Original publication title: Presumptive partial atrial standstill secondary to atrial cardiomyopathy in a Greyhound.
Plain-English summary
A 6-year-old male Greyhound was diagnosed with a rare heart condition called partial atrial standstill, which caused his heart's upper chambers to not function properly. Over 14 weeks, he developed serious heart failure symptoms, including difficulty breathing and lethargy. A biopsy revealed that his heart muscle had significant damage due to a condition called atrial cardiomyopathy, where the heart tissue is replaced with fatty tissue. Unfortunately, despite the diagnosis, the treatment options for this condition are limited, and the prognosis can be poor.

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.
