Video Summary

Next question, and I'll start this video while I read. The video shows the activation sequence in the left atrium during a tachycardia. Which of the following is most likely to be a characteristic of this tachycardia? A, decreasing conduction velocity will terminate the tachycardia. B, decreasing dispersion of repolarization will terminate the tachycardia. C, increasing the wavelength will terminate the tachycardia. Or D, an increase in the refractory period increases the likelihood of developing this tachycardia. Again, I'll give you a little chance to peruse the movie and consider the answers.
