1
Q
conduction in atrial flutter
A
2:1 conduction

A
positive in Lead I
down in lead III, aVF, lead II
3

normal EKG
A
Lead I: positive Lead II: positive Lead III: positive aVR: negative aVL: slightly positive aVF:positive V1: negative V2: negative V3: positive V4: positive V5: positive V6: positive
4
Q
trivesicular block
A
LAFB
RBBB
1st degree

Q
tomb stone T waves
A
bad
-could mean occlusion of left anterior artery
