Atrial Fibrillation versus Atrial Flutter1970-01-01T00:00:00+00:00A-flutter versus a-fib. Electrical impulses are shown in yellow. Note the re-entrant loop in the right atrium in a-flutter, and multiple ectopic sites in a-fib. In a-flutter, this is a 3:1 heart blockPT19Shttps://d3e1m60ptf1oym.cloudfront.net/3ba18320-e60e-4b50-bbfb-a3b5d96f70ff/aflutter_vs_afib_xlarge.jpghttps://d3e1m60ptf1oym.cloudfront.net/3ba18320-e60e-4b50-bbfb-a3b5d96f70ff/aflutter_vs_afib_mp4_hd_video.mp4
