The flashcards below were created by user Jcolon1895 on FreezingBlue Flashcards. What would you like to do?


  1. Angina

    N+V

    Angina- tightness in the heart/chest

    N+V- Nausea/Vomiting

    Emesis- Vomiting
  2. Code Blue

    ICS
    Code Blue- when a patient is dead or dying

    STAT- assistance is needed right away/immediately

    AED- Automatic external defibrillator

    ICS- Intercostal space. Space between the ribs
  3. What equipment is needed when performing an ECG?
    • 1. EKG machine
    • 2. EKG paper
    • 3. Plug
    • 4. Lead wires
    • 5. Electrudes
    • 6. Alchohol
    • 7. Gloves
    • 8. Pens
    • 9. Gown
  4. Standard precautions

    Isolation precautions
    Standard precautions- wash hands and wear gloves

    Isolation precautions- patient may be contagious, must wear personal protective equipment
  5. HIPAA
    Health Insurance portability and accountability act (patients privacy)
  6. Dr. Waller

    Dr. Elthavon
    Dr. Waller- was the first doctor to perform an ECG on a human

    Dr. Elthavon- the creator of the ECG
  7. 4 Vital signs and the normal values
    Heart beat 60-100 beats per minute

    Blood pressure 120/80

    Temperature 98.7

    Pulse 16 bpm (normal between 12-20)
  8. MI

    EKG

    Arythmia

    Ischemia
    Myocardial Infarction

    Electrocardiogram- a picture of the electrical activity of the heart

    Arythmia- Abnormal heartbeat

    Ischemia- lack of oxygen
  9. 4 Layers of the heart
    Endocardium- inner layer

    Myocardium- middle layer

    Epicardium- outer layer

    Pericardium- outer sac
  10. The main function of the heart is to?
    Pump blood to and from the body, because the blood carries oxygen and carbon dioxide
  11. The cardiac out put is?
    • 5 liters per minute.
    • If the body does not produce this amount of blood the tissue will begin to die and in turn the patient will turn blue (cyanosis)
  12. What are the top, bottom  and middle of the heart called?
    Top- Base

    Bottom- Apex

    Middle- middle of the heart is called the septum
  13. CAD
    Coronary artery disease
  14. One way blood flow
    • 1. Superior and Inferior vena cava
    • 2. Right atrium
    • 3. Tricuspid valve
    • 4. Right ventricle
    • 5. Pulmonary semilunar valve
    • 6. Pulmonary trunk (blood vessels)
    • 7. Pulmonary arteries (blood vessels)
    • 8. Lungs O2 in and CO2 out (gas exchange)
    • 9. Pulmonary veins
    • 10. Left atrium
    • 11. Bicuspid/mitral valve
    • 12. Left ventricle
    • 13. Aortic semilunar valve
    • 14. Aorta
    • 15. Body
  15. The largest veins in the body?

    The largest arteries in the body?
    The largest veins in the body are the Superior and Inferior Vena Cava

    The largest artery in the body is the Aorta
  16. The right side of the heart has what kind of blood?

    The left side of the heat is composed of?
    Right side- deoxygenated

    Left side- oxygenated blood
  17. Oxygen is exchanged in two parts of the body, which ones?
    In the lungs and the capillaries
  18. Arteries carry?

    Capillaries carry?

    Veins carry?
    Arteries carry O2 oxygenated

    Capillaries carry O2 & CO2 oxygenated and deoxygenated

    Veins carry- DE O2 deoxygenated

    Exception to this rule is that the right and left pulmonary arteries are the only arteries that carry deoxygenated blood.

    Pulmonary veins are the only veins that carry oxygenated blood.
  19. Coronary circulation
    blood flow from the heart and back
  20. Cardiac cycle

    Systole

    Diastole
    is one heart beat. Its made up of a systole and a diastole

    Systole- contraction (its the higher number on top)

    Diastole- relaxation (lower number on the bottom)
  21. The two atria contract at the same time pumping blood into the 2 ventricles. (tricuspid and bicuspid valves open)

    The 2 ventricles contract at the same time pumping blood into the body and lungs. (pulmonary and aortic valves open)
    The two atria contract at the same time pumping blood into the 2 ventricles. (tricuspid and bicuspid valves open)

    The 2 ventricles contract at the same time pumping blood into the body and lungs. (pulmonary and aortic valves open)
  22. 4 Qualities and Definitions
    Automaticity- is the hearts ability to start an electric impulse on its own.

    Conductivity- is the hearts ability to receive and transmit electricity

    Contractility- is the hearts ability to shorten

    Excitability- the hearts ability to respond
  23. What do you tell the patient before performing an EKG on them?
    • 1. Identify yourself
    • 2. Identify the patient with 2 forms of ID
    • 3. Please stay still
    • 4. This will not hurt
  24. Wire colors and locations
    • Right arm- white
    • Right leg- green
    • Left arm- black
    • Left leg- red
    • Precordial chest- brown
  25. V1 through V6
    • V1 Right side 4th ICS- Near the sternum
    • V2 Left side 4th ICS- Near the sternum
    • V3 Between V2 & V4
    • V4 Left 5th ICS- Mid-clavicular line
    • V5 Left 5th ICS- Anterior axillary
    • V6 Left 5th ICS- Mid-clavicular
  26. What is the speed of the EKG paper?
    25mm per sec
  27. Einthovan's Triangle
    • Pic#1- Right arm (AVR) negative to left arm (AVL) positive

    Pic#2 Right arm negative to left leg (AVF) positive

    Pic#3 Left leg positive to left arm negative
  28. Mechanical and Electrical properties of the heart
    • P Wave
    • atrial depolarization- electrical
    • atrial contraction- mechanical

    • QRS complex
    • atrial repolarization- electrical
    • atrial relaxation- mechanical
    • ventricular depolarization- electrical
    • ventricular contraction- mechanical

    • Twave
    • ventricular repolarization- electrical
    • ventricular relaxation- mechanical
