Electrocardiographic (ECG) criteria:
1) R > S in V1 & V2
2) S > R in V5 & V6
3) R in V1 > R in V5
4) right axis > 110 degrees
5) QRS < 112 msec (not right bundle branch block)
Other causes of R in V1:
1) right bundle branch block - prolonged QRS
2) posterior myocardial infarction
a) generally occurs in association with inferior wall MI
b) Q's in II, III, aVF from inferior wall MI
