Psychologic stress reduced the threshold for repetitive ventricular response in dogs, indicating electrical instability and a predisposition to ventricular fibrillation.
Absolute Event Rate: 0% vs 0%
A psychologically stressful environment reduced the threshold of the dog's ventricle for repetitive response. Elicitation of such a response indicates the presence of electrical instability and a predisposition to ventricular fibrillation, the mechanism of sudden death.
