Reported Parameters In Global; Reported Parameters In Details - Saadat Dena User Manual

Chapter 6: ECG analysis and measurement
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 the Dena electrocardiograph. 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.
To use this feature, the doctor needs to enter the patient's gender and age. It should be noted that the
Glasgow software analyzes and interprets 10 seconds of the ECG signal.
Then, by selecting one of the two modes Global or Detail and recording the results, it will be printed as
a table at the end of the record paper. The difference between Global and Detail modes is in the detailed
expression of the ECG signal parameters (Measurement section) and the results of the Interpretation
section are exactly the same in both cases.

Reported parameters in Global

ECG Parameters
P Duration [ms]
PR Interval [ms]
QRS Duration [ms]
RR Interval [ms]
QT Interval [ms]
QTc Interval [ms]
T Duration [ms]
ST Duration [ms]
P/QRS/T/ST Axis [degree]
Heart Rate [bpm]
In Global mode, reported signal specifications, are not dependent on individual ECG leads and are
generally calculated for the ECG signal.

Reported parameters in Details

In this mode, the details of 12 leads are reported in addition to the Global mode. These details are
given in table 6-2.
The units for time parameters and amplitude parameters, are millisecond [ms] and microvolt
[µV], respectively.
If the patient has Pacemaker, it is necessary to turn on the Pace Detect.
Glasgow Analysis Software is merely a diagnostic aid software, and for treatment measures, it
is essential that the specialist doctor make a definite statement about the patient's condition.
