Population

Isolated hearts of 4 dogs with surgically induced right atrial enlargement (TI/PS dogs) and 3 control hearts

Intervention

Induction of atrial flutter and mapping of total endocardial activation using 192 pairs of recording electrodes

Comparator

Control hearts without surgically induced right atrial enlargement

Outcome

Atrial activation sequences during normal sinus rhythm and during arrhythmiassurrogate

In a canine model of right atrial enlargement, sustained atrial flutter is driven by right atrial reentry dependent on an area of functional block.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Establishes functional block as requisite for reentry in enlarged canine atria; leaves open applicability to human atrial flutter.
