Procedure of Recording ECG
- 1. BY- AHMED SODHA M.Sc.(N)- M.S.N.
- 2. q INTRODUCTION:- • AN ECG IS A RECORDING OF WAVEFORMS THAT REFLECTS THE ELECTRICAL ACTIVITY OF THE HEART. • AN ELECTROCARDIOGRAM IS A GRAPHIC RECORD OF THE ELECTRICAL IMPULSES THAT ARE GENERATED BY DEPOLARIZATION & REPOLARIZATION OF THE MYOCARDIUM.MYOCARDIUM. • ECG – A GALVANOMETER & ELECTRODES WITH SIX LIMB LEADS AND SIX CHEST LEADS. RECORDED ON GRAPH PAPER WITH DIVISIONS.
- 3. q ELECTROCARDIOGRAPHIC PAPER:- • A GRAPH PAPER WITH EACH SMALL SQUARE MEASURING 1mm X 1mm. • ECG RECORDERS & MONITORS ARE STANDARDIZED AT A SPEED OF 25 mm / sec. TIME IS MEASURED ON HORIZONTAL AXIS & VOLTAGE ON Y AXIS. • EACH SMALL SQUARE REPRESENTS 0.04 SECONDS. • FIVE SMALL SQUARES MAKE UP ONE LARGE SQUARE REPRESENTING 0.20 SECONDS.REPRESENTING 0.20 SECONDS.
- 5. q PURPOSE:- • TO ASSESS THE CARDIAC FUNCTION (RATE , RHYTHM AND CONDUCTION). • TO DIAGNOSE CARDIAC RHYTHM DISORDERS (Eg. HEART BLOCK, DYSRHYTHMIAS) • TO DIAGNOSE CARDIAC DISEASES (Eg. MI) • TO DETECT THE EFFECTS OF ELECTROLYTE IMBALANCE ON CARDIAC FUNCTION (Eg. HYPERKALEMIA, HYPOKALEMIA, ETC) • TO EVALUATE EFFECTS OF TREATMENT (Eg. ADMINISTRATION OF CARDIAC DRUGS).
- 6. q ARTICLES:- • ECG MACHINE WITH 12 LEADS • ELECTROCONDUCTIVE GEL • TISSUE PAPER / TOWEL • KIDNEY TRAY / PAPER BAG q PLACEMENT OF ELECTRODES Ø 4 ARE LIMB ELECTRODES: RIGHT ARM : RED• RIGHT ARM : RED • LEFT ARM : YELLOW • LEFT LEG : GREEN • RIGHT LEG : BLACK
- 7. q PLACEMENT OF ELECTRODES (CONT.):- • V1 - ELECTRODE POSITIONED IN THE 4th INTERCOSTAL SPACE IN THE RIGHT STERNAL BORDER. • V2 - 4th ICS IN THE LEFT STERNAL BORDER. • V3 - MIDWAY BETWEEN V2&V4. • V4 - 5th ICS IN THE LEFT MIDCLAVICULAR LINE. • V5 - SAME LEVEL AS V4, ANTERIOR AXILLARY LINE. • V6 - SAME LEVEL AS V4 & V5, MIDAXILLARY LINE.• V6 - SAME LEVEL AS V4 & V5, MIDAXILLARY LINE.
- 8. q PROCEDURE:- • EXPLAIN THE PURPOSE & PROCEDURE OF ECG TO PATIENT. •ENSURE THAT THE PROPER STANDARD ECG MACHINE WITH WORKING CONDITION. • PROVIDE SUPINE POSITION TO PATIENT. • PERFORM HAND WASHING. • ARRANGE ECG MACHINE, GEL & ECG PAPER IN TROLLY.TROLLY. • EXPOSE CHEST COMPLETELY. ASSIST PATIENT TO PUT ON A FRONT OPEN LOOSE GOWN OR SHIRT. (ASK FEMALE PATIENT TO REMOVE ALL TIGHT FITTING CLOTHING AROUND THE CHEST. • APPLY ECG GEL ON LEAD PLACEMENT SITES AND POSITION ALL ELECTRODES APPROPRIATELY. (ENSURE PRIVACY DURING PROCEDURE)
- 9. q PROCEDURE (CONT.):- • START TO RECORD ECG. • AFTER RECORDING REMOVE ALL ECG LEADS PROPERLY . • CLEAN ECG GEL FROM PATIENT’S BODY WITH TISSUE PAPER OR TOWEL. • REPLACE THE ARTICLES PROPERLY. • RECORD THE PROCEDURE IN NURSES RECORD BOOK. • SEND ECG REPORT TO PHYSICIAN.• SEND ECG REPORT TO PHYSICIAN. ♦ VIDEO LINKS ♦ https://www.youtube.com/watch?v=UcPqVjjCaik https://www.youtube.com/watch?v=kwLbSx9BNbU https://www.youtube.com/watch?v=RYZ4daFwMa8
