-angina
-dizziness or syncope
-confusion or disorientation
-SOB


●● Bradycardia - Stable
Answer: continue to monitor


●● Bradycardia - Unstable
Answer: -least invasive first - if O2 issues, sit up, and apply O2 before
anything else
-1: atropine
-2: epi/dopamine infusion
-3: pacing (transcutaneous, temporary, or permanent)

,●● Transcutaneous pacing
Answer: -need versed/morphine first d/t pain


●● Atrial Paced Beats
Answer: narrow QRS


●● Ventricular Paced Beats
Answer: wide


●● AV Paced beats
Answer: replaces atrial kick


●● Failure to Capture
Answer: -see pacer spikes but on some of these there is no QRS
following
-concern: CO - focused assessment on looking at CO (hemodynamics
with VS, chest pain, dizziness, SOB = decrease in CO)


●● Failure to Pace
Answer: -Have pacemaker artifact but there is one spike that is missing
-cause: battery (generator) issue, issues with the leads

, -prevent with limiting affected shoulder mobility so they do not dislodge
wire


●● Failure to Sense
Answer: -too high on the pacemaker, so cannot see what patient's
underlying rhythm is
-concern: R on T


●● Sinus Tachycardia
Answer: -tx: fix underlying cause (pain, fever, dehydration, anxiety,
drugs (caffeine), hypoxia
-pt. needs to be stable to perform vagal maneuver


●● SVT
Answer: -typically >150
-P waves buried in T waves
-an atrial rhythm
-increase in HR and a decrease in SV so coronary arteries dont get
perfused so they can have chest pain


●● SVT Unstable
Answer: -synchronized cardioversion first, give meds to sedate if there is
time
