Flutter Flashcards
Flutter is a
Macro reentrant circuit
Two types of flutter
Typical and a typical
Typical flutter occurs in the
Right atrium
Typical flutter uses what band of tissue as the pathway of slow conduction?
CTI
Cavotricuspid isthmus
Where is the CTI located?
Between the IVC and tricuspid valve (TVA)
Atypical flutter can occur
Anywhere in the atrium
Does not utilize the CTI as a slow conduction area
Atyp flutter is often facilitated by
Scar tissue
In flutter the IVC is
One end of the CTI, tissue in the IVC is non conductive
Tricuspid valve annulus
Outer ring of the the tricuspid valve. In typical flutter the circuit travels around the TVA
Counter Counterclockwise activation travels down the _____ and up the ______
Lateral wall
Right atrial septum
Clockwise activation travels down the _____ and up the ______
Right atrial septum
Lateral wall
