The significance of a deep Q wave in standard Lead III as an aid to the diagnosis of posterior myocardial infarction was established by Pardee1 in 1930. Since this time a deep Q3 has been of accepted value in this diagnosis. It has been recognized, however, that a significant Q wave in standard Lead III according to Pardee's criteria (25 per cent or more of the highest R wave in the standard leads) may be seen in normal patients. It is also known that a Q wave of apparently significant amplitude may be present in conditions other than myocardial infarction.
