3-2 Understanding ECG Analysis and the Predictive Instruments Applications
Figure 3-1: The ECG Analysis Program
The analysis process begins with the simultaneous acquisition of the ECG’s
12 conventional leads. It then proceeds through four steps before producing
the interpreted ECG report. These steps are:
1. Quality Monitor—examines the technical quality of each ECG lead.
2. Pattern Recognition—locates and identifies the various waveform com-
ponents.
3. Measurement—measures each component of the waveform and per-
forms basic rhythm analysis, producing a comprehensive set of measure-
ments.
4. Interpretation (PageWriter 300pi only)—uses the extended measure-
ments, with information about the patient such as age and sex, to select
those interpretive statements from the criteria program which summarize
the findings for the ECG.
