EXAM FULL QUESTIONS WITH
SOLUTIONS GUARANTEED TO PASS
wandering baseline. Ans: appears when the contact between the
electrode and skin is impeded
⫸ v1. Ans: 4th intercostal space (ICS) R of sternum
⫸ V2. Ans: 4th ICS, l of sternum
⫸ v3. Ans: between v2/v4
⫸ v6. Ans: 5th ICS, midaxillary
⫸ v5. Ans: 5th ICS between v4/v6
⫸ positive. Ans: a wave that exists above the isoelectric line.
⫸ negative. Ans: a wave that exists below the isoelectric line.
, ⫸ t wave symmetry. Ans: t wave symmetry is defined as a t wave
that is symmetrical with the respect to the y axis. A t wave whose
right and left sides form mirror images on the vertical acs are said the
exhibit symmetry.
⫸ p wave symmetry. Ans: p wave symmetry is defined as a p wave
that is symmetrical with respect to the y axis. p wave whose right and
left sides form mirror images on the vertical axis are said to exhibit
symmetry
⫸ amplitude of a wave. Ans: measured using the horizontal grid
lines on the ekg. each small square is 1mm tall.
⫸ PR. Ans: 0.12 tp 0.2 seconds
⫸ QRS. Ans: 0.04 to 0.10 seconds
⫸ p wave. Ans: electrical activity asociated with the SA node
impulse and depolarization of the atria
⫸ PR wave. Ans: represents the time it takes for the SA node to dire,
atria to depolarize and the electricity to travel through the AV node.
⫸ QRS complex-. Ans: represents the time is takes for the ventricles
to depolarize. measured from the end of the pr intraval to the j point
