Table 8.

Comparison of different ECG digitisation tools: Existing digitisation tools are specific ECG configurations or do not detect ECG anchor points by automated methods.

By contrast, the automated tool presented here in can digitise ECGs of any configuration. (‘–’ suggests that it is unclear if the algorithm can process ECG configuration).
