Automated Feedback Identifies ECG Signal Issues

ECG recordings are often corrupted by noise and artefact. Among the undesirable results, there are many false alarms and many patient recalls.

In order to maintain and improve ECG signal quality, a great deal of attention is paid to factors such as good skin preparation, use of quality electrodes, proper electrode application, good electrode-to-patient contact, artifact elimination and proper lead selection.

In busy testing organizations, the responsibility for ECG monitoring is shared by a large number of clinicians. Therefore, there must be early recognition of patterns that identify those clinicians who have difficulty in consistently acquiring high-quality ECG signals.

TeleMED’s Feedback Tool offers Physicians, who are interpreting ECG tests, the opportunity to quickly comment on signal quality, request a patient recall and submit these comments to a centralized database, all from the same screen that is used for interpretation.

Users who are responsible for monitoring data quality can generate a report showing all instances of feedback and include a notation of the clinician who acquired the data. Here is a sample excerpt:

To add context and greater meaning to the data in this report, the user can sort data to generate secondary reports. The excerpt below shows such a report.
