Wait, are we sure about that? I thought it was more about the ST segment.

I agree with B, it makes the most sense here.

C seems unlikely, right atrial enlargement doesn't usually affect QRS width.
AM

I thought it could be A too, but not really a common cause.
NA

Definitely B, defective intraventricular conduction is a big one!

Right atrial enlargement sounds familiar, but I don't think it causes a wide QRS. I might lean towards B as well.
EL
Elden

I practiced a similar question last week, and I think defective intraventricular conduction was mentioned as a cause for wide QRS. So, B seems likely.
CH

I'm not entirely sure, but I feel like hypokalemia could affect the heart rhythm. Could it cause a wide QRS?
LU

I think I remember something about wide QRS complexes being related to conduction issues, so maybe B is the right answer?

Ah, I remember learning about this in class. A wide QRS complex is often associated with problems in the ventricles, like defective conduction. I'm pretty confident that's the right answer here.

I'm a bit unsure about this one. I know a wide QRS can be a sign of some heart condition, but I'm not sure which specific cause is being asked about here. I'll have to review my notes to refresh my memory.

Okay, let's see. A wide QRS complex can be caused by issues with ventricular conduction, so I'll focus on that. Defective intraventricular conduction sounds like the most likely option.

Hmm, this looks like a tricky one. I'll need to think through the possible causes of a wide QRS complex and see which one fits best.

You know, I bet the answer is a combination of all of them. Just turn the volume up to 11 and see what happens. That's how we do it in the real world, right?
RO

C) Right atrial enlargement.
UL

B) Defective intraventricular conduction.
NO

A) Hypokalemia.

Abnormal ST segment? Nah, that's just gonna mess with the ST part, not the QRS. This exam is trying to trick us, I tell ya!
EL
Elouise

That makes sense, abnormal ST segment could definitely affect the QRS complex.
BA
Barbra

I think the answer is D) Abnormal ST segment, as it can lead to abnormal depolarization.
AN

Hey guys, what if it's right atrial enlargement? I mean, that could definitely cause some disturbances in the QRS complex, right?
BE

C) Right atrial enlargement.
TH

B) Defective intraventricular conduction.
LE
Lezlie

A) Hypokalemia.
AL
Alecia

Hmm, I'm not so sure about that. Could it be hypokalemia? I remember that can also mess with the electrical signals in the heart.
MA
Mariann

But wouldn't hypokalemia cause a narrow QRS complex instead?
SH
Shayne

A wide QRS complex? Definitely got to be option B, defective intraventricular conduction. That's like the textbook answer, right?
SA
Sabra

I remember learning that abnormal ST segment can also be a cause of a wide QRS complex.
DU
Dulce
2 years ago
I think it's actually hypokalemia that causes a wide QRS complex.
RI
Rima

Yes, you're right! Defective intraventricular conduction can definitely cause a wide QRS complex.
EL
Elouise
2 years ago
I disagree, I believe the answer is A) Hypokalemia.
MA
Mariann

I think the answer is B) Defective intraventricular conduction.
