Which of the following can be determined by lead II cardiac monitoring?
A) Positive deflection
B) Chamber enlargement
C) Axis deviation
D) Presence of a myocardial infarction, but not its location

Question

Quizplus · Accepted Answer

Lead II monitoring can determine positive deflection, which refers to the upward movement of the ECG curve when the electrical activity moves towards the particular electrode.

Answer: B
 Lead II monitoring can also determine chamber enlargement, which can be indicated by changes in the amplitude and duration of the QRS complex.

Answer: C
 Lead II monitoring cannot determine axis deviation since it requires a combination of multiple leads to evaluate the heart's electrical axis.

Answer: D
 Lead II monitoring cannot determine the location of a myocardial infarction, only its presence. A combination of multiple leads is required to determine the location.
