'''HeartLive Buffer Element''' allows real-rime acquisition and buffering signals from the [http://www.heartlive.nl|HearLive sensor]. The signals include ECG, IBI, HRV and a second-order coherence score. The buffered signal data can be used by the signal processing elements in EventIDE. For example, the signal data can be monitored, analyzed or used for neuro-feedback control in experiments. In order to use this element, you must have the HeartLive sensor connected in a network and running. The element is in a beta state.<br><br>
