Editing Atrial flutter (section)

====Sudden cardiac death====
Sudden death is not directly associated with atrial flutter.  However, in individuals with a pre-existing accessory conduction pathway, such as the [[Wolff-Parkinson-White syndrome#Bundle of Kent|bundle of Kent]] in [[Wolff-Parkinson-White syndrome]], the accessory pathway ''may'' conduct activity from the atria to the ventricles at a rate that the AV node would usually block.  Bypassing the AV node, the atrial rate of 300 beats/minute leads to a ventricular rate of 300 beats/minute (1:1 conduction).  Even if the ventricles are able to sustain a cardiac output at such a high rate, 1:1 flutter with time may degenerate into [[ventricular fibrillation]], causing hemodynamic collapse and [[death]].<ref>{{cite journal |url= https://www.ncbi.nlm.nih.gov/books/NBK507854/ | title= Sudden Cardiac Death | website= National Center for Biotechnology Information, U.S. National Library of Medicine | year= 2023 | pmid= 29939631 |access-date= 3 July 2021 | last1= Yow | first1= A.
