Reported parameters in Details mode

 

In this mode, the details of 12 leads are reported in addition to the Global mode. These details are given in 
table 6-2.

R Dur [ms] 

Time interval from the beginning to the end of the S wave

 

S Dur [ms] 

Time interval from the beginning to the end of the secondary R wave

 

R’ Dur [ms] 

Time interval from the beginning to the end of the secondary S wave

 

S’ Dur [ms] 

Amplitude of ascending edge of P wave

 

P+ Amp [µV] 

Amplitude of descending edge of P wave

 

P- Amp [µV] 

Amplitude of Q wave

 

Q Amp [µV]

Amplitude of S wave

 

S Amp [µV] 

Amplitude of secondary Rwave

 

R’ Amp [µV] 

Amplitude of secondary S wave

 

S’ Amp [µV] 

Amplitude of QRS complex

 

P2P Amp [µV] 

Amplitude of ascending edge of T wave

 

T+ Amp [µV] 

Amplitude of descending edge of T wave

 

T- Amp [µV] 

Amplitude of ST parameter

 

ST Amp [µV] 

Amplitude of ST parameter in the middle of ST segment 

ST Mid Amp [µV] 

Slope of ST segment 

ST Slope [deg] 

 
 
 

 
 

 
 
 
 
 

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.
