Flutter vs coarse AFib: determine atrial regularity by taking big bites
TREATMENT:
Digoxin usually only helpful when already c a block (i.e. AF c 2:1 block) NOT c an SVT c 1:1 conduction.
AFib: IV Beta-block> IV digoxin > CCB (diltiazem) > Type IA to covert to SR
AFlutter: same as AFib
AT: same as AFib
AVNRT: CSM > adenosine > then Beta blockers > CCB > Digoxin PO. Consider eCV (not if low LVEF), ?procanamide , amio, sotalol.
Junctional: remove the cause, Amiodarone(, Beta-blocker, CCB).
ST: B blocker > CCB > Digoxin
MAT: Verapamil/ Diltiazem. CAREFUL of Beta-blockers b/c usually in pts with pulmonary dz. Amiodarone
