Abstract:
Persistent atrial standstill is a rare arrhythmia in both human and veterinary patients. In recent decades, cases of partial atrial standstill have been recognized in humans. We describe a case of presumptive partial atrial standstill in a Greyhound, in which there was disparate left and right atrial electromechanical function and rapid progression to congestive heart failure over the span of fourteen weeks. An atrial cardiomyopathy characterized by severe, diffuse, fibrofatty replacement of the atrial myocardium was identified histologically.
