3.1.1

recorder

equipment worn or carried by the patient with the intention of recording and analysing heart action potentials

3.1.2

scanner

equipment that retrieves ECG waveforms from the heart recorder and analyses, edits the information received to determine the presence of abnormal heart rhythms and reports

3.1.3

patient ECG recording event

manual marking of clinical information during ECG recording

Note 1 to entry: There shall be a “patient ECG recording event” switch on the recorder. It can be pushed to mark and timestamp a clinical event affecting the assessment of the ECG waveform. For example, the patient can have chest pain, dizziness or palpitation. Pushing a “patient ECG recording event” switch located on the recorder allows for recording ECG waveforms with the time of occurrence.

3.1.4

dominant beat

primary heart beat extracted from typical beats for each lead in a period of long-term ECG

Note 1 to entry: The dominant beat is used for measurement and analysis of ECG in the period and easily viewing the change of ECGs for each period.

Note 2 to entry: In general, it is the typical heart beat excepting extrasystole or drifts of baseline.

3.1.5

average beat

beat waveform constructed from the average value of each temporal point in ECG across a number of beats

3.1.6

median beat

beat waveform constructed from the median value of each temporal point in ECG across a number of beats

3.1.7

leads off

disconnected electrodes
