representation is not convenient for the proper fulfilment of a given task. Using CardioSounds users receive auditory feedback in order to monitor important heart rhythm disturbances (e.g. Arrhythmia) or pathologies due to a blocking of the heart's vessels.

本文提出了一种用于心电图（Electrocardiography, ECG）监测与诊断的实时声化系统。本文介绍了两种创新性声化设计方案：其一为听觉放大检视器（Auditory magnification loupe），该方案可在运动场景下对关键逐搏变异进行声化处理；其二为ST段水声化（ST-segment water sonification），其旨在通过构建声景，当分析信号偏离健康心电图时，将心电信号异常以听觉形式呈现，从而辅助临床医生开展诊断工作。本研究所提出的方法旨在帮助用户在仅依赖视觉表征无法便捷完成既定任务的场景中，悄无声息地监测自身（或患者）的心电信号。用户通过使用CardioSounds可获取听觉反馈，以此监测重要的心律异常（如心律失常（Arrhythmia））以及因心脏血管阻塞引发的各类病症。
