Ventricular Tachycardia

CPR, Defibrilate, amiodarone, epi - CORRECT ANSWERS-What is this rhythm and how
is it treated?

Ventricular fibrillation

CPR, Amiodarone, Defibrilate, Epi - CORRECT ANSWERS-What is this rhythm and
how is it treated?

Asystole

CPR & Epinephrine - CORRECT ANSWERS-What is this rhythm? and how is it
treated?

PVC or premature ventricular contraction

Treat the underlying cause:
1. hypoxemia (o2)
2. Ischemia (12 lead to confirm)
3. electrolyte imbalance (Mg+ or K+ replacement) - CORRECT ANSWERS-What is this
rhythm? and how is it treated?

AFib
"control the rate and anticoagulate"

Synchronized Cardioversion and anticoagulation - CORRECT ANSWERS-What is this
rhythm and how is it treated if unstable?

Give an antidysrhythmic (amiodarone)
Cardizem/Diltiazem

,We don't defib because we are worried a clot has formed in the appendages which will
travel to the brain or lungs when shocked - CORRECT ANSWERS-How is stable Afib
treated?

AFib RVR

This is Afib plus tachycardia and it is treated as unstable Afib
Cardiovert - CORRECT ANSWERS-What is this rhythm? and how is it treated?

30% - CORRECT ANSWERS-What percent of cardiac output is lost due to Afib and
loss of "atrial kick"?

this is a calcium channel blocker it decreases BP & decreases HR it is often given to
help reduce the HR in Afib RVR along with Heparin/Warfarin - CORRECT ANSWERS-
What does Cardizem/Diltiazem do?

1. Protamine
2. Vitamin K
3. if there is an active bleed or they are going to need surgery - CORRECT ANSWERS-
What is the antidote for heparin?
What is the antidote for Warfarin?
When do we reverse anticoagulation?

1. recognition of sudden cardiac arrest ck for pt responsiveness and breathing
2. Activate the emergency response system (call a code or rapid)
3. CPR if no pulse, and while waiting on the crash cart to arrive. (Remember 30
compressions to 2 breaths)
4. Defibrillate- as soon as possible - CORRECT ANSWERS-what are the steps to BLS
CPR?

2 leads ds - CORRECT ANSWERS-How many leads must Asystole be confirmed in?

Vasoconstrictor and (+) Inotrope - CORRECT ANSWERS-what is Epinephrine?

pacer spikes with no P or QRS

Usually a problem with battery or lead in the wrong place. the PM fires but doesn't
cause a contraction

use an external pacemaker and call the Dr.

Turn up the the miliamps - CORRECT ANSWERS-What is failure to capture on a
pacemaker?

The PM is unable to sense where or when the heart is depolarizing or repolarizing and
delivers spikes at an inappropriate time

, Pacer rep needs to be called to interrogate the PM - CORRECT ANSWERS-What is
failure to sense?

this is called a R on T phenomenon
Causes vtach or torsades de point - CORRECT ANSWERS-What happens if pt is
shocked mid repolarization between the S-T?

CO= HR x SV - CORRECT ANSWERS-What is the cardiac output formula?

CO- 4-6
pink warm and dry
>30 ml/hr UO
SBP >90
AOx4
MAP >60
Skin perusing cap refill <2second - CORRECT ANSWERS-What are signs and
symptoms that cardiac output is good?

CVP 2-6 mmHg

Hypo/hypervolemic - CORRECT ANSWERS-What is the range for CVP?

signs of hyper/hypovolemia

hypovolemic=
skin tenting & dry mucous membranes
decreased CVP < 2

Hypervolemic=
Fluid overload/edema
increased CVP >6 - CORRECT ANSWERS-What are signs and symptoms of a preload
problem?

- if hypovolemic give fluids, albumin, blood
-if hypervolemic give a diuretic - CORRECT ANSWERS-How are CO problems related
to Preload/SV treated?

1. is CO low?
2. Did the HR change?
3. Preload: What is CVP? hypo/hypervolemic s/s?
If normal move on...
4. Afterload, what is their BP? High or low?
if normal must be contractility...
5. (+) inotrope needed to increase contractility - CORRECT ANSWERS-What are the
steps to determine the cause of low cardiac output?
