30
Q

Afib

A

Results from multiple waves of electrical impulses in the atria, resulting in an irregular and rapid ventricular response –> ischemia and heart failure

Need AC because
Disorganized depolarization of the atria –> impaired atrial contraction –> risk of thrombosis and stroke

31
Q

Paroxysmal Afib
Persistent Afib
Longstanding persistent
Permanent

A

Paroxysmal: terminates spontaneously or w/ tx within 7 days

Persistent: last > 7 days

Longstanding: > 12 months

Permanent: no further action

32
Q

Goal HR in Afib

A

< 80 bpm

< 110 bpm if asymptomatic AND preserved EF
