9.22.2 Lead Surveillance

In order to prevent system malfunctions
(Exit-Block), PACE 203H checks, during
each delivery of a stimulus, whether an
interruption or a short circuit of the
pacing system has occurred.

Warning:

The lead surveillance is en-

abled only if the pacing amplitude is set
greater than or equal to 2.0 V and if the
pulse duration is set to a value greater
than or equal to 0.15 ms.

9.22.2.1 Short Circuit in Pacing
System

A short circuit in the pacing system can
occur, for example, because of defective
insulation. An interruption of the stimu-
lation system can be caused by lead or
cable breakage, or an incorrectly made
connection.
A short circuit will be indicated by the
warning messages

Atrial output short

or

V

entricular output short

(see chapter

9.22.9) located in the lower display.
Each warning message will also be
accompanied by an acoustic warning
signal. Only pressing the key

Unlock /

Lock

will discard the warning messages

for a few seconds, but will reappear if the
failure persists.

9.22.2.2 Interruption in Pacing
System

In case of an interruption of the stimu-
lation circuit – which is defined as 3 suc-
cessive stimulations not properly carried
out – the open lead symbol (see Figure
12) will be shown in the upper display,

with respect to the corresponding atrial
and/or ventricular channel.

Figure 12: Open Lead Symbol

Additionally, PACE 203H performs lead
surveillance with an intelligent lead-
breakage warning function, which oper-
ates independently in the atrial and
ventricular channels. PACE 203H enab-
les this function in a channel automati-
cally upon recognition that a lead is con-
nected. According to the definition of the
function, a lead is connected upon three
sensed or paced events.
In case an atrial or ventricular lead, or
any part of the circuit, fractures (acciden-
tally or on purpose, identified by three
failed deliveries of pacing stimuli), the
open lead symbol (see Figure 12)
appears in the respective section of the
upper display, accompanied with an
acoustic warning signal. The warning
signal is repeated as long as the
interruption persists. In addition, the
warning messages

Atrial lead disconnec-

ted

or

Ventricular lead disconnected

.

appear in the lower display (only if the
lower display is switched on). Once the
problem for the malfunction is resolved,
the warning message disappears auto-
matically, and the acoustic warning
signal ceases.
The user can confirm the error message

by pressing the key

Unlock/Lock

. Con-

firmation causes the warning message to
disappear and the acoustic signal to
cease, despite the fact, for example, that
the lead remains disconnected. In this
case, PACE 203H ceases the lead-
breakage warning message upon the
