Q

LPFB

A

RAD, R1Q3 down up up

17
Q

T wave inversion

A

ischemia in low o2 demand

18
Q

RVH is

A

increase R wave in V1 and V2

19
Q

Atrial Hypertrophy Right

A

Peaked T waves in I, II, or III Biphasic P wave in V1

20
Q

hypocalcemia

A

long QT

21
Q

Ischemia

A

Alt. Ventricular repolarizattion - ST segment despression and T waves. St depression: ischemia in high oxygen demain (coronary insufficiency) T wave inversion: due to acute a. obstruction in low O2 demand.

22

A

II, III, aVF

25
Q

LVH is

A

increased R waves in I, aVL, V5 and V6 or >11 in aVL, >12 in I, and >10 in aVF

26
Q

RBBB

A

A

LAD Q1R3 Up, down, down, with RBBB

28
Q

Q waves

A

necrosis; significant if >0.4 wide or 1/4 height of QRS

29
Q

what has no QRS

A

V fibrillation, asystole

30
Q

Left Atrial Hypertrophy

A

But shape in I, II, or III Bisphasic P wave in V1

31

A

ST elevation

34
Q

Posterior Infarction

A

ST depression in V1 and V2 Tall R, no Q
