here a web site that could help you a little bit. but remember where the lead are place and in some case it can help you understand what it read. v1-v6 read the l ventricule and septal mostly( not to forget that the hearth is 3 dimension). avr read the right( that's what the r is for). avl the left (a gain the l). and guess what avf read... the foot ,so inferior axis in a way. lead 1,2,3 read the same way as a 3 lead monitoring. now you just have to remember the rule. if it come towards the electrode it is positive away negative. for example, avr is always negative cause the electricity move from sa node down and avr read.. right. but if you have a ventricular arythmia since the electricity would come from below in direction if the avr it will read... positive. there a little chart that the ena have in there market place that could help you. you may want to have a look at it.
