18
Q

What are signs of hyperkalemia

A

flattened/widened P waves
Widened QRS
Peaked T waves

19
Q

what are sings of hypokalemia

A

flattened T waves

prominent U waves

20
Q

what are signs of hypercalcemia

A

shortened QT interval

widened T wave

21
Q

what is the normal PR interval

A

.2 mm (one small box)

22
Q

what is normal QRS duration

A

.12

23
Q

What are sings of hypocalcemia

A

prolonged QT interval

flattened T wave

24
Q

how does hypothermia appear on EKG

A 
severe sinus bradycardia
prolonged PR interval
Widened QRS complex
prolonged QT interval
**extra deflection at end of QRS
25
Q

How do you differentiate eleavated STs from MI and pericarditis

A

pericarditis has elevated ST in all leads

pericarditis also has PR depression

26
Q

What does the term paced rhythm mean?

A

sharp depolarizations
unable to interpret anything beyond that it is a paced rhythm
can be atrial, ventricular or AV sequential

27
Q

What are signs of brugada syndrome

A

EKG with RBBB and persistent ST segment elevation V1-V3

28
Q

what is the normal length of Bazetts formula

A

0.44 seconds

29
Q

What does a ventricular rhythm look like

A

no p waves

wide QRS complexes

30
Q

what are bigeminal, trigeminal or quadrigeminal beats

A

series-pattern of ectopic depolarizations

either atrial or ventricular in origin

31
Q

narrow QRS complexes are indicative of what

A

supraventricular rhythms

32
Q

If all P waves are different shapes with irregular ventricular rhythm what is beat

A

wandering pacemaker

33
Q

how do you differentiate atrial fibrillation and flutter

A

flutter has more of a rhythm

34
Q

what are delta waves found in

A

wolf parkinson white

35
Q

normal rhythm but with a prolonged PR interval consistently signifies what type rhythm

A

first degree AV block

36
Q

if you see p waves without QRS complex what could it be

A

Type I- wenckebach second degree block

Type II mobtiz second degree block

37
Q

what is a wenckebach pattern

A

progressively prolonged PR intervals with subsequent dropped beat

38
Q

What is mobtiz second degree block

A

normal PR interval with a widened QRS

2 p waves one response, 3 p waves one response

39
Q

vagal maneuvers help clear up what type of second degree block

A

mobitz

40
Q

what is a third degree block

A

normal p sinus rhythm, absolutely no correlation with ventricles
