PCCN: Bradycardia and pacemakers
Questions and Correct Answers.
Pacemakers Indications - Answer Bradycardia symptomatic
Type 2 mobitz Second Degree AV Heart Blocks
Third Degree AV Block.
Why is an asynchronous mode for pacemaker not recommended? - Answer Because of the
risk for R on T phenomenon.
Which mode for a pacemaker is recommended? - Answer Synchronous or "demand pacing"
What does atropine do? What does atropine treat? What are the side effects? - Answer
inhibits parasympathetic nervous system.
Treatment for symptomatic bradycardia.
1 mg IVpush 3-5 minutes.
Side effects are blurry vision, tachycardia, urinary retention.
Transcutaneous pacing pad placement - Answer 1. Anterior and posterior
2. Anterior and lateral
Settings are:
VVI mode only.
Demand synchronous mode.
Starts at 50 mAV and must palpate a pulse.
A bundle branch block is seen because the ventricles are shocked at different times. Right
ventricle then left ventricle will contract.
Emergent pacing setting that is commonly used is - Answer VVI - commonly used pacemaker
settings.
VVO - is a big no-go because the risk for R-ON-T phenomenon, risk for arrhythmia.
What does failure to capture mean on the pacemaker? How do we fix this? - Answer There is
pacing, but there is no follow-up with QRS.
