Ventricular Tachycardia
CPR, Defibrilate, amiodarone, epi - ANSWER✔✨-What is this rhythm and how is it treated?
Ventricular fibrillation
CPR, Amiodarone, Defibrilate, Epi - ANSWER✔✨-What is this rhythm and how is it treated?
Asystole
CPR & Epinephrine - ANSWER✔✨-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) - ANSWER✔✨-What is this rhythm? and how
is it treated?
AFib
"control the rate and anticoagulate"
Synchronized Cardioversion and anticoagulation - ANSWER✔✨-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 - ANSWER✔✨-How is stable Afib treated?
AFib RVR
This is Afib plus tachycardia and it is treated as unstable Afib
Cardiovert - ANSWER✔✨-What is this rhythm? and how is it treated?
30% - ANSWER✔✨-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 - ANSWER✔✨-What does Cardizem/Diltiazem
do?
1. Protamine
, 2. Vitamin K
3. if there is an active bleed or they are going to need surgery - ANSWER✔✨-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 - ANSWER✔✨-what are the steps to BLS CPR?
2 leads ds - ANSWER✔✨-How many leads must Asystole be confirmed in?
Vasoconstrictor and (+) Inotrope - ANSWER✔✨-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 - ANSWER✔✨-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
