Week 2 Flashcards
EKG should be performed using what?
Standard procedure for this course we will be using 8 steps
What is the 8 step procedure are we using for EKG interpretation
1) Rhythm
2) Rate
3) P Wave
4) ST Segment
5) PR interval
6) QRS interval
7) T wave
8) QT interval
What wave doesn’t every CC or cardiac cycle have
Q wave
Sinus rhythm consist of?
PQRST
What do examine on the EKG strip for ventricular rhythms?
For ventricular rhythms examine R to R intervals
For the atrial rhythm, observe the
P-P intervals and ask are they regular
How do you determine the rate?
There are several methods we:
Count the number of QRS complexes over a 6 second interval
Multiply by 10 to determine heart rate
Are heart rate and pulse the same
Yes
Represents atrial depolarization
P Wave
Atrial deplorarization means to
Means to contract
In a normal EKG, the P-wave precedes
The QRS complex
How does the P-wave look
Like a small bump upwards from the baseline
P-wave begins until
The beginning of the QRS complex
_____________Marked paper or counting small boxes method can be used to determine _______________
Calipers, PR intervals.
The methods used to determine PR intervals is. Or ally this interval
0.12 to 0. 20 seconds (3-5 seconds)
How do you count this interval 0.12 to 0.20 seconds
0.04 little box
x 5 reason why or how big wave is counted
__________
0.20 big box
What complex indicates ventricular depolarization?
QRS
The QRS complex indicates
Ventricular depolarization
What does depolarization trigger?
Depolarization triggers contraction of the ventricles.
What wave indicates repolarization?
T wave
The T wave indicates
The repolarization of the ventricles
The T waves is a
Slightly a symmetrical, wave form that follows after a pause, the QRS complex.
Ventricles are starting to relax again when?
T-wave
Represents the time of ventricular activity including both depolarization and repolarization.
QT
