used frequently in electrophysiology because there is a high risk of stroke in atrial fibrillation or flutter
Heparin
this anticoagulates patients right away, unlike coumadin
unfractionated heparin: given intravenously
LWMH: patients can give it themselves with injection at home
Warfarin
used in a majority of patients with atrial fibrillation
even if you go back to sinus rhythm, atrium can still be stunned, so still anticoagulate these patients
one exception is younger patients with no other medical problems (lone atrial fibrillation)
3-5 days to achieve full therapeutic effect; target INR is between 2 and 3
