7.3 Temporary Programming
CAUTION
OFF Mode – Use of the OFF mode should be avoided in pacemaker
dependent patients. The OFF mode can be transmitted as a
temporary program only to permit evaluation of the patient’s
spontaneous rhythm.
A temporary program is a pacing program which remains activated while the programming head is
positioned over the pulse generator. Upon removal of the programming head (at least 15 cm away
from the pulse generator), the temporary program will be automatically deactivated and the permanent
program will again be in effect.
Generally, every pacing program displayed on the programmer screen may be transmitted as a
temporary program by pressing the key designated on the programmer keyboard. With few exceptions,
this also applies to pacing programs containing a parameter conict, which cannot be programmed
as permanent programs. Temporary programming facilitates follow-up and enhances patient safety.
Test programs affecting patient safety, like pacing threshold measurements in a pacemaker-dependent
patient, should be activated as a temporary program only.
When interrogating the pulse generator, the permanent program will always be displayed and
documented, even though a temporary program was activated during the interrogation.
During temporary program activation, the rate adaptation, trend monitor, and the event counter are
always inactive.
7.4 Patient Data Memory
Individual patient data can be stored in the pulse generator’s memory. The stored data is automatically
displayed upon each interrogation. The amount of data stored is determined by the software version
being used. The patient data memory contains the following data categories:
• Patient ID (Code)
• Patient Name
• Date of Birth
• Gender
• Symptom
• Etiology
• ECG Indication
• Physician
• Implantation Date
• Lead Polarity (A / RV / LV)
• Lead Mode
• Lead Serial Number
• Lead Manufacturer
• Lead Position
• NYHA Class
• LVEF
• Hospital
• City
WARNING
Unipolar/Bipolar – Evia HF / HF-T can be used with either unipolar
or bipolar IS-1 leads.
If the pacing or sensing function is to be programmed to bipolar,
it must be veried that bipolar leads have been implanted in that
chamber. If either of the leads is unipolar, unipolar sensing and
pacing functions must be programmed in that chamber. Failure to
program the appropriate lead conguration could result in entrance
and/or exit block.
