ACTION POTENTIAL
MEASUREMENT OF THE DIFFRENCE BETWEEN ELECTRICAL CHARGES NON EITHER SIDE OF THE CELL MEMBRANE
INDICATES THE PROBABILITY OF AN ELECTRICAL CHARGE WILL BE DICHARGED
POLARIZATION
PERIOD OF TIME WHEN CELL MEMBRANE IS RESTING
DEPOLORIZATION
THE PERIOD OF TIME WHEN IONS OR ELECTROYLYTESARE EXCHANGED THRU A SEMIPERMABLE MENBRANE AND A ELECTRICAL CURRENT IS DISHARG
ED
REPOLORIZATION
PERIOD OF TIME WHEN ELECTROLYTES MOVE BACK THRU THE CELLULAR MENBRANE AND A RESTING STATE IS REESTABLISHED
RESTING STATE OB EKG
VISIBLE ON BASELINE ALSO CALLED ISOELECTRIC LINE
WAVEFORM IS INDICATED BY ON A EKG
MARKED BY A DEPARTURE AWAY FROM BASE LINE
END OF WAVEFORM IS INDICATED BY WHAT ON A EKG
MARKED BYTHE RETURN TO BASELINE
WHAT IS ISOELECTRIC LIONE
THE BASELINE THE REFRENCE POINT
FOR DETERMINING BEGINNING AND END OF A WAVEFORM
WHAT DOES THE P-WAVE INDICATEON AN EKG
WAVEFORM INDICATES ATRIAL DEPOLORIZATION SYSOLE CONTRACTION
WHAT IS QRS WAVEFORM ON A EKG
COMES AFTER P AND INDICATES VENTRICULAR REPOLORIZATION(CONTRACTION OF VENTRICLES ) SYSTOLE
WAHT IS T WAVE ON A EKG
WAVE FORM INDICATES VENTRICULAR
REPOLORIZATION OCCURRS AFTERQRS
(VENTRICULAR RELAXATION )DYSTOLE
WHAT IS REFRACTORY PERIOD
TIME DURING REPOLORIZATION(RESTING DYSTOLIC)
WHEN CARDIAC CELL CANNOT RESPOND TO ANOTHER ELECTRICAL IMPULSE-OCCURS RIGHT AFTER THE QRS WAVE AND DURING MOST OF THE T WAVE
WHAT IS A U WAVE ON AN EKG
A SMALL ROUNDED WAVE THAT MAY BE VISIBLE ON EKG AFTER T WAVE AFTER T WAVE OR U WAVE GOES BACK TO BASE LINE TO INDICATE REST BEFORE CYCLE STARTS AGAIN
WHAT DOES ONE P WAVE AND QRS WAVE REPRESENT
A HEARTBEAT
ATRIA DEPOLORIZATION IS INDICATED BY WHAT ON EKG
P-WAVE
WHAT IS ATRIAL DEPOLORIZATION ON A EKG
A P WAVE
WAHT IS VENTRICULAR DEPOLORIZATION ON A EKG
QRS WAVE
WHAT IS THE VENTRICULAR REPOLORIZATION ON A EKG
T-WAVE
WHAT IS THE POLORIZED STATE ON EKG REPRESENT
THE BASE LINE RESTING PERIOD
WHAT IS PR INTERVAL
TIME PERIOD FROM THE ONSET OF THE P-WAVE TO THE BEGINNINBG OF THE Q WAVE
WAHT IS PR SEGMENT
WHEN WAVEFORM GOES TO BASE LINE AND ENDS WEHN THE NEXT WAVE STARTS THE P STARTS WHEN P MWAVE ENDS AND BEFORE Q STARTS
WAHT IS A QT INTERVAL
START OF Q TO THE END OF T
ELECTRODES
P/U ELECTRIC CURRENT OF HEART THRU SKIN
CONNECT ELECTRODE TO EKG MACHINE
LEAD
AMPLIFIER
INCREASE CURRENT GENERATED BY THE HEART
GALVANOMETER
CONVERT THIS ELECTRICAL CURRENT TO MECHANICAL CURRENT
STYLUS
NEEDLE OF THE EKG MACHINE NEEDLE IS HEATED THRU ELECTRICAL CURRENT AND MELTS THE PLASTIC COATEING ON EKG PAPER TO FORM WAVES
HORIZONTAL LINE ON EKG
REPRESENTS TIME -DURATION OF EVEMT
25MM/SEC
VERTICALE LINE
POWER AND STRENGHTH
MEASUREMENT OF BOXES
BIG BOXES 5 MM BY 5MM
AN 1 MV EQUALS 1O SMALL SQUARES
