Key result

Experimentally induced ventricular tachycardia and acute arteriovenous fistula resulted in an increase in catecholamines blood levels in anesthetized dogs.

Why the study?

Does experimentally induced ventricular tachycardia or acute arteriovenous fistula increase catecholamines blood level in anesthetized dogs?

Implication

No immediate clinical implications; leaves open translation of catecholamine responses from canine VT or AV fistula to human disease.

Structured PICO

Does experimentally induced ventricular tachycardia or acute arteriovenous fistula increase catecholamines blood level in anesthetized dogs?

P
Population
Anesthetized dogs subjected to experimentally induced ventricular tachycardia and acute arteriovenous fistula.

Intervention
Experimentally induced ventricular tachycardia and acute arteriovenous fistula

Outcome
Catecholamines blood levelsurrogate

Experimentally induced ventricular tachycardia and acute arteriovenous fistula increase catecholamine blood levels in anesthetized dogs, likely secondary to hemodynamic changes.

Cite This Study

Nakano et al. (1961) studied Anesthetized dogs. Experimentally induced ventricular tachycardia and acute arteriovenous fistula vs. Baseline/control levels was evaluated on Catecholamines blood level. Experimentally induced ventricular tachycardia and acute arteriovenous fistula resulted in an increase in catecholamines blood levels in anesthetized dogs.
