I’m surprised it’s not 120, that’s usually a common guess!

I thought it could be 90, but 60 makes sense too.

Wait, are we sure it's not -30? That seems off.

I think the mean QRS axis is around 60.

I recall that the mean QRS axis can vary, but I think I ruled out -30. I’m stuck between 60 and 90.

I feel like I should be able to calculate this, but the angles are throwing me off. Was it 60 or 90 degrees?

I think I saw a similar question in our review session. I might lean towards option B, but I’m not completely confident.

I remember practicing QRS axis determination, but I’m not sure how to apply it to these leads.

No problem, I've got this. Determining the QRS axis is a straightforward process, I just need to apply it correctly.

Wait, I'm a little confused on how to approach this. I better review my notes on interpreting ECG leads.

Hmm, this looks like a tricky one. I'll need to carefully examine the leads and think through the axis calculation.

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.

Brande

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.

Donte

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.

I disagree, I believe it is -30.

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.
