Abstract
CardioSounds is a portable system that allows users to measure
and sonify their electrocardiogram signal in real-time. The
ECG signal is acquired using the hardware platform BITalino and
subsequently analyzed and sonified using a Raspberry Pi. Users
can control basic features from the system (start recording, stop
recording) using their smartphone. The system is meant to be used
for diagnostic and monitoring of cardiac pathologies, providing
users with the possibility to monitor a signal without occupying
their visual attention. In this paper, we introduce a novel method,
anticipatory mapping, to sonify rhythm disturbances such as Atrial
Fibrillation, Atrial flutter and Ventricular Fibrillation. Anticipatory
mapping enhances perception of rhythmic details without disrupting
the direct perception of the actual heart beat rhythm. We
test the method on selected pathological data involving three of the
most known rhythm disturbances. A preliminary perception test to
assess aesthetics of the sonifications and its possible use in medical
scenarios shows that the anticipatory mapping method is regarded
as informative discerning healthy and pathological states, however
there is no agreement about a preferred sonification type.
