Question
Answer
EQUIPMENT   Electrodes/ sensors  
Electrodes   Plastic strips  
Plastic strips   Attach 10 to PTs skin they help in conduction of current from PTs body to EKG MACHINE THEY HAVE ELECTROLYTE GEL - helps in conduction  
Alcohol swabs   Cleaning the skin from oil and dirt or lotions and if PT has ( diaphoresis) excessive sweat  
Absorbs sweat with   Gauze and then cleanse with alcohol swab Sometimes sand paper  
Disposable razors   Remove hair for testing  
Leads   Is the passage of currant from one electrode to another ( this shows the motion on the stylus paper  
12 lead EKG   10 sensors on PTs body Electrodes----4 limbs -----6 chest  
6 limb 3 standard   3 standard limb leads ( bipolar leads) Needs 2 points to get complete ( pt to pt )  
6 limb 3 augmented   3 augmented limb leads ( unipolar)  
6 chest leads   V1 ----- v6 Precordial leads  
Vector   Arrows that shows direction of the flow or the current  
Leads 6 limb 6 standard   Standard limb leads always in Roman numerals l , ll , lll  
3 augmented limb leads   AVR/ RT AVL /Lf AVF/ foot  
AVR/AVL/ AVF ( AV STANDS FOR AUGMENTED VOLTAGE)   AV STANDS FOR AUGMENTED VOLTAGE INCREASE= augmented voltage  
Roman numeral # 1 ( standard )   Is between RA and LA  
Roman numeral # 2 ( standard )   Is between RA and LL  
Roman numeral # 3 ( standard)   Is between LA and LL  
Precordial lead   6 chest leads v1 threw v6  
AVR / right   From the midpoint LA and LL TOWARDS the RIGHT ARM  
AVL /left   From the midpoint of RA and LL TOWARDS THE LEFT ARM  
AVF/ foot   From the midpoint of the RA and LA TOWARDS LEFT LEG  
RL / right leg   Is a ground not taking part in the leads  
Chest leads V1 RED   V1 = 4th intercostal space ( ICS) RIGHT SIDE OF STERNUM  
Chest leads V2 YELLOW   V2= 4th (ICS ) LEFT SIDE OF STERNUM  
Chest leads V3 GREEN   V3 = IS BETWEEN V2 and V4  
Chest leads V4 BLUE   V4 = is 5th ( ICS) LEFT SIDE OF MIDCLAVICULAR LINE  
Chest leads V5 ORANGE   V5 = 5th ( ICS) LEFT SIDE ANTERIOR AXILLARY LINE  
Chest leads V6 PURPLE   V6 = 5th (ICS) LEFTSIDE MID AXILLARY LINE ( BY BACK SIDE)  
12 leads =   10 electrodes passing of current  
RA COLOR   Right arm = WHITE  
RL COLOR   Right leg = GREEN ( GROUND)  
LA COLOR   Left arm = BLACK  
LL COLOR   Left leg = RED  
V1 color ( traffic light)   RED Short red placed at 4th ( ICS) right side of sternum  
V2 color (Traffic light)   YELLOW Is placed at 4th (ICS) Left side of sternum  
V3 color ( traffic light)   GREEN Short green placed at V2 and V4  
V4 color ( bop )   BLUE Is placed at MIDCLAVICULAR line  
V5 color ( bop)   ORANGE Placed at anterior AXILLARY line  
V6 color ( bop )   PURPLE Placed at midaxillary  
What are the colors of the first 4 and where are they placed   ( RL / GREEN) ( LL / RED) ( RA/ WHITE) ( LA / BLACK)  
Which is the ground wire   RL = GREEN  
Name the 3 standard limb leads   ROMAN NUMERALS 1/2/3  
Standard leads are   BIPOLAR  
Name the 3 augmented leads   AVR / AVL / AVF  
Augmented leads are   Unipolar  
Another name for the chest leads   Pre Cordial  
Artifacts   Tracings on the EKG paper that is not coming from the PTs heart  
Normal patient position for performing an EKG   SUPRINE  
If the patient has a head injury raise the   Bed to 30% angle  
If the patient is having trouble breathing raise the   Bed to 45% angle  
This layer of the skin is composed of living cells and is needed to detect Electrical signals for the EKG   The dermis  
Clinical term for sweating profusely   Diaphoresis  
PTs with Diaphoresis need to be cleaned with   Wipe with gauze and then cleanse skin with with alcohol swab  
Interference on the EKG NOT COMING FROM THE PT is called   ARTIFACTS/ AC INTERFERENCE  
Who must recognize the ac interference and correct it   The MA  
What causes a WANDERING BASE LINE   Loose electrodes/too little gel / too much hair  
What does a wandering base line look like   Uneven baseline  
How do you fix a wandering base line   Check all electrodes  
What is a SOMATIC TREMOR   Muscle movement (Voluntary-- laugh sneeze moves) ( unvoluntary ----Parkinson's) If Parkinson's place electrodes on torso  
What does a SOMATIC TREMOR LOOK LIKE   Unnatural baseline / deflection/ j├Ągered peaks  
Voluntary SOMATIC TREMOR HOW DO YOU FIX   Check for dangling arms / legs -- make PT COMFORTABLE--- room temp PT IS SHIVERD  
Involuntary SOMATIC TREMOR HOW DO YOU FIX   Parkinson's PT s put electrodes on torso  
What causes a 60 second interference   Frayed wires / crossed wires / or other electrical equipment  
What does a 60 second interference look like   Small fuzzy lines  
How do you fix a 60 second interference   Check all wires and all electrodes  
What causes an interrupted baseline   Detached electrodes  
What does interrupted baseline look like   Breaks between complexes  
How do you fix an interrupted baseline   Check all electrodes  
.AC INTERFERENCE   AC = ALTERNATING CURRENT  
If you see interference on leads 1 & 111 , which sensor Or electrode would you check   LA  
If you see interference on leads 11 & 111, which sensor Or electrode would you check   LL  
If you see interference on leads 1&11, which sensor or Electrode would you check   RA  
If you see interference on leads 1&AVR which sensor or Electrode would you check   RA  
If you see interference on leads 11. & AVF which sensor or Electrode would you check   LL  
If you see interference on leads 111 & AVL which sensor or electrode Would you check   LA  
If you found interference on leads 1&111 what other lead will most likely have interference   AVL  
If you found interference on leads 11&111 which other lead will most likely have interference   AVF  
ANTERIOR   FRONT  
POSTERIOR   BACK /BEHIND  
SEPTAL   Pertaining to the septum ( heart )  
SUPERIOR   ABOVE  
INFERIOR   BELOW  
APICAL   PERTAINING TO THE APEX ( 5th ICS LEFT SIDE)  
LATERAL   SIDE  
This is determined by measuring the R-R INTERVALS ACROSS THE ENTIRE RHYTHM STRIP   RHYTHM  
If the R-R Intervals all measure the same the   The RHYTHM is termed REGULAR  
Which lead is placed at the 4th ICS RT SIDE OF THE STERNUM   V1 - RED  
Which lead is placed at the 4th ICS LEFT SIDE OF THE STERNUM   V1- YELLOW  
Which lead is placed between V2 & V4   V3 - green  
Which lead is placed at the 5th ICS LEFT SIDE OF MIDCLAVCAL LINE   V4- BLUE  
Which lead is places at the 5th ICS LEFT SIDE ANTERIOR AXILLARY LINE   V5- ORANGE  
Which lead is placed at the 5th ICS LEFT SIDE MIDAXILLARY LINE   V6- PURPLE
