Key result
Sudden death syndrome in broilers is associated with acute cardiovascular failure from ventricular fibrillation.
Why the study?
The cardiac mechanism underlying sudden death syndrome in broiler chickens was not well characterized.
Population
Six broiler chickens dying of sudden death syndrome and six control chickens
Comparison
Terminal cardiac activity in sudden death syndrome chickens vs control chickens
Design
Case-control study with electrocardiographic monitoring

Links VF to sudden death in broilers; hypothesis-generating for cardiac mechanisms but leaves open translation to humans.
Case-Control (n=12)
Olkowski et al. (1997) conducted a case-control in Sudden death syndrome (n=12). Sudden death syndrome vs. Control chickens killed by cervical dislocation was evaluated on Terminal cardiac activity (ECG tracing). Sudden death syndrome in broiler chickens was associated with acute cardiovascular failure caused by ventricular fibrillation, whereas control chickens exhibited normal sinus rhythm.
