Chapter 6: ECG analysis and measurement
42
General information
In order to automatically analyze the ECG signal, the analysis and interpretation software of the University
of Glasgow (The Glasgow Program) has been added to DENA 650. This software helps in more accurate
diagnosis of the disease in two parts: Measurement and Interpretation. The Measurement section measures
and reports the important parameters of the ECG signal and the Interpretation section uses the results of the
Measurement section to diagnose the disease.
For best results, the physician must enter the patient's gender and age. It should be noted that the Glasgow
software analyzes and interprets 10 seconds of the ECG signal.
Reported parameters in Global mode
In Global mode, reported signal specifications, are not dependent on individual ECG leads and are generally
calculated for the ECG signal.
