Kucher Technical Service Lumax 540 Thoracic Impedance – Possible Parameter Settings Option 1 Option 2 Option 3 Please note: As long as HM is OFF, there is no access to TI Option 4 If HM is ON, TI can be enabled or disabled individually TI (HM) = ON and TI (statistics) = OFF means that the TI-values will only be transmitted via HM and not be stored Inside the ICD. TI (HM) = ON and TI (statistics) = ON means that the TI-values will be transmitted via HM and stored inside the ICD. (The interrogation time during next FU is significantly longer if TI (statistics) is ON)
