The d-wave polarity is what?

Explanation:
Polarity here refers to the sign of the d-wave component in the recorded signal. In the standard recording setup used for these materials, the d-wave appears as a positive-going deflection—meaning it rises above baseline when the d-wave occurs. So the polarity is positive. (If the montage were reversed, you could see a negative sign, but within these conventions it’s defined as positive.)
