## Sonification Examples for Design 1: Heartbeat-Locked ST Elevation Arpeggio

The supplementary material contains four MP3 files. The six conditions are the following types of STEMI: weak anterior, moderate anterior, severe anterior, weak inferior, moderate inferior, severe inferior.

- S1-1-a-all-six-conditions.mp3
- The selected tones are those of a diatonic sequence [0, 2, 4, 5, 7, 9, 12, 14, 16, 17, 19, 21]
Your browser does not support the audio element.

- S1-1-b-all-six-conditions.mp3,
- using a pentatonic scale [0, 2, 4, 7, 9, 12, 14, 16, 19, 21, 24, 26]
Your browser does not support the audio element.

- S1-2-percussion-all-six-conditions.mp3,
- using low/medium/high pitch for ST below a theta, between -theta and +theta, and above theta.
Your browser does not support the audio element.

- S1-3-vowels-all-six-conditions.mp3.
- ST values (again quantized into three levels—suppressed (below −𝜃), around IE, and elevated (above +𝜃)) are mapped to German vowels: ‘o’ (as in bow), ‘a’ (as in bath), and ‘i’ (as in bee).

## Sonification Examples for Design 3: Grouped Lead Scans

The supplementary material contains 34 MP3 files.

- The first 30 sonification examples (S3.01-S3.30) are in groups of six files (one for each STEMI condition) according to the five modes ‘chromatic’, ‘diatonic’, ‘5- state’, ‘5-state-dissonant’, and ‘tristate’.
