Okay, next question. Cellular action potentials are recorded before and shown here in the dotted line, and after in the solid line and intervention. Which of the following best explains the action potential changes produced by this intervention? A, if Aberdeen induced funny current or IF blockade, B, adenosine activation of A1 adenosine receptors, C, late sodium current block by rinolazine, or D, amiodarone-induced block of the slow component of the delayed rectifier, IKS? Again, give you some time to consider the answers.
