Q

What are the four types of atrial fibrillation?

A
  1. Paroxysmal - terminates spontaneously and recurs
  2. Persistent - 7D, requiring cardioversion
  3. Permanent - >1 year, failed cardioversion
  4. Lone afib - afib in young patient (<60) with no cardio-pulmonary disease

Q

What is the time period that you are monitoring for Afib if someone comes in claiming heart palpitations and what are the interventions?

A
  1. Afib <48 hours - start IV anticoag, cardiovert, do 4 weeks of oral anticoag after
  2. Afib >48 hours - Echo for clot
    * If clot - anticoagulate for 4-12 weeks
    * If no clot - cardiovert same day then 4 weeks of anticoag
