3 Understanding the ECG
Measurements Program and Report
This section explains how the Agilent M2662A cardiographs measures and
analyzes ECG data.
2Understanding the ECG Analysis Program
The ECG Analysis Program produces precise, accurate and consistent ECG
measurements. The PageWriter 10i cardiograph further provides interpretive
statements which highlight key areas of concern for your review. These tools are
more helpful if you understand how and why they work and how you can best use
their capabilities. Figure 3-1 shows this process.
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 compo-
nents.
3. Measurement - measures each component of the waveform and performs basic
rhythm analysis, producing a comprehensive set of measurements.
