persistent AFib

Answer 8

• Lasts longer than 7 days
• including those terminated by cardioversion

Question 9

Why we synchronize in direct current cardioversions…

Answer 9

Avoid the post-shock complication of VFib or VT!

Question 10

CHB stable sequence

Answer 10

Transcutaneous pads- evaluate for reversibility

non reversible- needs Pace maker

reversible- treat cause

Question 11

Unstable CHB sequence

Answer 11

atropine- transcutaneous pads-

if Low BP–> IV Dopamine

if HF—> IV Dobutamine

normal BP, no HF–> transvenous pacing

when stabilized assess for reversible causes—- none or CHB persists (PPM)
