Haha, really? Amplitude of the U wave? What is this, amateur hour? I bet the person who wrote that answer option has never even seen a proper ECG in their life.

So, the key is really in the QRS complex width and presence of P waves. Got it.

Ventricular rhythms have wide QRS complexes and usually no visible P waves.

Looks like the exam writers are trying to trip us up with those other options, but the correct answer is definitely A. Gotta keep your wits about you on these tests!

But what about ventricular rhythms? How do they differ?

I agree with Dominga, because supraventricular rhythms have narrow QRS complexes and visible P waves.

I think the differentiation is based on the duration of the QRS complex and the presence of P waves.

I can't believe they're even asking this. The QRS complex and P waves are the bread and butter of ECG interpretation. Anyone who's been in the field for more than a week should know this!

The duration and width of the QRS complex, along with the presence or absence of P waves, are the key factors in differentiating supraventricular and ventricular rhythms. This one's a no-brainer!
