Which lead on the ECG are we looking at?
First, impression is A-fib (absent P wave with irregular HR ~160 bpm). Patient needs a full cardiac workup. Transport to ER with IV NS slow drip (10 gtt/min) just to have a line open. (Bet ya thought I was gonna say Dextran

). O2 nasal cannula. Transport semi-reclined. Aspirin sublingual wouldn't hurt to prevent clotting and possible occlusive stroke.
