FA doesn't have that many ecg tracings or much info about where exactly the precordial leads are located (V1-6) or relationships between leads and locations of the heart. There's not much of this in Kaplan either. But some of the Qbank questions I've seen expected us to know this... I don't know if this is something that I really need to know for boards or if I should just blow it off as the question being too nitpicky???
