Sensing Thresholds
Note: The sensing threshold is the least sensitive setting at which the pacemaker can detect a heartbeat. To find the atrial and ventricular thresholds, monitor the patient’s ECG as you follow the procedure below.
Caution: Pacemaker-dependent patients will have limited or no intrinsic rate/rhythm.
To Find Atrial or Ventricular Sensing Threshold
1. Turn on the temporary pacemaker without connecting it to the patient lead system.
Caution: Do not connect the temporary pacemaker to the patient lead system until step 4.
2. Set Rate to at least 10 min–1 (ppm) under the patient’s intrinsic rate. This adjustment ensures non-pacing.
3. Adjust the atrial or ventricular output to prevent the risk of competitive pacing.
Atrial: Set A Output to 0.1 mA.
Ventricular: Set V Output to 0.1 mA.
4. Connect the temporary pacemaker to the patient lead system.
5. Navigate to the mode selection menu and select the appropriate pacing mode for the patient leads that are connected to the patient.
• Select DDD mode if both channels are connected
• Select AAI mode if only the atrial channel is connected
• Select VVI mode if only the ventricular channel is
connected
6. Navigate to the Sensitivity settings.
a. Complete steps 7 thru 9 for the A Sensitivity setting,
if the atrial channel is connected.
b. Complete steps 7 thru 9 for the V Sensitivity setting,
if the ventricular channel is connected.

Sensing Thresholds
7. Decrease Sensitivity: Slowly turn the menu parameter dial counterclockwise (increase mV value) until the sense indicator stops flashing.
The pace indicator flashes continuously, but capture is not likely because the output value is set to minimum.
8. Increase Sensitivity: Slowly turn the menu parameter dial clockwise (decrease mV value) until the sense indicator starts flashing.
• The pace indicator stops flashing
• This value is the sensing threshold
9. Set Sensitivity to half (or less) the threshold value. This setting provides at least a 2:1 safety margin.
10. Restore Rate, A Output, or V Output to previous
values.

Stimulation Thresholds
Note: The stimulation threshold is the minimum output pulse needed to consistently capture the heart. To find this threshold, monitor the ECG as you follow the procedure below. To reduce the risk of competitive
pacing, find the sensing threshold first (if the patient’s intrinsic rate is adequate).
To Find Atrial or Ventricular Stimulation Threshold
1. Verify that the patient is connected to the temporary pacemaker and is being monitored on the ECG.
2. Set Rate at least 10 min–1 (ppm) above the patient’s intrinsic rate.
This adjustment ensures pacing. The pace indicator flashes.
3. Decrease Output: Slowly turn the output dial counterclockwise until ECG shows loss of capture.
• Pace and sense indicators flash intermittently.
4. Increase Output: Slowly turn the output dial clockwise until ECG shows consistent capture.
• The pace indicator flashes continuously; the sense
indicator stops flashing
• This value is the stimulation threshold
5. Set Output to a value at least 2 to 3 times greater than the stimulation threshold value. This setting provides at least a 2:1 safety margin.
6. Restore Rate to the previous value.

RAP (Rapid Atrial Pacing)
RAP can be used to interrupt some types of atrial tachycardias or to induce an atrial tachycardia.
Caution: RAP is for atrial use only. Be sure that the atrial leads are connected to the atrium, not the ventricle, before enabling RAP.
Caution: RAP may result in tachycardia, acceleration of existing tachycardia, or fibrillation. Apply high rates under careful patient monitoring and control. Monitor the patient’s ECG and blood pressure, and ensure that defibrillation equipment is immediately available.
To Deliver RAP:
1. Navigate to the Pacing Parameters menu.
2. Press the up or down arrow key to highlight Rapid Atrial Pacing (RAP).
3. Verify that the leads are in contact with the atrium and are connected to the atrial channel of the temporary pacemaker through a patient or surgical cable.
4. Press the enter key to open the RAP screen. The RAP screen displays the RAP rate [initially the rate of 250 min–1 (ppm)]. Pacing continues at currently displayed settings.
5. Adjust RAP rate as needed. Turn the menu parameter dial clockwise to increase rate, or counterclockwise to decrease rate.
Note: The range for RAP is 80 min–1 (ppm) to 800 min–1 (ppm).
6. Press and hold the enter key to deliver RAP burst. AOO pacing begins at displayed RAP rate and current A Output. The A Pace LED flashes during delivery of RAP pulses.
Note: RAP delivery stops when either the enter key is released, or after 1 min
has passed.
To exit the RAP screen, use the up or down arrow key to select
back, and then press the enter key.

Battery Replacement
Battery Installation and Replacement
Note: Medtronic recommends disconnecting device from patient before replacing battery.
1. Press the battery drawer latch release button until the battery drawer opens.
2. Remove the old batteries.
3. Install two new LR6-sized (AA-sized) alkaline batteries. Verify that the batteries align with the polarity markings on the inside of the battery drawer.
4. Close the battery drawer firmly until the battery drawer is fully latched.
Note: Failure to close the battery drawer completely can result in the battery drawer opening and the temporary pacemaker shutting down.
5. Discard the old batteries properly according to local regulations.
Notes
Replace the temporary pacemaker batteries in the following situations:
– Replace the batteries for each new patient – Replace the batteries when the low battery indicator appears during
temporary pacemaker operation
– Replace the batteries at least once every week when the temporary
pacemaker is in continuous use
Install the batteries with proper polarity. The temporary pacemaker does
not turn on or provide pacing therapy with incorrect battery polarity
If during an emergency situation the batteries must be replaced
while the temporary pacemaker is in use, ensure that the temporary pacemaker is locked before replacing the batteries. Pacing is maintained at the current settings for 30 s, minimum, if the settings are at nominal values.

Brief Statement Model 5392 Dual Chamber Temporary Pacemaker
Product useful life
The expected service life of the temporary pacemaker is five years. Medtronic will not service or repair the temporary pacemaker after five years. Contact your Medtronic representative to replace your temporary pacemaker after it has been in service for five years. Intended Use: The Medtronic Model 5392 dual chamber temporary pacemaker is intended to be used in conjunction with a cardiac pacing lead system for temporary single or dual chamber pacing in a clinical environment by trained personnel. The temporary pacemaker can be used where short-term demand (synchronous) or asynchronous pacing is indicated for therapeutic, prophylactic, or diagnostic purposes. The temporary pacemaker must be used in an environment where the patient is monitored continuously to ensure that it is operating properly and delivering appropriate therapy to the patient. Contraindications: There are no known contraindications to the use of temporary pacing as a means to control the heart rate. The patient’s age and medical condition, however, may dictate the type of temporary pacemaker and lead system used by the physician. Pacing modes which allow sensing in the atrium to trigger a ventricular response are contraindicated in the presence of rapid atrial arrhythmias such as atrial fibrillation or atrial flutter. Atrial pacing is ineffective in the presence of atrial fibrillation or flutter. Single chamber atrial pacing is contraindicated in the presence of AV conduction disorders. Asynchronous pacing is contraindicated in the presence of intrinsic cardiac rhythms. Atrial high-rate burst pacing therapy is intended for use in the atrium only. High-rate burst pacing in the ventricle may result in life-threatening arrhythmias. The temporary pacemaker is MR Unsafe. Warnings/Precautions: Monitor the patient continuously while the temporary pacemaker is in use to ensure it is operating properly and delivering appropriate therapy to the patient. ECG monitoring should be in use and defibrillating equipment should be placed on standby and be kept immediately available during pacing lead insertion, pulse generator connection and adjustment, measurements of stimulation thresholds or sensed potentials, and application of antitachycardia burst therapy. Use of high rates in the atrium may result in accidental conduction to the ventricle. Defibrillation equipment should be kept immediately available during high-rate pacing. Operational failure of the temporary pacemaker can occur as the result of battery depletion, mishandling, or random component failure. Complications related to the use of temporary external pacemakers such as the Model 5392 include, but are not limited to, asystole following abrupt cessation of pacing, inhibition, and reversion. Potential complications related to the use of pacing lead systems with the Model 5392 include, but are not limited to, myocardial irritability resulting in fibrillation, infarction, pericarditis, rejection, muscle and never stimulation, and infection. Complication related to inhibition or reversion of the pacemaker in the presence of strong electromagnetic interference. Whenever possible, for the safety of the patient, disconnect the temporary pacemaker from the implanted lead system before defibrillating or cardioverting. Excessive defibrillation energy can damage the temporary pacemaker. This can result in a large current flowing through the implanted lead system and temporary pacemaker, which could reduce intended defibrillation energy delivered to the patient or cause myocardial damage. A lead with extension cable constitutes a direct, low-resistance current path to the myocardium. During connection and testing procedures, only battery-powered instrumentation should be used. Extreme caution must be taken to properly ground all line-powered equipment used in the vicinity of the patient. Electrosurgical units can cause tachyarrhythmias by inducing current on the leads. Improper connection, displacement or fracture of leads or cables may result in pacemaker system failure. Inspect leads and cables for damage before each use. The pacing lead system may cease to function at any time due to improper connections or lead-related problems such as displacement or fracture. Do not modify the temporary pacemaker. Modifications could impact the temporary pacemaker effectiveness and adversely affect patient safety.
See the device manual for detailed information regarding the procedure, indications, contraindications, warnings, precautions, and potential complications/adverse events. For further information, please call Medtronic at 1 (800) 328-2518 and/or consult Medtronic’s website at
