Flashcards in Axis Deck (11):
The position of the mean QRS vector
Points downward and to the left
To determine axis deviation look at which leads
Lead I and AVF
In lead I if the QRS is mainly positive (above the line) then the mean QRS axis points...
To the left. Towards the positive electrode on the patients left arm
In the AVF lead if the QRS is mostly positive (upright) then the mean QRS vector is pointing...
Down towards the positive electrode on the patients left foot
If the QRS in lead I is mostly negative (below the baseline) then the mean QRS vector points
To the right towards the negative electrode on the patients right arm. This is known as right axis deviation
If the QRS is positive in lead I and negative in AVF this is...
Left axis deviation
When the isoelectric QRS has rotated to leads V1 and V2 this is known as
When the isoelectric QRS is found in leads V5 and V6 this is known as
Axis deviation is in the
