Key result
Beta-adrenergic receptor antagonists (nadolol, sotalol, atenolol, and propranolol) were equally effective in increasing the electrical threshold for induction of ventricular fibrillation in dogs.
Why the study?
Do beta-adrenergic receptor antagonists increase the electrical threshold for induction of ventricular fibrillation in anesthetized dogs?
Do beta-adrenergic receptor antagonists increase the electrical threshold for induction of ventricular fibrillation in anesthetized dogs?
Beta-adrenergic receptor antagonists increase the ventricular fibrillation threshold in dogs via mechanisms not solely attributable to beta-blockade or specific alterations in cardiac cell membrane properties.

Suggests non-class effects on VF threshold in dogs; leaves open human translation and mechanism-targeted trials.
Patterson et al. (2008) studied Ventricular fibrillation. Beta-adrenergic receptor antagonists (nadolol, sotalol, atenolol, propranolol) was evaluated on Electrical threshold for induction of ventricular fibrillation. Beta-adrenergic receptor antagonists (nadolol, sotalol, atenolol, and propranolol) were equally effective in increasing the electrical threshold for induction of ventricular fibrillation in dogs.
