Physiologically — the most commonly observed pattern of AFlutter, known as " Typical " AFlutter — produces 2:1 negative deflections seen in the inferior leads ( as seen in Figure-3 ) — as a result of CCW ( C ounter C lock W ise ) rotation of a fixed reentrant circuit around the tricuspid valve annulus and through the cavo-tricuspid isthmus.
