采用药理学方法，结合乙醛酸诱发儿茶酚胺（ＣＡ）荧光技术，研究了家兔静脉快速注射ＢａＣｌ２（７ｍｇ／ｋｇ）诱发包括心室颤动在内的严重室性心律失常的机制．结果提示：ＢａＣｌ２诱发的室性心律失常与内源性ＣＡ释放激动肾上腺素能α－受体有关．
Pharmacological methods combined with glyoxylate-induced catecholamine (CA) fluorescence were used to study the mechanism of intravenous bolus injection of BaCl2 (7 mg / kg) in rabbits to induce severe ventricular arrhythmia including ventricular fibrillation. The results suggest that BaCl2-induced ventricular arrhythmias are associated with the release of agonistic adrenergic alpha-receptors by endogenous CA.
