(repeat to a total of 3mg IV)
For poor perfusion with Bradycardia Treat, if the first line of treatment
is ineffective, what should be provided and what med should be
given? - ANSWER-Transcutaneous pacing
Dopamine 5-20mcg/kg/minute infusion
OR
Epinephrine 2-10mcg/min infusion
What is the first line drug for acute stable bradycardia and how do
you administer it? - ANSWER-Atropine given as 1mg IV q 3-5minutes
(up to 3mg IV)
Hoe does Atropine work? - ANSWER-Reverses the
cholinergicmediated decreases in the heart rate and AV node
conduction
Which two AV block types will not respond to Atropine? - ANSWER-
Mobitz type II second-degree AV block and third-degree AV block
,What is the preferred treatment for Mobitz type II second-degree AV
block and third-degree AV block? - ANSWER-TCP or B-adrenergic
(dopamine, epinephrine) support until transcutaneous pacing can be
achieved
If only 0.5mg of IV Atropine is given what consequence could it have?
- ANSWER-It can further lower the HR
What can be used if bradycardia is unresponsive to Atropine? -
ANSWER-B-adrenergic infusions (dopamine or epinephrine)
What must you consider before giving B-adrenergic infusions in
bradycardia? - ANSWER-The pt's BP/intravascular volume status for
hypovolemia

ANSWER-2-10mcg/min
Dopamine should be given at what dose/rate for Bradycardia? -
ANSWER-5-20mcg/kg/min
How does Transcutaneous Pacing (TCP) work and when should it be
used? - ANSWER-It delivers pacing impulses to the heart through
skin via cutaneous electrodes.
, for unstable bradycardia (hypotension, AMS, shock, ischemic chest
pain)
For light sedation within the RN scope of practice give which 3 things
should be given before TCP if the pt's condition allows for it? -
ANSWER--Parenteral narcotic
-Parenteral benzodiazepine
-Chronotropic infusion
How much of a safety margin (energy above the dose at which
consistent capture is observed) should you allow when using the
transcutaneous pacemaker? - ANSWER-2 mA
The HR that takes on clinical significance and is more likely to
contribute to arrhythmia in tachycardia is what rate? - ANSWER-
150/min or greater
What are the 7 rhythms associated with unstable tachycardia? -
ANSWER-1. Sinus Tachycardia
2. Atrial fibrillation
3. Atrial Flutter
4. Superventricular Tachycardia (SVT)
5. Monomorphic Ventricular Tachycardia (giant shark teeth-looking) 6.
Polymorphic Ventricular Tachycardia (Mutiple random shark
teethlooking)
7. Wide-complex tachycardia of uncertain type
