9.2. Obtaining an analysis/diagnosis — the DIAG program
The analysis/diagnosis program obtains a 16-second record of the 12 ECG leads, performs R-
wave averaging, calculates the amplitude and time parameters, and then suggests a suitable
diagnosis.
The record contains the following:
a raw ECG curve as specified under
Setup/Diagnosis/ECG
a typical averaged QRS cycle of the 12 channels
time, amplitude, and axis position parameters for the 12 channels
a 16-second long, single-channel rhythm record (displayed only with a 5 mm/s speed)
The 12 typical, averaged QRS-complexes are analysed based only on the typical beats. Non-
typical QRSs are filtered out by the program. The length of the QRSs is always 880 ms.
Attention!
The device can obtain an analysis only in the 45–175 BPM heart frequency range with all
10 electrodes in place.
If pre-start (
Setup/Printing/Pre-start
) is enabled, 2 seconds of signal prior to pressing the
button will also be analysed and stored. This way it is possible to analyse a signal which has
already been displayed.
Analysis data:
heart rate;
QRS length in ms;
P–Q distance in ms;
Q–T/Q–Tc distance in ms;
P-wave angle in degrees;
QRS angle in degrees;
T-wave angle in degrees;
P+ amplitude, positive and negative P-waves in mV, separately for each of the 12
channels;
Q-wave amplitude, separately for each of the 12 channels;
R and R’-wave amplitude, separately for each of the 12 channels;
S-wave amplitude, separately for each of the 12 channels;
S–T level in mV, separately for each of the 12 channels;
T+ amplitude, positive and negative T-wave, separately for each of the 12 channels;
Qd, Q-wave length in ms, separately for each of the 12 channels.
Appendix I
contains detailed information about the decision categories used by the diagnosis
program.
