ECG movement artefacts can be greatly reduced with the aid of a movement absorbing device
Journal Title: Journal of Pre-Clinical and Clinical Research - Year 2007, Vol 1, Issue 1
Abstract
Accurate ECG signal analysis can be confounded by electric lead, and/or electrode movements varying in origin from, for example, hiccups, tremor or patient restlessness. ECG signals recorded using either a conventional electrode holder, or with the aid of an electrode holder capable of absorbing movement artefacts, were measured on a healthy human subject. Results show a greatly improved stability of the ECG signal recorded using an electrode holder capable of absorbing movement artefacts during periods of lead disturbance, and highlight the movement artefacts that develop when the recording lead of a conventional ECG electrode holder is tugged or pulled during the period of monitoring. It is concluded that the new design of ECG electrode holder will not only enable clearer signal recordings for clinical assessment, but will reduce the ECG artefacts associated with the transportation of patients, and may also reduce the time spent by hospital personnel answering ECG alarms that are the result of patient movement.
