Question 4: On the ECG tracing, the place at which the
depolarization is complete, and repolarization starts is known as
the:
A. QRS complex
B. P wave
C. J point
D. PR interval
Answer:
C. J point


Question 5: When you evaluate the rhythm of an ECG tracing,
which BEST describes what you are doing?
A. Calculating the heart rate for the atria and the ventricles based on
whether they are regular or irregular.
B. Determining the regularity by measuring the P-P and R-R intervals

complex and the other on the J point.
Answer:

,B. Determining the regularity by measuring the P-P and R-R intervals in
a 10-second strip.

a result of:
