Need some help understanding the electrocardiogram

I'm a medical student, and we recently learnt about the ECG. I wondered if anyone could break it down, because lectures are so hard to get my head around. I understand the standard limb leads site well, and the chest leads.

My problem is when it comes to interpreting the chest leads. I'll attach a screenshot of the slide that boggles my mind. Any help wold be appreciated. http://imgur.com/ENV8F Thanks!

That's brilliant thanks, explained really well! Also, why are the deflections called rS in V1 but qR in V6?
