QUESTIONS AND ANSWERS | ALREADY PASSED |

Leads II (parallel) & V1 (perpendicular; biphasic)
1) P wave > 2.5 mm in
R atrium enlargement?
II, III, aVF aka "p
pulmonale"
Precise axis determination? Look for most biphasic wave - it will be perpendicular to this.
RA enlargement, almost always related to pulmonary
p pulmonale?
system; usually causes backup into the ventricle &
atria, causing enlargement of atria
1) V1 terminal portion, P > 1mm below line
2) Terminal portion of P > 0.04
L atrium enlargement?
sec (1 small box) "p mitrale"
p mitrale LA enlargement due to mitral valve issue
1) R> S in V1
2) R progressively smaller from V1-V6

RVH - criteria 3) S > R in V6

- will cause right
axis deviation (also
tall R in III)
