DF4/IS-1 lead connection
The device labeling provides information pertaining to possible lead connections
depending on the device type and pertaining to connection assignment:

Note: The device's DF4 connector port may only be used for connecting leads with a
DF4 connector that conform to ISO 27186.
Leads
BIOTRONIK leads are sheathed with biocompatible silicone. They can be flexibly
maneuvered, are stable long-term, and are equipped for active or passive fixation. They
are implanted using a lead introducer set. Some leads are coated with polyurethane
which is known to increase the sliding properties for the lead. Leads with steroids
reduce inflammatory processes. The fractal design of the electrodes provides for low
pacing thresholds. BIOTRONIK provides adapters to connect already implanted leads to
new devices.
Telemetry
Telemetric communication between the device and the programmer can be carried out
following initialization either by applying the programming head (PGH) to the device or
by using radio frequency (RF) telemetry in the programmer. BIOTRONIK calls this func-
®
tion SafeSync
.

Programmer
Implantation and follow-up are performed with BIOTRONIK's portable programmer:
There is one with integrated RF telemetry and one with a separate SafeSync Module.
The programmer is used during implantation to transfer the current device program to
the device. The pacing thresholds can be determined and all tests can be performed
during in-office follow-up. In addition to this, the programmer is used to set mode and
parameter combinations, as well as for interrogation and saving of data from the
device. Leadless ECG, IEGM, markers and functions are displayed simultaneously on
the color display.
Modes
The mode setting depends on the individual diagnosis:

VVE is the NBD code for the antitachycardia mode of the single-chamber, dual-
chamber, and triple-chamber devices:
V
