I agree with Theron, -30 seems to be the most appropriate mean QRS axis.

Wow, I guess the electrical activity in the heart is just going in circles or something. 120 degrees? That's like a ninja move, not an ECG reading!

I'm a little confused here. Is the question asking about the mean QRS axis or the mean axis of the entire ECG? That could make a difference in the answer.

Well, based on the extremity leads shown in the figure, I think -30 makes more sense.

90 degrees? Really? That would be a vertical axis, and the leads don't look like that at all. I'm going with 60 degrees.

Why do you think it's -30? Can you explain your reasoning?

Hmm, I'm not sure about this one. The leads seem to be showing a left-axis deviation, so I think the answer might be -30 degrees.

The mean QRS axis is clearly 60 degrees. This is the only option that aligns with the characteristic appearance of the extremity leads in the figure.

No, the extremity leads in the figure clearly point towards a mean QRS axis of 60 degrees.
