About the EP Studies Function
Intended Use and General Warning
Intended Use and General Warning
EP (Electrophysiologic) Studies is a special function of the
Medtronic® 9790 series programmer that allows you to use the
patient’s implanted pacemaker to noninvasively deliver high-rate
cardiac stimulation. Programmable mode, interval, and delay
parameters allow you to set up protocols for delivering either
programmed electrical stimulation (PES) or burst stimulation.
Intended Use
The EP Studies function is intended for use in measuring or
assessing conduction properties of the heart and inducing or
terminating tachyarrhythmias. The EP Studies function covered
in this supplement applies only to the pacemakers listed below.

General Warning
The EP Studies function is intended for use only by those trained
in electrophysiologic studies. The stimulation options of this
function should be applied only under conditions of careful
patient monitoring and control. High-rate stimulation of the
ventricles can result in ventricular fibrillation. An external
defibrillator should be placed on standby and be kept
immediately available during the use of the EP Studies function.
About the EP Studies Function
Precautions and Considerations
The following precautions and important considerations apply to
using the EP Studies function.
Loss of Clinician-Selected Data Collection
Starting EP Studies disables the clinician-selected diagnostic data
collection option (if programmed) and clears the collected data
from the pacemaker memory.
Once interrogated, the collected data is available on the
programmer throughout the patient session, but is lost when you
end the session. You should view and print the collected data
before ending the session.
This data collection remains disabled until the clinician-selected
diagnostic is reprogrammed (see “Ending the Patient Session” on
page 1-5).
Precautions and Considerations
Using EP Studies does not affect automatic (non-selectable)
diagnostic data collection functions.
Using VOO Backup Ventricular Pacing
The VOO Backup option delivers asynchronous pacing to the
ventricles during atrial stimulation. These pacing stimuli may
compete with intrinsic ventricular activity. Refer to page 1-10 for
information about using the VOO Backup pacing option.
Pacemaker Battery Condition
At reduced pacemaker battery capacity, execution of a PES or
burst protocol can result in a significant temporary decrease in
pacemaker battery voltage. See “Effects of Tripping the ERI” on
page 1-4.
EP Studies Supplement1-3

About the EP Studies Function
Precautions and Considerations
Selecting an Appropriate Amplitude Setting
Selecting an amplitude setting of 7.5 volts for high-rate
stimulation is not recommended. While this setting can provide
the maximum available output, its use can result in a significant
temporary decline in output voltage. An output setting of 5.0 volts
or less, as indicated by the pacemaker battery test, will reduce
battery drain and can provide a more constant output during
protocol delivery.
The EP Studies Pacemaker Battery Test
Results of the EP Studies Pacemaker Battery Test, which are
automatically available when you first start an EP Studies session,
should be used as a guide for selecting pulse width and amplitude
settings for the protocol stimuli. You can access the pacemaker
battery test results as needed by selecting the
Effects of Tripping the ERI
If the pacemaker ERI (Elective Replacement Indicator) trips
during a PES or burst protocol, stimulation stops and the
pacemaker reverts to the ERI pacing mode and rate settings.
Unless the ERI condition is temporary and can be reset
immediately, this situation can leave the patient in a potentially
dangerous condition with the EP Studies function unavailable.

button.

Positioning the Programming Head
During delivery of a PES protocol or burst stimulation, the
programming head must be held steady in its proper position
over the patient’s pacemaker. Movement of the programming
head can result in abrupt termination of the stimulation sequence.
Lifting the programming head at any time during the use of an EP
Studies function causes the pacemaker to return to its
permanently programmed state.
Communication

Missing Marker
About the EP Studies Function
Precautions and Considerations
Interruption of Marker Telemetry
The communication between the programmer and pacemaker
momentarily interrupts the transmission of marker telemetry.
This interruption can result in missing markers on the trace
display and the chart recording.
Symbols appearing on the recording above the ECG trace indicate
the point at which communication occurred.
▼ = Programming or interrogation command to the pacemaker.
▲ = Telemetry response from the pacemaker.

Ending the Patient Session
Reprogramming the Pacing Mode – If you programmed the
pacemaker from a rate responsive mode as required to access the
EP Studies function, reprogram the pacemaker to the desired
mode and parameter settings prior to ending the session.
Reprogramming Diagnostic Data Collection – As previously
stated, using EP Studies disables the clinician-selected diagnostic
data collection function, if programmed on (see “Loss of
Clinician-Selected Data Collection” on page 1-3). This data
collection function will remain disabled unless you reprogram the
desired data collection options. Reprogram these options after you
finish using EP Studies, but before you end the patient session.

EP Studies Access
The EP Studies function is available for the applicable pacemakers
(Table 1-1) only if 9952A software has been installed on your
programmer.
To verify whether or not this software has been installed, select
the Tests icon in the tool palette (during a session). If the software
has been installed, “EP Studies” appears on the Tests menu.

About the EP Studies Function
The PES Protocol
A drive train of up to 30 stimuli (S1).
Up to three premature stimuli (S2, S3, and S4).
An optional delay period with or without pacing stimuli.
A “Scan” option that causes the PES sequence (and delay
period) to automatically repeat. You can set the interval of the
last premature stimulus to decrease with each repetition.
Optional asynchronous backup ventricular pacing during
atrial stimulation (dual chamber models).

Start of the PES sequence is
synchronized to a paced or
sensed event.
