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/ jägered 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 |
