• Atrial fibrillation “originates” near the junction of : Left Atrium & pulmonary veins
• This tissue represents a small group of myocyte that extend to the pulmonary veins
↪️Its function is to “contract” during atrial systole to prevent backflow of 🩸 to pulm veins

• Atrial flutter most commonly “originates” near a re-entrant circuit around : “Tricuspid Valve Annulus”
• Mechanism : slowing of the impulses through a region called “Cavotrcuspid isthmus”
• Refractory cases are usually managed by Cavotricuspid Isthmus Ablation
