MEDTRONIC MODEL 53401 BASIC OPERATION
Connector Setup 1. Verify that the temporary pacemaker is turned off. 2. Plug the patient cable (5433, 5846, 5487) or surgical cable (5832S, 5833S) into the socket on the connector block on top of the temporary pacemaker. 3. Verify that the cable clicks when it is inserted into the temporary pacemaker connector receptacle. The audible click verifies that the plug is completely inserted into the receptacle. 4. Pull gently on the cable after insertion to ensure a good connection. 5. Connect the lead to the cable. Match positive (+) and negative (-) leads to positive (+) and negative (-) sockets or clips for the atrium or ventricle.
Note: To disconnect the cable from the temporary pacemaker, do the following:
1. Press the connector release button on the patient cable plug. 2. Gently pull the plug from the receptacle.

MEDTRONIC MODEL 53401 BASIC OPERATION To Turn On § Press and hold the On/Off button momentarily to turn on the temporary pacemaker. The screen and the backlight illuminate, a self-test is initiated and the temporary pacemaker first searches for cardiac activity and then begins sensing and pacing (AAI/VVI mode). §
hen the temporary pacemaker is turned on, the W values are: RATE: 80 ppm (range 30-200 ppm) OUTPUT: 10 mA (range 0.1-25 mA) SENSITIVITY: 2 mV (range 0.1-20mV)
Note: If the batteries are nearing depletion, a red backlight begins flashing behind the battery status indicator. Warning: To prevent pacing into the vulnerable period of the T-wave, turn on the temporary pacemaker and turn down OUTPUT to the minimum amplitude. Determine sensing thresholds before turning up OUTPUT to the threshold values.
To Turn Off 1. U nlock the temporary pacemaker, if it is locked (see following section). 2. Press the On/Off button for two seconds. Note: If the On/Off button is not held for two seconds, the temporary pacemaker remains on and continues to pace at the currently selected values.
5
MEDTRONIC MODEL 53401 BASIC OPERATION Lock/Unlock The Lock/Unlock button locks the temporary pacemaker to prevent inadvertent adjustment of the parameters, or unlocks the temporary pacemaker when it is locked. When Locked: § The RATE, OUTPUT, and SENSITIVITY parameter values lock and cannot be adjusted. § Pacing therapy continues to be delivered at the currently selected values. § The Lock indicator appears in the lower right corner of the screen. § The On/Off button and RAP buttons lock and will not function. Notes: The temporary pacemaker locks when one of the following events occurs: § 60 seconds elapses after the last parameter adjustment is made. § When RAP is enabled, the temporary pacemaker will lock after 300 seconds/5 minutes have elapsed. § The Lock/Unlock button is pressed. If any parameter dials are adjusted or any buttons are pressed while the temporary pacemaker is locked, the Lock indicator flashes.

MEDTRONIC MODEL 53401 BASIC OPERATION Rate, Output, and Sensitivity Adjustments 1. If the Lock indicator appears in the lower right, press lock/unlock button. 2. To adjust RATE, OUTPUT, and SENSITIVITY, turn the RATE, OUTPUT, and SENSITIVITY dials clockwise to increase their values; turn the dials counterclockwise to decrease their values.

The screen displays a numerical value that reflects the current setting for each dial. Viewing Patient’s Intrinsic Rhythm Reduce the RATE gradually, while watching the ECG, until the patient’s intrinsic rhythm takes over and the temporary pacemaker is no longer pacing. Determining the Pacing Mode The pacing mode is determined by the chamber in which the lead is placed and by the SENSITIVITY setting. The temporary pacemaker can be set to several single chamber pacing modes (AOO, VOO, AAI, VVI). The sensitivity setting determines whether the pacemaker is in a synchronous (demand) or asynchronous mode. The pacing mode can be set by adjusting the SENSITIVITY. To increase SENSITIVITY, turn the dial counterclockwise (the mV value decreases). To decrease SENSITIVITY, turn the dial clockwise (the mV value increases). To turn off SENSITIVITY and allow the temporary pacemaker to pace asynchronously, turn the SENSITIVITY dial clockwise until the screen displays the term ASYNC. PACE

MEDTRONIC MODEL 53401 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 Thresholds 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 ppm under the patient’s intrinsic rate. 3. Adjust the output to prevent the risk of competitive pacing by setting OUTPUT to 0.1 mA. 4. Connect the temporary pacemaker to the patient lead system. 5. Decrease Sensitivity: Slowly turn the dial clockwise (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. 6. Increase SENSITIVITY: Slowly turn the dial SENSE counterclockwise (decrease mV value) mV until the SENSE 0.4 mV Async indicator starts flashing. § The PACE indicator stops flashing. § This value is the sensing threshold. 7. Set SENSITIVITY to half (or less) the threshold value. This setting provides at least a 2:1 safety margin. 8. Restore RATE and OUTPUT to previous values. PACE

MEDTRONIC MODEL 53401 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 Thresholds 1. Verify that the patient is connected to the temporary pacemaker and is being monitored on the ECG. 2. Set RATE at least 10 ppm above the patient’s intrinsic rate. This adjustment ensures pacing. The PACE indicator will be flashing. 3. Decrease OUTPUT: Slowly turn the OUTPUT dial counterclockwise until the ECG shows loss of capture. § The PACE and SENSE indicators flash intermittently. 4. Increase OUTPUT: Slowly turn the OUTPUT dial clockwise until ECG shows consistent capture. §T he 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 2:1 safety margin. 6. Restore RATE to previous value.

MEDTRONIC MODEL 53401 RAPID ATRIAL PACING (RAP) RAP can be used to interrupt some types of atrial tachycardias or to induce an atrial tachycardia. Caution: RAP is for atrial use only. Before enabling RAP, be sure that the atrial leads are connected to the atrium, not the ventricle. To access the RAP controls, flip open the small plastic RAP cover at the top of the temporary pacemaker and expose the controls.
Caution: Pacemaker-dependent patients will have limited or no intrinsic rate/rhythm.
To Deliver RAP: 1. Open the RAP cover to expose the RAP controls. 2. Press the ENABLE/DISABLE button once to enable RAP and enter RAP Standby. The RAP LED illuminates next to the RAP rate. The RAP rate displays in small text above the current pacing rate. Pacing continues at the currently displayed settings. 3. Adjust the RAP rate as needed. Turn the RATE dial clockwise to increase the RAP rate, or counterclockwise to decrease the RAP rate (range 80 ppm-800 ppm). 4. Press and hold the HOLD TO DELIVER button to deliver RAP burst. During RAP delivery: § The previously set pacing rate and the RAP rate will switch places between the small and large text fields during RAP delivery. § AOO pacing begins at displayed RAP rate and current atrial OUTPUT. The PACE LED flashes during delivery of RAP pulses. § RAP delivery stops when either the HOLD TO DELIVER button is released, or after 5 minutes have passed.

1. Continue to press and hold the HOLD TO DELIVER button. 2. Turn the RATE dial clockwise or counterclockwise to adjust RAP rate. 3. Turn the OUTPUT dial clockwise or counterclockwise to adjust atrial output.
Resuming Pacing at Previous Settings 1. Release the HOLD TO DELIVER button. The temporary pacemaker stops delivering RAP and resumes operation at the non-RAP settings within 3 s. 2. Press the ENABLE/DISABLE button once to exit RAP Standby and disable RAP controls. The RAP LED will no longer be illuminated when the device has exited RAP Standby mode, and the RAP rate will no longer be displayed above the pacing rate. If the OUTPUT is adjusted during RAP, the new setting is retained when RAP is terminated. CAUTION: If the temporary pacemaker continues to deliver RAP after the HOLD TO DELIVER button is released, press and hold the On/ Off button to stop RAP. If RAP continues to be delivered, remove the batteries from the temporary pacemaker and return the temporary pacemaker for service.
