Jm. Lin et al., LEFT ATRIAL APPENDAGE BLOOD-FLOW IN A CASE OF PERSISTENT ATRIAL STANDSTILL, International journal of cardiology, 57(1), 1996, pp. 97-99
Persistent atrial standstill, characterized by absence of atrial activ
ity on surface and intracavitary electrograms, absence of atrial mecha
nical activity, and inability to stimulate the atria electrically, is
a rare disorder. Left atrial appendage blood flow has been reported to
be related to P wave during sinus rhythm or local atrial electrogram
during atrial fibrillation. However, distinct and periodical LAA blood
flow was demonstrated in a patient with persistent atrial standstill
by transesophageal echocardiography.
