18
Q

QT wave should be between :

A

0.32-0.40

19
Q

A prolonged QT can lead to what ekg rhythm
**Hypomag can cause this

20
Q

ST elevation is tissue _______

A

death

21
Q

ST depression is tissue __________

A

ischemia

22
Q

What is a normal HR

A

60-100

23
Q

What medication should be given slow IVP for symptomatic bradycardia

A

Atropine

24
Q

Sinus Tach golden rule =

A

treat the cause!

25
Q

What medication is given for SVT?

A

Adenosine - this stops heart, push quickly- IV must be close to the heart

26
Q

What are other treatments for SVT?

A

Synchronized cardioversion, ablation, vagal maneuvers

27
Q

Electrical impulse starts in the atria but not the SA node. A premature impulse before the SA fires is known as what?

A

Premature Atrial Contraction (PAC)

28
Q

How do you treat a new diagnosis of A-flutter?

A

Adenosine
Cardioversion

29
Q

How do you treat an old diagnosis of A-flutter

A

Anticoags
Cardioversion
Antiarrhythmic (amiodarone)

30
Q

What medication treats atrial and ventricular arrhythmias?

A

Amiodarone

31
Q

How does amiodarone work?

A

Prolongs repolarization

32
Q

What are the common treatments for Afib?

A

Cardioversion
Anticoags
Antiarrhythmics
Beta-blocker/Calcium Channel blocker

33
Q

A timed delivery of electrical current through a defibrillator is known as what?

A

Cardioversion

34
Q

What is a commonly used antiarrhythmic for Afib?

A

Digoxin

35
Q

_________ rhythms signal in the AV node, not the SA. If symptomatic, you should treat it like sinus brady

A

Junctional

36
Q

A patient who has ventricular fibrillation has no pulse (TRUE OR FALSE)

A

TRUE - start CPR. Defib ASAP
