为进一步确定烟碱对大鼠心脏的作用，对描记烟碱作用后大鼠心电图进行分析，发现烟碱能引起大鼠心电图显示较长的QT间期，增加了PR间期及T波面积，与肾上腺素或去甲肾上腺素引起的QT间期延长相似，且能被M受体阻断剂阿托品所阻断，说明烟碱能够诱导局部释放乙酰胆碱或者作用于部分副交感神经控制的毒蕈碱受体。

Results:①In normal extracellular solution, the non-selective cholinergic agonist acetylcholine and the muscarinic agonist muscarine both caused the increace of [Ca2+]i in separately 21 out of 25 and 14 out of 18 VHCs I, while only 3 out of 20 and 2 out of 16 VHCs I had a weak increase of [Ca2+]i if investigated in calcium free extracellular solution; nicotine could increase the [Ca2+]i in 7 out of 32 VHCsⅠonly at enough high concentration(up to 10 mmol/L) in normal extracellular solution, this [Ca~(2+)]_i increase by nicotine at high concentration could not be investigated if at calcium free solution.
