Telemetry Exam 3 with Questions
SOLVED 100%
First degree heart block appearance - ✔✔prolonged PR interval — delay in conduction from SA to AV
first degree heart block causes - ✔✔sleep/athletes, AMI, endocarditis, AV node injury,
amiodarone, digoxin
first degree heart block treatment - ✔✔None unless related to medication, then reduce dose or
DC; or atropine for symptomatic bradycardia
Type 1 Second Degree Heart Block appearance (wenkebach) - ✔✔progressively lengthening
PR interval until one drops resulting in a missing QRS complex; A rate and V rate will be different
causes of wenkebach - ✔✔valve disease, mitral valve prolapse, rheumatic heart disease
wenkebach treatment - ✔✔atropine if symptomatic bradycardia
Type 2 Second Degree Heart Block - ✔✔more P waves than QRS complexes; P waves will be
uniform and "plot out" (check for one hidden in the T wave!)
Type 2 Second Degree Heart Block treatment - ✔✔notify MD (potential to progress to third degree)
— if unstable, transcutaneous pacing
Complete (third degree) heart block - ✔✔no relationship between P waves and QRS
complexes, complete divorce
Complete heart block treatment - ✔✔dopamine drip, epinephrine, transcutaneous pacing
, atropine dose - ✔✔1 mg every 3-5 mins with a max of 3 mg
dopamine dose - ✔✔2-20 mcg/kg/min
what do you need to give before transcutaneous pacing - ✔✔conscious sedation
adenosine dose - ✔✔6 mg fast followed by a 20 mL flush; second dose 12 mg
amiodarone alive dose - ✔✔150 as a bolus over 10 mins
amiodarone dead dose - ✔✔300 as a push
the H's - ✔✔hypoxia, hydrogen ions, hypothermia, hypovolemia, hypo/hyperkalemia, hypoglycemia
the T's - ✔✔toxins, tamponde, tension pneumothorax, thrombosis
what drug do you give for polymorphic vtach? - ✔✔magnesium 1-2g
what is the dose for epinephrine? - ✔✔1mg
P wave represents - ✔✔atrial depolarization; should be smooth, upright and regular
QRS complex represents - ✔✔ventricular depolarization
the T wave represents - ✔✔ventricular repolarization
Normal ventricular rate (SA node) - ✔✔60-100
