(19) Atrial fibrillation thresholds were determined at baseline (0.0% inhalational anesthetic), 0.5 minimal alveolar concentration (MAC), and 1.0 MAC of halothane (n = 8) and isoflurane (n = 8).
(20) All patients with emboli were in atrial fibrillation.
Fibrillary
Definition:
(a.) Of of pertaining to fibrils.
Example Sentences:

(6) Immunoblotting showed a serum and CSF antibody apparently directed against glial fibrillary acidic protein.
(7) We examined the effect of lactic acid on cultured human glioma cell lines expressing glial fibrillary acidic protein (GFAP), vimentin and neuron-specific enolase (NSE).
