EKG TECHNICIAN STUDY GUIDE FOR EKG, ECG TESTING

TermDefinition
ELECTROCARDIOGRAM THE GRAPHIC RECORD OR TRACING OF THE HEARTS ELECTRICAL ACTIVITY PRINTED OR DRAWN
ELECTROCARDIOGRAPH MACHINE WITH CODED OR NUMBERED LEADS THAT ATTACH TO ELECTRODES PLACED ON THE PATIENT'S CHEST, ARMS AND LEGS.
NUMBER OF ELECTRODES ON A STANDARD 12 LEAD EKG 10
PLACEMENT OF ELECTRODES FOR 12 LEAD EKG TEST RIGHT ARM, LEFT ARM, RIGHT LEG, LEFT LEG, V1 AT 4TH INTERCOSTAL RIGHT SIDE OF STERNAL BORDER, V2 4TH INTERCOSTAL LEFT SIDE OF STERNAL BORDER, V3 BETWEEN V2 & V4, V4 MIDCLAVICULAR 5TH INTERCOSTAL , V5 HORIZONTALLY WITH V4 , V6 IS MIDAXILLARY LEFT
COLOR CODES FOR LEADS LA- BLACK, RA- WHITE, V1-RED, V2- YELLOW, V3- GREEN, V4- BROWN , V5 BLUE, V6- PURPLE, LL- BLACK, RL- WHITE
ECG RYTHYMS MAY BE SHOWN ON AN LED DISPLAY OR AN OSCILLOSCOPE OR PRINTED ON GRAPH PAPER WITH STATIC TRACING
THE GRAPH PAPER HORIZONTAL AND VERTICAL LINES THAT FORM GRIDS A TRACING MADE BY CALIPERS IS RECORDED ONTO BY MACHINE.
HORIZONTAL AXIS (LINES ) USED TO CALCULATE DISTANCE AND RATE OF THE WAVEFORMS
VERTICAL LINES USED TO CLACULATE AMPLITUDE OF THE WAVEFORMS
LARGE SQUARES EQUAL 5 SMALL SQUARES, READ .20 Secs HORIZONTALLY OR .5mV VERTICALLY
SMALL SQUARES EQUAL 1/5 OF LARGE SQUARES, EACH REPRESENTS .04 SECS IN DURATION HORIZONTALLY AND .1mV VERTICALLY
DYSRYTHMIA ANY ABNORMAL RYTHYM
ARTIFACT CAUSED BY ELECTRICAL OR MAGNETIC INTERFERENCE OR PATIENT MOVING, SWEATING, SEIZURES, LOOSE ELECTRODE DURING THE EKG TEST
LEADS EACH PROVIDES A VIEW OF THE HEARTS ELECTRICAL OUTPUT DURING TESTING
UPWARD DEFLECTION IMPULSES THAT TRAVEL TOWARDS A POSITIVE ELECTRODE ARE RECORDED /\
DOWNWARD DEFLECTION IMPULSES THAT TRAVEL TOWARDS A NEGATIVE ELECTRODE ARE RECORDED `\/
EKG STEPS OF INTERPRETATION 1.RYTHYM 2.RATE 3. P-WAVE 4. PR-INTERVAL 5. QRS- INTERVAL, 6. T-WAVE 7. Q-T INTERVAL 8. ST SEGMENT
RYTHYM MEASURE DISTANCE FORM ONE R TO THE NEXT R, ARE THEY REGULAR, OR IRREGULAR, OR IRREGULARLY IRREGULAR
RATE HEART RATE COUNT IS MEASURED BY QRS COMPLEXES OVER 6 SECOND X 10 P & R rates use # boxes X 10
P- WAVE FIRST UPWARD DEFLECTION ON THE RECORDING PRECEDES THE QRS , REPRESENTS ATRIAL DEPOLARIZATION AMPLITUDE IS 0.05-0.25, NORMAL DURATION IS 0.06-0.11 SECONDS
P-R INTERVAL INDICATES AV CONDUCTION TIME, MEASURE FROM WHERE THE P WAVE BEGINS UNTIL THE BEGINNING OF THE QRS , NORMAL INTERVAL IS 0.12 - 0.20 SECONDS( 3-5 SMALL BOXES)
QRS COMPLEX MIDDLE UPWARD DEFLECTION, R-WAVE,INDICATES THE VENTRICULAR DEPOLARIZATION , QRS IS LARGER BECAUSE OF LARGER TISSUE MASS, MEASURE FROM END OF P to end of S NORMAL IS 0.06-0.12 SECONDS
T-WAVE INDICATES REPLOARIZATION OF THE VENTRICLES, SLIGHTLY ASSYMETRICAL UPWARD DEFLECTION , NOTE IF THEY HAVE DOWNWARD OR POINTED DEFLECTIONS
Q-T INTERVAL INDICATES TIME OF VENTRICULAR ACTIVITY BOTH DEPOLAR AND REPOLAR, MEASURED FROM BEGINNING OF QRS TO THE END OF THE T-WAVE, NORMAL INTERVAL IS 0.36-0.44 SMALL BOXES (9-11 SMALL BOXES) RATE VARIES AMONG ADULTS CHILDREN ELDERLY
S-T SEGMENT REPRESENTS EARLY PART OF VENTRICULAR REPLOARIZATION, IS THE LINE THAT FORMS THE END OF QRS TO BEGINNING OF T- WAVE, NORMAL IS FLAT TO BASELINE.
PARTS OF A WAVEFORM P-WAVE, QRS COMPLEX, T- WAVE (sometimes a U-WAVE)
LOCATION OF WAVES ON WAVE FORM 1. P -WAVE 2.Q 3. R 4. S TOGETHER 5.T- WAVE 6. U-WAVE
BLACK MARKS AT TOP INDICATE 3 SECOND INTERVALS 1AND BEGINNING 2 MIDWAY 3 AT END OF PAPER,
WAVE FORM MOVEMENT AWAY FROMT HE ISOELECTRIC (BASE) LINE IN EITHER AND UPWARD OR DOWNWARD DEFLECTION
SEGMENT LINE BETWEEN 2 WAVE FORMS
INTERVAL A WAVEFORM PLUS A SEGMENT
COMPLEX SEVERAL WAVE FORMS
ECTOPIC BEATS BEATS OUT OF THE ORDINARY
REPOLARIZATION IS REPRESENTED BY THE T-WAVE
DEPOLARIZATION AND INITIATION OF IMPULSE IN SA NODE PRODUCE THE P-WAVE
MOST ACCURATE WAY OF ACQUIRING HEART RATE 1500 METHOD ; COUNT NUMBER OF SMALL SQUARES BETWEEN 2-R WAVES DIVIDE BY 1500 CAN NOT BE USED WITH IRREGULAR HEART BEATS
BIPOLAR STANDARD LEADS LEFT ARM POSITIVE RIGTH ARM NEGATIVE
LEAD AVR RIGHT ARM POSITIVE ALL OTHERS NEGATIVE
LEAD AVL LEFT ARM POSITIVE ALL OTHERS NEGATIVE
LEAD AVF LEFT LEG POSITIVE ALL OTHERS NEGATIVE
UNIPOLAR PRECORDIAL LEAD V1 POSITIVE LEAD LEFT OF STERNAL BORDER V2-V6 LEFT OF STERNAL BORDER
CARDIAC INFARCTION DEATH OF CELLS TO THE HEART MYOCARDIAL, EPICARDIAL, ENDOCARDIAL
CARDIO OF OR PERTAINING TO THE HEART
TECHNICIAN PERSON PERFORMING THE EKG TEST
ELECTRODES PAPER, FOAM , PLASTIC PADS THAT ADHERE TO THE PATIENT'S SKIN WHEN PERFORMING AN EKG TEST, THEY ATTACH TO THE LEADS OF THE MACHINE AND HAVE COLOR CODED CABLES FOR RECIEVING ELETRICAL IMPULSES OF THE HEART (SOMETIMES)
E K G PROTOCOL STEPS FOR ADMINISTERING AN E K G TEST, INTRODUCE YOURSELF, VERIFY PATIENT NAME ADN DOB, ASK DO THEY HAVE ANY QUESTIONS AND SO ON.....
