1
Q

The most striking feature of this electrolyte imbalance is the peaked T waves it creates; the P wave may also be flattened down

A

hyperkalemia

2
Q

This electrolyte imbalance presents with a U wave

A

Hypokalemia

3
Q

A shortened QT interval is what kind of electrolyte imbalance?

A

hypercalcemia

4
Q

This electrolyte imbalance is known to create a prolonged QT interval

A

hypocalcemia

5
Q

a large S wave in lead I, ST depression in II and large Q wave in III with T wave inversion is characteristic of what finding?

A

pulmonary embolism

6
Q

True or False: Q wave formation does occur in pericarditis

A

false

7
Q

This can cause ST segment elevation and T wave flattening or inversion

A

pericarditis

8
Q

What leads do you look for LBBB in?

A

V5 and V6

9
Q

What leads do you look for RBBB in?

A

V1 and V2

10
Q

this syndrome is classified as having a downward slope in V1 and V2 +RBBB +ST elevation

A

Brugada syndrome

11
Q

What is the difference between an old MI and a new MI if they both have Q waves?

A

ST elevation=new

Q waves without elevation= old

12
Q

What are the anterior leads?

A

V1-V4

13
Q

What artery corresponds with the anterior leads?

A

LAD

14
Q

What are the lateral leads?

A

AvL, I

15
Q

What artery corresponds with the lateral leads?

A

left circumflex

16
Q

What are the inferior leads?

A

II, III, AVF

17
Q

What artery corresponds with the inferior leads?

A

mostly RCA

18
Q

What are the posterior leads?

A

V1, V2

19
Q

What artery corresponds with the posterior leads?

A

RCA

20
Q

in ventricular hypertrophy, the axis gets placed toward or away from the hypertrophy?

A

toward

21
Q

In an infarct, the axis gets displaced toward or away from the infarct?

A

away

22
Q

What axis do you look at to determine deviation?

A

lead I and AvF

23
Q

Downward QRS in both lead I and AVF are indicative of what?

A

extreme RAD

24
Q

an up-going QRS in lead I and a down going QRS in AVF is called what?

A

LAD

25
Q

a downward QRS in lead I and an upward QRS in AVF is called?

A

RAD

26
Q

What leads serve as the “transition zone”?

A

V3 and V4

27
Q

What if you have an early transition in V1 and V2?

A

rightward rotation

28
Q

What if you have an later transition after V3 and V4?

A

leftward rotation

29
Q

Define ischemia

A

T wave inversion

30
Q

Define injury

A

ST elevation

31
Q

Define infarction

A

Q wave (which indicates necrosis or dead tissue)= infarction
