System Description
The Merlin™ Pacing System Analyzer (PSA) Model EX3100 system provides you with the ability to
assess the electrical performance of a lead system during pulse generator implantation or invasive
lead-system troubleshooting. The Merlin PSA system uses the St. Jude Medical™ Merlin™ Patient Care
System (PCS).
In addition to the Merlin PCS, the Merlin PSA system consists of:
• a sterilizable patient cable
The Merlin PSA Patient Cable Model EX3150 connects the Merlin PSA with one to three implanted
leads.
• patient-cable adapters
The Merlin PSA Cable Adapter Model EX3170 and the Merlin PSA “M” Adapter Model EX3180
connect the Merlin PSA to commonly used PSA patient cables (see Connect the Leads to the
Merlin™ PSA). The PSA patient cables are then connected to the implanted leads.
For information on the Merlin PCS, refer to the Merlin PCS Model 3650 User’s Manual. For technical
data and other information on the Merlin PSA and accessories, refer to Technical Data.
Operator Profile
The intended operators of the Merlin™ PSA system include trained St. Jude Medical employees and
clinical personnel trained in pacing and electrophysiology, for example, nurses, technicians, or
physicians.
Note
Only persons properly trained to operate the Merlin PSA should do
so.
If the user connects both the Merlin PSA Model EX3100 and the PSA
Wand Model 3150 to the Merlin PCS, the programmer only enables
the Merlin PSA Model EX3100.
Refer to the Merlin PCS Model 3650 User’s Manual for Merlin PSA
installation instructions.

1-2 Introduction
Indications for Use
The Merlin™ Pacing System Analyzer (PSA) is indicated for use at the time of surgery in patients with
bradyarrhythmias, tachyarrhythmias, and/or heart failure undergoing implantation or lead revision of a
pacemaker, implantable cardioverter defibrillator, or cardiac resynchronization therapy system.
Intended Use
The Merlin™ PSA is intended to assess the pacing and sensing performance of the lead system prior to
pulse generator implantation, or during invasive lead system troubleshooting.
The Merlin PSA Patient Cable EX3150 is a three-channel resterilizable patient cable intended to
connect the Merlin PSA to as many as three IS-1, DF-1, or DF4 leads.
The Merlin PSA Patient Cable Adapter EX3170 is a three-channel adapter intended to connect the
Merlin PSA to as many as three disposable patient cables. The EX3170 Cable Adapter can connect to
the Model 4051L disposable patient cable for IS-1 leads or to the Model 4161 disposable patient cable
for DF4 leads. The opposite ends of the disposable patient cables connect to implantable pacing leads.
The Merlin PSA “M” Adapter Model EX3180 is intended to connect the Merlin PSA to the two-channel
Medtronic Model 2292 re-sterilizable patient cable. The opposite end of the Medtronic Model 2292
cable connects to implantable pacing leads.1
Following use, the patient cables must either be disposed or re-sterilized, depending on the
requirements of the cable.
Only use the Merlin PSA with the Merlin PCS.
Contraindications
There are no contraindications to the use of a lead-analysis device. The patient’s age and medical
condition, however, may dictate the pacing modes and lead assessment activities appropriate for the
patient.
The Merlin™ PSA is not intended for use as a temporary pacemaker or for life sustaining pacing
support.
The Merlin PSA is not intended for diagnostic purposes.
Warnings
Line-powered Equipment. An implanted lead or a lead with an extension cable constitutes a direct,
low-resistance current pathway to the myocardium. Due to the danger of tachyarrhythmias resulting
from alternating current leakage, extreme caution must be taken to only use line-powered equipment
according to its intended use as properly grounded line-powered Class I equipment used on or in the
vicinity of the patient.
Electrosurgical Cautery. Electrosurgical cautery could induce ventricular arrhythmias and/or
fibrillation, or may cause device malfunction or damage. If electrocautery is necessary, keep the current
path and groundplate as far away from the leads as possible.
1. The Medtronic Model 2292 re-sterilizable patient cable has an embedded resistor connected via connector pins P3
and P5 that enables Medtronic equipment to distinguish between different supported PSA cables. However, pins
P3 and P5 are not connected to the Merlin PSA which does not support this functionality.

Merlin™ PSA Help Manual 1-3
Burst Pacing. Use of atrial or ventricular burst pacing may result in ventricular tachycardia or
fibrillation. Defibrillation equipment should be readily available during the PSA session.
Handling Inserted Leads. Do not touch the terminal pins or exposed metal when handling inserted
leads. Do not allow the terminal pins or exposed metal to unintentionally contact electrically
conductive or wet surfaces.
Unconnected Atrial Leads. Do not operate the Merlin™ PSA in the DDD or VDD pacing mode with
only the ventricular pacing lead connected. Interference detected at the unconnected atrial input of
the Merlin PSA can result in false sensing and can drive the ventricular pacing rate to the Max Track
Rate setting.
Asystole. During threshold tests, asystole may result due to loss of capture.
Electromagnetic Interference (EMI). At high sensitivity (low numerical settings) and in the presence
of excessive levels of interference, the Merlin PSA may inhibit completely or revert to asynchronous
operation, pacing at the Base Rate. Additional sources of strong EMI that can temporarily affect the
operation of the Merlin PSA include the following:
• Electrosurgical equipment
• Diathermy equipment
• Some medical telemetry equipment, when operated within one meter of the Merlin PSA
• Communication transmitters such as cellular phones and “walkie talkies”.
Move the source of EMI as far from the Merlin PSA as possible.
Asynchronous Pacing. During asynchronous pacing operation, pacing stimuli may be inadvertently
delivered within the vulnerable period of the T-wave. This may be hazardous to patients with acute
myocardial infarction or who are otherwise predisposed to arrhythmias.
Precautions
Temporary Pacing. Do not use the Merlin™ PSA as a temporary pacemaker. It should not be used to
provide extended external pacing in situations where the patient is left unattended. Testing has not
been performed to support this function.
Power Loss. In the event of a power loss to the programmer, the Merlin PSA continues to pace in the
safe pacing mode for the length of backup battery life. Do not use the Merlin PSA as an external
temporary pacemaker. Connect the patient to an external temporary pacemaker as soon as possible.
For more information, see Safe Pacing.
High Output and Maximum Sensitivity. In the presence of large depolarization potentials or large
output pulses, use of high sensitivity settings (low numerical settings) may allow potentials to
inappropriately inhibit (or trigger) the output.
Connecting the Lead System. Install the Merlin PSA in the Merlin PCS storage compartment and
launch the PSA application. (For installation instructions, see the Merlin PCS Model 3650 User’s
Manual.) Then connect the sterile patient cables (and accessories, as necessary) to the Merlin PSA
before connecting the lead to the sterile patient cable.
Electrostatic Discharge (ESD). Pacing leads provide a low-impedance pathway to the heart.
Therefore, discharge any static electricity prior to touching the patient, the cables, or the leads.
Termination of Pacing. Abrupt termination of pacing stimuli may result in intervals of asystole before
an intrinsic rhythm is reestablished. Prior to terminating pacing, set the pacing mode to a demand
mode and then gradually reduce the pacing rate below the patient’s intrinsic rate. Once a spontaneous
rhythm is established, you can turn off pacing.

1-4 Introduction
Defibrillation/Cardioversion. The Merlin PSA may be damaged by defibrillation shocks when it is
connected to an implanted lead system. Test the Merlin PSA after it has been exposed to such charges
by launching the PSA application and verifying that the Merlin PSA is functional. Whenever possible,
for the safety of the patient, disconnect the Merlin PSA from the lead system before defibrillation or
cardioversion. After a typical defibrillation shock, the Merlin PSA will recover is less than five seconds.
Environmental Precautions. The Merlin PSA has been carefully designed and tested to ensure
reliability during normal use. However, electronic devices are susceptible to many environmental
stresses. Take precautions to avoid damaging the device, including (but not limited to) the following
examples:
• do not expose the Merlin PSA to extreme temperatures and/or humidity as that may result in
inaccurate measurements
• do not expose the Merlin PSA to mechanical shock as it may damage the Merlin PSA and result in
unreliable measurements
• do not store the Merlin PSA near magnets or magnetic-field-inducing coils as it may shorten its
lifetime.
Other environmental factors may affect proper performance of the device in the hospital setting. Use
of appropriate environmental health and safety practices helps prevent environmental damage to the
device.
Heart-Rate Monitoring. Monitor the patient’s heart rate with an ECG monitor while using the Merlin
PSA.
Liquid Immersion. Do not immerse the Merlin PSA in liquid or damage will result.
