Plain-English summary
A group of 8 Doberman Pinschers with heart disease experienced episodes of weakness and fainting, sometimes leading to near-sudden death during exercise. These episodes were caused by a slow heart rate (bradycardia) that lasted 1 to 2 minutes in some dogs, followed by a rapid heart rate. During these fainting spells, the dogs showed signs like pale or bluish gums and dilated pupils. It's important for owners of Doberman Pinschers to be aware of these symptoms and consult their veterinarian for appropriate heart health monitoring and treatment options.

Abstract
Paradoxical sinus bradycardia and cardiac asystole resulted in episodic weakness, syncope, or aborted sudden cardiac death during exertion in 8 cardiomyopathic Doberman Pinschers. Bradycardias persisted for 1 to 2 minutes in 5 of 8 dogs, and were often followed by sinus tachycardia. Syncope was prolonged on multiple occasions in 5 dogs, and was accompanied by white, then cyanotic mucous membranes, mydriasis, and apparent sudden death.
