title: Bradycardia-associated episodic weakness, syncope, and aborted sudden death in cardiomyopathic Doberman Pinschers.
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.
