I'm trying to understand something about ECG readings. In a normal person, when you look at the R wave in the V3 and V4 chest leads, is it due to major ventricular depolarization or septal depolarization? I could really use some help figuring this out.

In a normal person, the R wave in V3 and V4 chest leads is primarily due to major ventricular depolarization. This is a normal electrical activity of the heart during the cardiac cycle.

I'm a bit worried because for the past two days, I've been having some breathing discomfort, but it's not constant. It mostly happens after I've eaten in the afternoon and at night. I'm also experiencing some pain in my shoulder. I just started Zumba exercises, and it seems like this all started the day after. Do you think there's a connection? What's going on with my breathing and shoulder?

I'm a bit concerned because my resting heart rate is around 80 while I'm just sitting at my desk doing nothing. Is this something I should be worried about?

A resting heart rate of around 80 beats per minute is generally considered within the normal range for adults. However, if you are experiencing symptoms such as dizziness, shortness of breath, chest pain, or fainting spells along with the elevated heart rate, it may be worth consulting with a healthcare provider. In the meantime, you can try managing stress, getting regular exercise, and maintaining a healthy diet.
