electrostatics - Confused medical student needs explanation of the electrocardiogram


From what I understand, as the heart depolarizes it turns into a lot of electric dipoles , the resultant of which can (somehow) be measured in the extremities. But how does this actually happen? How is the potential in the extremities changed by the heart? And why do they teach us that voltage is a vector (it's a scalar, isn't it?) Can someone tell me what the cardiac vector really is? Thanks
