Lumax Technical Manual 147
The patient must be monitored when asynchronous pacing
modes are used. The asynchronous modes V00 and D00 can
only be set if tachyarrhythmia sensing is deactivated. However,
this would leave the patient without sensing and therefore without
ICD therapy. Thus, during the use of asynchronous modes:
- Continually monitor the patient.
- Keep an external defibrillator ready.
2.11.18 Far-Field IEGM for Threshold Testing
(Leadless ECG)
The Lumax 700/740 and 600/640 models offer a new feature,
leadless ECG, which allows for an alternative to ECG and IEGM
for the threshold testing without the external/surface ECG leads.
The Far-Field IEGM can be used to replace surface ECG leads
during threshold testing. There is now an option to select between
(near-field) IEGM, conventional surface ECG signals (I, II, or III)
or leadless ECG (FF IEGM) as display options automatically. The
figure below shows FF option:
2.11.19 Advanced AT/AF Diagnostics (Lumax
700/740 only)
The Lumax 700/740 models offer the ability to record longer pre-
history of atrial episodes (AT/AF events). This feature has been
doubled from 30 seconds to > 1 minute. This feature is important
in terms of genesis evaluation of atrial tachyarrhythmias.
