    摘要: The invention provides a method for determining the effects of an agent on repolarization of cells in vitro, comprising stimulating the cells with an energy source and under conditions sufficient and for a time sufficient to depolarize the cells, measuring the QT interval of the electrical signals output by the cells in response to the stimulating step, contacting the cells with an agent, re-stimulating the cells with the same energy source and under the same conditions as the first stimulating step and for a time sufficient to depolarize the cells, measuring the QT interval of the electrical signals output by the cells in response to the second stimulating step, and comparing the results of the measuring taken after the first and second stimulating steps to determine whether the agent affects repolarization of cells. The present invention also provides a method for determining the effects of an agent on conduction of cells in vitro.
