RHYTHMS
What rhythm is described as having a consistently long P-R interval
First degree block
Used in symptomatic stable bradycardia
1 mg atropine?
First line of treatment for narrow complex stable SVT
attempt vagal maneuvers?
Patient presents unresponsive without detectable breaths. Cardiac monitor / AED is placed properly noting a wide complex tachycardic rhythm. What critical action is necessary?
check for a pulse
What rhythm is described as Irregularily irregular
Atrial fibrillation
First drug of choice in symptomatic stable SVT
6mg adenosine
Door to balloon time for STEMI
90 minutes
Name 2 venticular arrythmias you do not shock.
asystole and PEA
The depth of chest compression on an adult?
2 inches
When you can see an organized rhythm but feel no pulse
PEA
First drug of choice for pulseless v-tach or v-fib
1 mg epinephrine
The patient is having gasping respirations and is not responsive, what should be done
What is start CPR?
When cardiac arrest is witnessed and V-Fib presents, at what point should you defibrillate?
Immediately or as soon as a defibrillator is present.
How long should be spent on a pulse/rhythm check
5-10 seconds
When the P-R interval is long, longer, longer, until you drop a QRS complex
Wenkebach or 2nd degree type 1 HB
Second line drug for symptomatic bradycardia?
Dopamine at 2-20 mcg/kg/min
Torsades or polymorphic tachycardia
What is Magnesium 1g IV?
Name two ventricular rhythms that are shockable.
pulseless v-tach and v-fib?
When rate and breaths are rescue breaths delivered at?
1 breath every 5-6s = 10-12 breaths per min
Described as narrow complex, typically with a HR of 150bpm or greater.
SVT
Dose and drug of antiarrhythmic given for v-tach w/o pulses?
What is 300mg Amiodarone
A patient presents with Wide Complex tachycardia with pulses and a BP of 80/60 / indications of being unstable?
Synchronized Cardioversion
Doing what skill, while the AED is charging, will likely increases survivability?
Chest Compressions.
What is the purpose of chest recoil?
To maximize Cardiac Output.
