WHAT IS A SENSOR
DISC OR TAB MADE OF PLASTIC OR METAL PLACED ONT PT CHEST TO P/U ELECTRICAL ACTIVITY THRU CABLES
ALSO CALLED ELECTRODE
WHAT IS A LEAD
A CONFIGURATION OF POSITIVE AND
NEGATIVE SENSORS ON THE BODY SURFACE THAT P/U ELECTRICAL INFO FROM THE HEART
CABLE
ONE OR MORE INSULATED WIRES THAT CONNECT SENSORS TO AN ELECTROCARDIOGRAPH
GLAVANOMETER
DEVICE IN EKG MACHINE THAT DETECTS ELECTRICAL CURRENTS FROM PT AND CONVERTS IT TO MECHANICAL ENERGY ,WHICH IS THEN RECORDED ONTO GRAPH PAPER
STYLUS
NEEDLE OF EKG MACHINE THAT FORMS A TRACING ON THE GRAPH PAPER
CALIBRATION
PROCESS OF SETTING A MACHINE TO A STANDERIZED SCALE
ARTIFACT
ADDITIONAL ELECTRICAL ACTIVITY ON A N EKG
HORIZONTAL LINE ON EKG
MEASURE TIME 1 LARGE BOX =.,20 0F A SEC OR 25MM PER SEC OR 5 LARGE BOXES PER SECOND
VERTICAL LINE ON EKGA
MEASURE VOLTAGE/ STRENGTH 1 CM -1 MV OR 2 LARE BOXES(10 SMALL BOXES =1 CM
ISOELECTRIC LINE
BASE LINE ON AN EKG REPRESENTS AN ABSCENCE OF ELECTRICAL ACTIVITY
LEAD PLACEMENT
10 SENSORS ARE ATTACHED TO PT TO GET A 12 VIEW OF THE HEARTS
3 TYPES OF LEADS
STANDARD LIMB LEADS ,AUGMENTED HAIR, PRECORDIAL LEADS
LIMB LEADS A RE ATTACHED?
ARE BI-POLAR AND ARE ATTACHED RT ARM, LFT ARM RT LEG LEFT LEG
AUGMENTED LEADS
ARE UNIPOLAR LEADS THREE AUGMENTED LEADS MAKE USE OF 3 ACTIVE SENSORS TO RECORD 3 ADDITIONAL VIEWS
