OBJECTIVES The objective of this protocol is to provide guidance for the nursing staff care for a patient requiring temporary transcutaneous pacing. II. INDICATIONS FOR USE Initiate this protocol for patients requiring a temporary transcutaneous pacing for symptomatic bradycardia, or bradycardia due to autonomic instability, drug toxicity and/or anesthesia, temporary bridge in presence of permanent or temporary pacemaker failure, Type II second degree or third degree AV block. Prepare for temporary transvenous or emergent permanent pacemaker. III. DEFINITIONS Asynchronous Pacing Mode The pacemaker releases a pacing stimulus at the programmed rate regardless of the heart’s intrinsic activity. Demand Pacing Mode The pacemaker withholds its pacing stimulus after sensing a spontaneous depolarization. Also thought of as the pacer inhibiting when it senses intrinsic activity or that is synchronizes with intrinsic activity of the heart. Mode Can be either demand or asynchronous. Output Level of energy, expressed in milliamperes (mA). Rate The rate at which pacing stimuli is emitted from pulse generator. Sensitivity The degree to which a pacemaker is responsive to levels of electrical activity in the heart. Stimulation Threshold The least amount of electrical energy (measured in mA) required to elicit a ventricular contraction. IV. RESPONSIBILITY A. Authorized Prescriber 1. Write an order to initiate and maintain transcutaneous pacemaker including the following: a. Output (mA) Version 5.0 The Johns Hopkins Hospital Policy Number CC642 Nursing Practice and Organization Manual Vol II: Clinical Critical Care Effective Date 12/04/2013 Approval Date N/A Subject Pacemaker, Transcutaneous, Management of the Patient with B. Page Supercedes 2 of 4 07/01/2010 b. Rate 2. Order continuous cardiac monitoring. 3. Order analgesics or sedation as needed Registered Nurses (RN) 1. Who have demonstrated competency will attach and maintain external pacemaker to patient. V. PROCEDURE A. B. Assessment: 1. Assess the patient’s intrinsic cardiac rhythm (if not continuously pacing) and hemodynamic response to determine need for external pacing. 2. Assess for other factors that may cause or exacerbate bradycardia including current medications (e.g. digoxin, calcium channel blockers, beta blockers, amiodarone) and lab values. 3. Within one hour of assuming care of the patient who has intermittent or continuous pacing, every 2 hours and prn. a. SETTINGS: verify the pacemaker settings per the authorized prescriber order: i. Rate ii. Pacer output (mA) b. Assess for pacing effectiveness via continuous cardiac monitoring: note failure to sense, failure to pace or failure to capture. c. Assess hemodynamic response to pacing including: i. Vital signs (It is recommended that cuff BP should be obtained in the right arm due to elevation of pressures in the left arm with external pacing). ii. Level of consciousness iii. Urine output d. Check electrode sites for adherence and skin integrity. If adherence is a problem, clip hairs. DO NOT SHAVE, as it increases the risk of burns. e. Assess for evidence of pain and need for analgesics or sedation. f. Assure alarms on external pacer are set appropriately and remain on at all times. 4. Assess every 4 hours and prn the following a. Underlying rhythm if visible. In order to view underlying rhythm when continuously pacing, utilize the 4:1 button, (not all makes/models of transcutaneous pacers have this function). By pushing and holding the 4:1 button, pacing stimuli is temporarily withheld so that every 4th beat is a paced beat. Pacer setting remain unchanged. b. Percent of time paced (complete, intermittent, non-pacing). c. Pacemaker settings as compared to orders (output (mA), rate). d. Carotid, femoral or peripheral pulses. 5. Asynchronous pacing should only be performed in emergency situations when there are no other alternatives. (Zoll M and Zoll R Series biphasic AEDs/Defibrillator default to demand pacing/ asynchronous pacing can be initiated by pressing the “Asynch Pacing On/Off key”. Interventions 1. For the Zoll M Series biphasic AED/Defibrillator, attach the Zoll 3-lead ECG monitoring lead wires to patient. The Zoll M Series will not pace without lead wires applied to patient. 2. For the Zoll R Series biphasix AED/Defibrillator the 3 lead ECG monitoring lead system is built into the OneStep CPR Complete pads. a. Pediatrics patients: must attach the Zoll 3-lead ECG monitoring lead wires to the patient. 3. Placement of pacing electrode pads: a. Check the expiration date on the pacing electrode pad package. Discard if they are expired or the package has been opened. b. Remove any medication patches from the chest (particularly nitroglycerin patches and paste).

C. Supercedes 3 of 4 07/01/2010 Prepare the patient’s skin by washing with soap and water, rinse and dry well. Clip excess hair-DO NOT SHAVE. Using a towel, use a circular motion to abrade the application site. DO NOT use alcohol or benzoin on the skin as these may increase the risk of burns. d. Avoid placement of pads over bony structures, external wires and open skin areas. e. If the pacing electrodes have been previously placed frontally for defibrillation or cardioversion, they may be left in place for the first attempt to pace. If immediately unsuccessful, use the following positioning that is preferred for pacing. i. Apply the “front/apex/lateral” pacing pad at the left, fourth intercostal space, midclavicular line. Adjust position of pad below and lateral to breast tissue to ensure optimal adherence. Roll the electrode onto the patient's chest. Evacuate any air pockets that are trapped between the skin and the electrode. Press down on the entire surface to assure uniform adhesion. Avoid touching the stimulation side of the electrode pad. ii. Using the same application method described above, apply the back pad between spine and left scapula at the level of the heart with the monitoring portion pointing down. The posterior pad should be directly behind the anterior pad in a “sandwiched” position. iii. In emergency situations such as VT or Vfib switch from pacer mode to defibrillator mode. Defibrillation can be done with the pacing pads in the front and back position. 4. Consider sedation (IV analgesics or sedation) for pacing discomfort. 5. Take the following steps to provide fixed-rate (asynchronous) or demand pacing: a. Follow manufacturer’s operating instructions for turning on the defibrillator, monitor and pacing unit. b. Select Lead II and maximize R-wave size. The Zoll R Series will have a P before the Lead selected to indicate that the 3 lead ECG monitoring is from the OneStep CPR Complete pads. c. Confirm the suspected arrhythmia on the ECG. d. Select demand or asynchronous mode, rate and output (mA) per physician order. (Slowly in increase the energy level (mA) until consistent capture occurs at the prescribed rate). e. Assess electrical capture by observing the ECG display. Capture is usually evidenced by a pacer spike followed by a wide QRS complex and tall, broad T waves. f. Assess mechanical or ventricular capture by evaluating cardiac output. Each QRS should be accompanied by a palpable pulse. Use right carotid, femoral or brachial pulse to avoid confusion between the jerking muscle contractions caused by the pacer and true pulse. g. As soon as there is capture, adjust the current ouput to 10% above the lowest effective level (stimulation threshold). h. Change electrode every 24 hours and prn. i. Obtain 12 lead ECG every day and prn. j. Keep external pacemaker/defibrillator plugged in at all times except during transport (battery limit is about 2 hours). k. If the Zoll is used as the primary monitor, set alarm limits on the external pacemaker/defibrillator based on the patient’s condition.
