Methods Animals were randomly and equally divided into five groups: saline control group, positive drug control group, low-dose, medium-dose and high-dose crocetin group. Animals were anesthetized with urethane (1.2 g/kg), then followed by the perfusion of aconitine (10 μg/mL) through caudal vein in rats, or of ouabain (9 μg/mL) through external jugular vain in guinea pigs in a constant velocity of 0.1 mL/min, and the emergence time of ventricular fibrillation, ventricular extrasystole, ventricular tachycanlia and cardiac arrest were then detected and recorded. The recorded time was then translated to the cumulated amount of aconitine and ouabain. Experimental arrhythmia was induced by rapid injection of 4% CaCl2 (140 mg/kg), and the emergence time, persistence time, incidence and death of arrhythmia after the administration were observed.

The inhibitory efFect of deep somatic nerve stimulation on the HVEs does not depend upon the buffer nerves, but is related to the function of medial medulla oblongata.
上述结果表明：化学感受性反射能易化刺激下丘脑诱发的室性期前收缩，而压力感受性反射可以抑制这种室性期前收缩，但躯体传入冲动对这种心律失常的抑制作用并不依赖于缓冲神经的存在，而有赖于延做中线核群的完整性。
