INTERDISCIPLINARY CLINICAL MANUAL Policy & Procedure NUMBER: CC 10-013 Section: Cardiac Monitoring: Cardiac Rhythm Assessment and Telemetry Monitoring Cardiovascular Date Issued: May 2006 Source: Distribution: Heart Health Resource Team All Date To Be Reviewed: Issuing Authority: May 2009 Karen MacRury-Sweet Health Services Director TITLE: THIS INCORPORATES POST-ENTRY LEVEL SKILLS FOR RNS AND LPNS, WHICH REQUIRE COMPETENCY ASSESSMENTS PRIOR TO PERFORMING POLICY 1. Skin preparation and lead application for cardiac monitoring is a: 1.1. post-entry level competency for LPNs that requires certification before performing. 1.2. basic nursing procedure for RNs. 2. Cardiac rhythm assessment is a post-entry level competency for RNs (applicable in specific units/areas) that requires certification before performing. 3. As the use of cellular phones and two-way radios can interfere with medical equipment, signage restricting use is to be posted in patient care areas where cardiac monitoring or telemetry occurs. GUIDING PRINCIPLES Cardiac Monitoring: CC 10-013 Cardiac Rhythm Assessment and Telemetry Monitoring Learning Module 1 1. Cardiac Monitoring provides a means to: 1.1. monitor a patient's cardiac electrical activity. 1.2. document cardiac electrical activity for diagnostic reasons or documentation. 1.3. identify ECG changes indicating ischemia. 1.4. identify arrhythmias. 1.5. determine effect of drugs and/or electrolytes on the heart’s electrical system. 2. Adequate skin contact and accurate lead placement are necessary to ensure quality tracings. Consider: 2.1. Anatomical landmarks for accurate lead placement 2.2. Shaving hair from appropriate areas 2.3. Gently rubbing skin surfaces with alcohol swab, dry gauze, or soap and water to remove oily residue and dead skin cells. 2.4. Allowing skin to dry thoroughly before applying electrodes. 2.5. Changing electrodes every 48 hours to avoid skin irritation and to ensure electrode gel is sufficient for conduction. 3. Troubleshoot as necessary to ensure the ECG pattern is clear and distinct. Monitor or lead adjustments may be required to improve quality of recording. 4. Lead II is most commonly used because it produces a clear QRS complex (which reflects ventricular activity) and a positive P wave (which shows atrial activity.) 5. Multi-lead ECG monitoring (5 & 6 Lead) can help eliminate nuisance alarms, give a clearer recording and improve arrhythmia analysis. 6. Avoid placing electrodes over pacemaker site or automatic implantable cardioverter defibrillator (AICD) to prevent possible electrical interference and inappropriate alarms. Refer to equipment specific manual for electrode placement recommendations. 7. When using 6 leads, the V5 lead is recommended for ST depression monitoring. 8. The V1 lead is recommended for arrhythmia detection. EQUIPMENT • • • • • • • • 3, 5 or 6 electrodes monitor or telemetry unit & batteries if applicable cable (s) / leadwire (s) alcohol prep disposable razor or shave clippers soap and water washcloth tape PROCEDURE Cardiac Monitoring: CC 10-013 Cardiac Rhythm Assessment and Telemetry Monitoring Learning Module 2 RNs and LPNs 1. Explain procedure to patient and family. 2. Shave hair from chosen sites. 3. Gently rub skin surface to remove dead skin cells at selected sites. 4. Wash site with soap and water or alcohol to remove oily residue or dead skin cells. 5. Allow skin to dry thoroughly. 6. Apply electrodes as recommended. Connect the lead wires to the electrodes that snap on before placement on patient. Refer to diagrams – Appendixes A, B, and C. 7. To prevent rotation of the leadwire, tugging & artifact, make a stress loop on each leadwire and tape the stress loop to the patient. Do not tape across the electrode. 8. Connect the cable to monitor or telemetry unit. 9. Instruct the telemetry patient re activating the graph button and pressing the nurse call bell. Reinforce transmission range; i.e. Not able to leave unit. RNs only 10. Select monitoring features from ECG menu, i.e. lead(s) displayed, ECG size, pacemaker detection, alarm limits, QRS volume, and arrhythmia and where applicable, ST monitoring & lead analysis. 11. Observe cardiac rhythm on monitor. 12. For trouble-shooting, refer to attached trouble shooting guide and/or manufacturer’s instructions / operation manual. 13. Systematically assess cardiac rhythm. 14. Assess for life threatening arrhythmias. 15. Document assessment of cardiac rhythm strip at the beginning of each shift, with rhythm changes and/or with changes in patient’s clinical condition. Refer to unit-specific policy and procedure, guideline or protocol, if applicable. Include the following in the documentation: 15.1. heart rate, 15.2. rhythm, 15.3. PR, 15.4. QRS, 15.5. QT, 15.6. ST 15.7. rhythm assessment. Cardiac Monitoring: CC 10-013 Cardiac Rhythm Assessment and Telemetry Monitoring Learning Module 3 15.8. interventions.
