Video Summary

Next question. Which of the following is most likely to contribute to the mechanism of the changes shown in the ECG below? Transmural gradient of sodium current across the right ventricle, transmural gradient of the transient outward potassium current across the right ventricle, a transient gradient of calcium current across the right ventricle, and the transmural gradient of the inward rectifier IK1 current across the right ventricle. And again, a couple of minutes here to consider the possibilities.
