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（ECG）实时监测与诊断的音频化系统。我们引入了两种新颖的音频化设计：（a）听觉放大镜，一种在运动活动时将重要的节律变化音频化的方法；（b）ST段水声音频化，旨在通过构建一个展示心电图信号异常的声景，以辅助临床医生在诊断过程中的诊断过程，当分析信号偏离正常心电图时。所提出的方法旨在帮助用户在不干扰正常任务执行的情况下，无痕迹地监测自身（或其患者）的心脏信号。使用CardioSounds，用户可以通过听觉反馈来监测重要的心律紊乱（例如心律失常）或由心脏血管阻塞引起的病理状况。
