Q

What is GTN?

A

It’s a potent venodilator, dilates peripheral blood vessels thereby reducing venous return to the heart

Q

Why is the use of GTN contra’d in suspected inferior or right ventricular infarcts?

A

As these patients may not be able to compensate for the drop in venous return.

16
Q

Signs and symptoms of SVT are:

A
  • Tachycardia
  • Persistent or severe chest pain
  • SOB with crackles
17
Q

When should immediate synchronised cardioversion be performed?

A

When Pt is unconscious or becoming unconscious

18
Q

What can MICA administer to slow down Heart rate?

A

Adenosine (6mg then 12mg x 2)

19
Q

What does adenosine do?

A

It slows down conduction through the AV node

20
Q

When should the valsalva manoeuvre be performed?

A

When SVT is confirmed and BP is over 100mmhg.

21
Q

How is an abdominal valsalva performed?

A

Position the patient supine.

Get pt to blow hard enough to move the plunger for 15 seconds if tolerated

22
Q

How many times should the valsalva be performed?

A

Repeat twice 2 minutely

Max 3 attempts.

23
Q

Pts with SVT showing signs of ectopic activity, what is administered?

A

O2 therapy.

24
Q

What are components of VT?

A 
QRS >0.12
> 30sec VT
Rate >100
Mostly regular
Av node dissociation, no p waves
25
Q

What do MiCA administer to stabilise VT?

A

Amiodarone

26
Q

What does Amiodarone do?

A

It’s an anti-arrhythmic agent, stabilises VT

27
Q

Why can accelerated idioventricular rhythm be associated with?

A
  • post arrest patients
  • AMI
  • Drug toxicity
  • Post adrenaline admin
28
Q

What are some features of the idioventricular rhythm?

A

Regular rate, 50-110bpm
3 or more ventricular complexes
QRS >0.12

29
Q

Rates of AIVR distinguish it from other rhythms of similar morphology, what are the other rhythms?

A

Below 50bpm- Ventricular escape rhythm

Above 110bpm- VT

30
Q

What are the cardiogenic caused of APO?

A

Left ventricular failure
Congestive cardiac failure
Liver/renal failure= fluid overload

31
Q

What are the non cardiac causes of APO?

A

Smoke inhalation
Near drowning
Anaphylaxis

32
Q

How are the non cardiac causes of APO treated?

A

No Nitrates, just O2 therapy

33
Q

What is the treatment for cardiogenic APO?

A
  • Nitrates if basal and midline crackles

- Nitrates and CPAP/assisted vents 100% if full field crackles
